  1. Hi, I needed a way to see how much of my C++ stack was being consumed in my MSP application - the traditional way is to "poison" the stack with a known pattern, and then to see how much of it gets burnt away. So I wrote the following - hope folk find it useful: The following code allows you to simply do this and to check at any point how much of the pre-allocated stack was consumed during peak usage, i.e. how close your app got to the bottom of the stack, or indeed, whether it over-ran. The TI CCS documentation is completely wrong in the names it gives for the global symbols that define the size and start of the stack - needs to be updated, Stick this code (or similar) wherever you want to report on/check stack usage <smallest number of byes left free on the stack since initialisation>/<configured size of the stack>. #if defined(STACK_CHECK) std::printf( "Stack: %d/%d\n", stackMinFreeCount(), stackMaxSize() ); #endif and then, in your main code you need to poison the stack as early as possible and then define the reporting routines: // Define STACK_CHECK to include stack usage diagnostics #define STACK_CHECK #if defined(STACK_CHECK) #define STACK_INIT 0xBEEF // Pattern to use to initially poison the stack extern uint16_t _stack; // Start of stack (low address) uint16_t stackMinFreeCount(void); uint16_t stackMaxSize(void); #endif #if defined(__cplusplus) extern "C" { #endif #if defined(__TI_COMPILER_VERSION__) || \ defined(__GNUC__) int _system_pre_init( void ) #elif defined(__IAR_SYSTEMS_ICC__) int __low_level_init( void ) #endif { //... stuff... #if defined(STACK_CHECK) // // Poison the stack, word by word, with a defined pattern // // Note that _system_pre_init is the earliest that we can // do this and that it may not be possible in TI-RTOS // // When we call the __get_SP_register intrinsic (same on IAR & CCS), it will return the address // of the RET address for the caller of this routine. Make sure that we don't trash it!! // register uint16_t *stack = &_stack; // Address of lowest address in .stack section register uint16_t *stack_top = reinterpret_cast<uint16_t *>(__get_SP_register()); do { *stack++ = STACK_INIT; // Poison stack addresses } while (stack < stack_top); // Stop before top of stack to leave RET address #endif return 1; } #if defined(__cplusplus) } #endif #if defined(STACK_CHECK) /** * Check how deep the stack usage has been * * \return \c uint16_t Minimum number of bytes to bottom of stack */ extern uint16_t __STACK_END; // End of data extern uint16_t __STACK_SIZE; // Linker-set size of stack uint16_t stackMinFreeCount(void) { const uint16_t *stack = &_stack; uint16_t freeCount = 0; while (*stack == STACK_INIT && stack++ <= &__STACK_END) { freeCount++; } return freeCount << 1; } /** * Return size of C++ stack * * Set by the linker --stack_size option * * \return \c uint16_t Configued maximum size of the stack in bytes */ uint16_t stackMaxSize(void) { return static_cast<uint16_t>( _symval(&__STACK_SIZE) ); } #endif int main(void) { ... stuff #if defined(STACK_CHECK) std::printf( "Stack: %d/%d\n", stackMinFreeCount(), stackMaxSize() ); #endif ...stuff }
  2. Hello, I have a problem with strange behavior of gcc compiler, which does not seem to generate interrupt vectors correctly. I tried to search for hints on the forum, but could not find any helpful information. I have the following C code: void __attribute__((interrupt(TIMER0_A0_VECTOR))) timer0_isr(void) { //IMPORTANT !!!!!!! //Clear TAIV by reading it !!!! (void) TAIV; /* ... */ } void __attribute__((interrupt(TIMER0_A1_VECTOR))) timer0_a1_isr(void) { P1OUT ^= PIN0; } volatile int qq; __attribute__((interrupt(USCIAB0TX_VECTOR))) void usci_tx_isr(void) { qq=1; P1OUT ^= PIN6; IFG2 &= ~UCA0TXIFG; } __attribute__((interrupt(USCIAB0RX_VECTOR))) void usci_rx_isr(void) { qq=2; P1OUT ^= PIN6; if(IFG2 & UCA0RXIFG) { (void) UCA0RXBUF; } IFG2 &= ~UCA0RXIFG; } Only the TIMER0_A0_VECTOR ISR contains meaningful code at the moment, and the other 3 procedures are just placeholders. For some strange reason, the only ISRs which are linked in the executable code to the interrupt vector table are TIMER0_A0_VECTOR and TIMER0_A1_VECTOR: Disassembly of section .vectors: 0000ffe0 <__ivtbl_16>: ffe0: 6c c1 bic.b @r1, r12 ffe2: 6c c1 bic.b @r1, r12 ffe4: 6c c1 bic.b @r1, r12 ffe6: 6c c1 bic.b @r1, r12 ffe8: 6c c1 bic.b @r1, r12 ffea: 6c c1 bic.b @r1, r12 ffec: 78 c4 bic.b @r4+, r8 ffee: 8e c4 6e c4 bic r4, -15250(r14);0xc46e(r14) fff2: b8 c3 6c c1 bic #-1, -16020(r8);r3 As==11, 0xc16c(r8) fff6: 6c c1 bic.b @r1, r12 fff8: 6c c1 bic.b @r1, r12 fffa: 6c c1 bic.b @r1, r12 fffc: 6c c1 bic.b @r1, r12 fffe: 00 c0 bic r0, r0 I must be doing something wrong, but I can't find where is the mistake.

