  1. msp430.xmsp430.xI have modified the scripts in a memory.x file and an msp430.x file, and I want the linker to use these scripts instead of the default linker scripts. I have used the modified msp430.x to replace the msp430.x file in C:\energia-0101E0016\hardware\tools\msp430\msp430\lib\ldscripts, and I have used the modified memory.x file to replace the memory.x file in C:\energia-0101E0016\hardware\tools\msp430\msp430\lib\ldscripts\msp430f5529. I know the latter file is being used, because its absence causes a "can't find file" error during compilation. The absence of an msp430.x file, on the other hand, does not cause such an error. Symbols I have defined in the msp430.x file give me "undefined reference to..." errors when I try to use them in my source code. How can I be sure that my modified msp430.x file is being used by the linker? I'm using an MSP-EXP430F5529LP LaunchPad with an MSP430F5529 processor and with Energia v. 16. Attached are the simple test file I am trying to compile and the modified script files with changes to allow creation of an exclusive flash_data section in nonvolatile memory. The verbose compiler output is as follows.

  2. 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.
