omerdf posted a topic in GeneralHello, I'm using MSP430F5131 and trying to program it by IAR Embedded Workbench while using the MSP-FET debugger. A short background of the PCB: After i compiled the code in IAR with not errors found , i connected the MSP-FET to the MSP430 in a Spi-Bi-Wire connection according to the datasheet. The MSP430 is placed in a PCB which includes 12V input voltage and 2 regulators of 5V and 3.3V . The MSP430 I/O's are connected according to the datasheet (including external pullup resistors and capacitors) along with the Spi-Bi-Wire connections. I energized the PCB with a 12V supply voltage , connected the MSP-FET's connector to a Header connector on the PCB and the other side connected to the PC by USB. My problem is : In the IAR , once i try to download the code into the MSP430 (by clicking the 'Download and Debug' button) it says that it needs a firmware update , so i clicked ok and download the new update , but when it tries to initialize hardware i encounter the error : "Fatal error: Could not find device (or device not supported) Session aborted!" I have tried multiple things in order to find the solution - with no success . Does the AVcc and AVss needs to be connected even if i dont use any analog options? coz its not connected to anything. I also tried to download the program to the MSP430 with code composer studio but encounter the same error. Thanks in advance.
A short tutorial on how to use the IAR Embedded Workbench 5.3 to program and debug MSP430 microcontrollers on a windows box.The article teaches the reader to create and compile a simple C Project to blink the LED on a launchpad development board from Texas Instruments.The article can also be used with other MSP430 emulators like MSP430 Flash Emulation Tool (MSP-FET). IAR Embedded Workbench for MSP430 is a commercial integrated development environment developed by IAR Systems. The IDE comes in a paid full version and a code limited trial version.The free version can be downloaded from the IAR website free of charge and supports all the MSP430 derivatives. It is limited to a program size of 4KB.This would sufficient for programming most MSP430G2xxx series that comes with Launchpad development kit.