EDIT: Moving void before __attribute__ has no effect.
  3. I noticed that if you use the TI arm compiler in CCS 6.x you can easily run code from ram. Unfortunately, it doesn't seem like they have implemented that for the arm-none-eabi-gcc compiler. Attached is a zip file project you can import into CCS. It is configured to run the msp432 at 48MHz using the high frequency crystal. It is also configured to generate small code using the nano.specs newlib configuration. In the default linker script, the data segment uses all the available ram starting at the base address of 0x20000000. The msp432 provides another bus address for SRAM at the base address of 0x01000000. This alias address is used to provide single cycle access to code in ram. I modified the the linker script in this project (msp432p401r.lds) so that the first 512 bytes of ram are reserved for code. /* adjust based address for fixed size of 512 bytes (0x200) for code in ram */ /* NOTE: if you change this size, make sure you adjust .vtable offset also */ SRAM_DATA (RW) : ORIGIN = 0x20000000+0x200, LENGTH = 0x00010000-0x200 Additonally, a new section called .ramfunc is used to collect any code put into the ".ramfunc" section. You do this using the gcc specific _attribute__((section(".ramfunc"))) directive. When the chip resets, code has been added to copy the instruction code from flash to ram. extern uint32_t __ramfunc_load__; extern uint32_t __ramfunc_start__; extern uint32_t __ramfunc_end__; void resetISR(void) { /* Copy .ramfunc code and data segment initializers from flash to SRAM. */ volatile uint32_t *pui32Src, *pui32Dest; pui32Src = &__ramfunc_load__; for(pui32Dest = &__ramfunc_start__; pui32Dest < &__ramfunc_end__; ) { *pui32Dest++ = *pui32Src++; } ... Attachment blink_cmsis_gcc.zip: blink_cmsis_gcc.zip In CCS, go to Project Menu and select the "Import CCS Projects ..." and select the archive file button. Use the file dialog to select the location where you downloaded the attached blink_cmsis_gcc.zip file. BTW: This is using the new CMSIS headers. Running in the debugger (note the address 0x10000FC of the code in the disassembly window)
  4. I'm trying to set up an eclipse / gcc / gdb / mspdebug based development environment to work on a custom msp430 based board that the company I work for produce. I have set up eclipse with the tools which come with ubuntu 15.04, and it's almost working apart from a weird bug in the debugger. When you watch a local variable in the main function, eclipse displays an incorrect value. This bug has been around for a while, as I've noticed it before (see this and the following page: http://forum.43oh.com/topic/1419-eclipse-plugin-for-mspdebug-and-msp430-gcc/page-3). The bug has been fixed in the most recent version of mspgcc from the old sourceforge site, but this is 2 years out of date now, and the development has moved to a project hosted by texas instruments: http://www.ti.com/tool/msp430-gcc-opensource . I would like to use the most recent version from ti if possible; I've tried compiling it and it builds OK, but I can't find a compatible libc and set of device specific header files which will work with it. When I try to use the libc that comes with ubuntu, it says it's incompatible. Also, when I pass the flag '-mmcu=msp430f5510', which used to work before, msp430-gcc throws an error. I've also noticed that the msp430 support appears to have been merged back into the upstream mspgcc (and presumably the other gnu tools), which is another way I've thought of going. So my question is, given all this, what's the best way to go to set up an up to date open source toolchain for the msp430? I could just compile the most recent version from the old sourceforge project, but would rather use something more up to date if that is possible.
  5. I have a program of about 40 KB (I use FAT32 through FatFs, that takes a lot of memory) that I developed using msp430-gcc 4.6.3 for a MSP430F5529 (that has 128 KB Flash). I am trying to move it to msp430-gcc 4.9.1 (downloaded from TI) but am getting the following errors upon linking: /opt/ti/gcc/bin/msp430-elf-gcc -I /opt/ti/gcc/include -mmcu=msp430f5529 -Os -g -c -o

  6. I'm port some code over to GCC (GNU_4.6.3:MSPGCC compiler inside CCS6.1) to take advantage of existing driver code for some of my devices. After clearing all basic errors, my build fails with this error: .../energia-0101e0014/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3/../../../../msp430/bin/ld.exe: error: no memory region specified for loadable section `.noinit.crt0' gmake: *** [main.o] Error 1 gmake: Target `all' not remade because of errors. How do I fix that? NOTE/CLUE: I tried making a new, blank GNU_4.6.3:MSPGCC project in CCS, and it gets identical compile errors. However, a new "Energia Sketch" does not have this problem. What is the difference between an "Energia Sketch" and a regular project? If the end-functionality is identical, I can just switch project types, but I don't know if a sketch project has any "gotcha"s that I will regret later. In case anything else is useful, here is the full console output of a failed compile: **** Build of configuration Debug for project MyDevicesGCC **** "C:\\TI\\ccsv6\\utils\\bin\\gmake" -k all 'Building file: ../main.cpp' 'Invoking: GNU Compiler' "C:/.../energia-0101E0014/hardware/tools/msp430/bin/msp430-gcc.exe" -c -mcpu=430x -mmcu=msp430f5529 -D__MSP430_HAS_USCI_A0__ -D__MSP430_HAS_USCI_B0__ -D__MSP430_HAS_USCI_B1__ -D__MSP430_HAS_USCI_A1__ -I"C:/.../energia-0101E0014/hardware/tools/msp430/msp430/include" -I"C:/.../energia-0101E0014/hardware/msp430/libraries/Wire" -I"C:/.../energia-0101E0014/hardware/tools/msp430/msp430/include" -I"C:/.../ElectronicsProjects/FlightControlsGCC/MyDevicesGCC/HeadersGCC" -I"C:/.../energia-0101E0014/hardware/msp430/variants/launchpad_f5529" -I"C:/.../energia-0101E0014/hardware/msp430/cores/msp430" -I"C:/TI/ccsv6/ccs_base/msp430/include_gcc" -Os -g -gdwarf-3 -gstrict-dwarf -Wall -MMD -MP -MF"main.d" -MT"main.d" -o"main.o" "../main.cpp" In file included from C:/TI/ccsv6/ccs_base/msp430/include_gcc/msp430f5529.h:63:0, from C:/TI/ccsv6/ccs_base/msp430/include_gcc/msp430.h:760, from C:/.../energia-0101E0014/hardware/msp430/cores/msp430/Energia.h:4, from ../main.cpp:1: C:/TI/ccsv6/ccs_base/msp430/include_gcc/iomacros.h:70:0: warning: "__interrupt" redefined [enabled by default] <built-in>:0:0: note: this is the location of the previous definition In file included from C:/TI/ccsv6/ccs_base/msp430/include_gcc/msp430.h:760:0, from C:/.../energia-0101E0014/hardware/msp430/cores/msp430/Energia.h:4, from ../main.cpp:1: C:/TI/ccsv6/ccs_base/msp430/include_gcc/msp430f5529.h:4806:0: warning: "__MSP430_HAS_USCI_A0__" redefined [enabled by default] <command-line>:0:0: note: this is the location of the previous definition C:/TI/ccsv6/ccs_base/msp430/include_gcc/msp430f5529.h:4851:0: warning: "__MSP430_HAS_USCI_B0__" redefined [enabled by default] <command-line>:0:0: note: this is the location of the previous definition C:/TI/ccsv6/ccs_base/msp430/include_gcc/msp430f5529.h:5123:0: warning: "__MSP430_HAS_USCI_A1__" redefined [enabled by default] <command-line>:0:0: note: this is the location of the previous definition C:/TI/ccsv6/ccs_base/msp430/include_gcc/msp430f5529.h:5168:0: warning: "__MSP430_HAS_USCI_B1__" redefined [enabled by default] <command-line>:0:0: note: this is the location of the previous definition ../main.cpp: In function 'int main()': ../main.cpp:37:20: warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings] ../main.cpp:49:13: warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings] ../main.cpp:85:16: warning: unused variable 'repeats' [-Wunused-variable] 'Finished building: ../main.cpp' ' ' 'Building target: MyDevicesGCC.out' 'Invoking: GNU Linker' "C:/.../energia-0101E0014/hardware/tools/msp430/bin/msp430-gcc.exe" -mcpu=430x -mmcu=msp430f5529 -D__MSP430_HAS_USCI_A0__ -D__MSP430_HAS_USCI_B0__ -D__MSP430_HAS_USCI_B1__ -D__MSP430_HAS_USCI_A1__ -Os -g -gdwarf-3 -gstrict-dwarf -Wall -Wl,-Map,"MyDevicesGCC.map" -o"MyDevicesGCC.out" "./main.o" -T"../msp430f5529.ld" -Wl,--start-group -l"c" -l"gcc" -Wl,--end-group c:/.../energia-0101e0014/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3/../../../../msp430/bin/ld.exe: error: no memory region specified for loadable section `.noinit.crt0' collect2: ld returned 1 exit status gmake: *** [MyDevicesGCC.out] Error 1 gmake: Target `all' not remade because of errors. **** Build Finished ****
  7. I know that the first word is the address of the top of the stack. In startup_gcc.c file in the stellarisware projects, the address of the reset_isr subroutine is stored in the second word space in the _text section. In the objdump of the blinky.axf file, a value of 0x2d1 is stored at address 0x04 in _text section. But the reset_isr subroutine is stored at address 0x2d0. This is confusing me. Isn't a value of 0x2d0 supposed to be at address 0x04 in _text section? Please explain me where I am wrong. I have attached the objdump of blinky.axf here.

  8. How can I add a switch to the g++/gcc command line (or do something equivalent) in Energia? I am importing a library (FastLED) which generates a bunch of warnings about needing -std=c++11 Example warning message: FeatureDemo.ino:655:98: warning: extended initializer lists only available with -std=c++11 or -std=gnu++11 [enabled by default] I would like to make those warnings go away (both for me, and be able to tell anyone else using the library how to make them go away). I have hunted through the menus, through the customization file and looked at the gcc documentation (for environment variables, etc.) So far haven't found how to either add this to the command line Energia uses to invoke gcc, or how to tell gcc to do the same thing by other means. Thanks.
  9. I'm getting this error: main.c: In function 'Timer_A': main.c:150:28: error: MSP430 builtin functions only work inside interrupt handlers __bic_SR_register_on_exit(CPUOFF); // Clear CPUOFF bit from 0(SR) ^ makefile:23: recipe for target 'main.o' failed With this code: // TimerA interrupt __attribute__((__interrupt__(TIMERA0_VECTOR))) Timer_A (void) { iflag |= BIT0; // Set BIT0 flag __bic_SR_register_on_exit(CPUOFF); // Clear CPUOFF bit from 0(SR) } For some reason msp430-elf-gcc thinks my ISR isn't an ISR Any ideas? I emailed one of the red hat guys who submitted the GCC patch with the function that checks whether a function is an interrupt handler or not.
  10. Greetings, I am currently working on a personal project using Tiva Launchpad together with Eclipse Kepler IDE and GNU ARM Embedded Tools (gcc version 4.8.2). Last week my efforts were focused on making the "usb_dev_serial" example (Tivaware 2.0.1.11577) work with that development setup (also i'm using it all on Windows 8). So far, a simple I2C master + button interrupt + LED toggling example I've made with this development configuration is working OK. When the USB module was added ("usb_dev_serial" skeleton added to my project), some compiling issues arised, but got fixed after I put "libusb.a" as resource library for the linking process. Unfortunately, some linking problems appeared (CDT build console exposed below): C:\ti\TivaWare_C_Series-2.0.1.11577\usblib\gcc\libusb.a(usbdcdc.o): In function `HandleRequests':

  11. I have recently received my Stellaris Launchpad and I'm building a toolchain to code for it using GNU+Linux. So far I have the cross compiler+lm4tools+stellarisware running. I can build the stellaris examples and flash them without problems. As I want to do some signal processing with my board, I'd like to build the CMSIS library. At least the DSPLib part (I don't need the RTOS right now). The library zip file has some scripts to build it using Keil, but as I'm a GNU+Linux user, I can't run Keil IDE. Also unfortunately, I'm a total noob when talking about autotools, so... Has anyone been able to build this library using GCC? Does anyone have a Makefile to automate building it? Thanks in advance!
  12. Hi, I've never noticed that the license for the examples of the stellaris launchpad were closed, they say explicitly that: # Texas Instruments (TI) is supplying this software for use solely and # exclusively on TI’s microcontroller products. The software is owned by # TI and/or its suppliers, and is protected under applicable copyright # laws. You may not combine this software with “viral” open-source # software in order to form a larger program. I wasn't very comfortable with this and I finally decided to write the needed linker script, startup file and the useful Makefile from scratch and license them with a BSD license. You can find my impressions here and the code in this github repository. Right now it doesn't support Stellarisware (It's basically the first working version) but I'm planning to add support for libraries in the Makefile as soon as I have time! I don't think it would be so difficult! Of course the sofware it's opened, so: every help, suggestion, bug issue it's welcome! I hope this would be useful in any way!
  13. I didn't see any posts on whether or not cygwin was a usable environment. I figured I would give it the college effort and see if I could build up a toolchain that allows me to compile and flash from within my editor of choice (Vim). The basic groundwork is laid out, and I have to say that I really didn't have to do any original work as it was basically all adapted from linux tutorials. If anyone is interested, I wrote up my experience at http://underwaterwhistler.blogspot.com/2013/01/getting-started-with-stellaris-launchpad.html
  14. I'm new here so hi. I have a problem compiling stellarisware with a custom build of gcc. I'm using the custom build because I want to learn how to build an arm toolchain on linux. I used buildroot to build everything. The problem I'm having is that on the qs_rgb example there is an error: In function `__aeabi_ldiv0': undefined reference to `raise' I think this has to do with floating point division used in the example. the makedefs file for stellarisware is set up to use software floating point. I'm using gcc 4.7.1 and it is set to use software fpu by default. Has anyone successfully built their own toolchain?
  15. If you are a Linux enthusiasts, you will love this! You can develop for the stellaris launchpad using command-line tools on Linux; check out: http://recursive-lab...etting-started/
