Thanks everyone for the feedback on the terminal programs. New problem with crossworks. I'm trying to redefine __putchar() to send out the SPI port, instead of to the virtual terminal. So according to the instructions, I should just be able to redirect the linker to use my function instead of the __putchar() function, right? I did this: -D___putchar=_my_putchar in the additional linker

I am seeing the linker place code for one module in a location that another module has reserved with the DS directive.

I am new to CCS and TI MSP430. Have used Keil compiler before. I am trying to use a bootloader in C which can get data from a serial port and update the Flash with application code. I did this in Keil toolset by using simple linker commands to locate the App. code at always the same address. The bootloader copied the new code to this address and then could be signaled to jump to it.. I h...

I am trying to reserve space in one project to allow for a large table to be programmed in another to remain in the Flash. I have successfully put the table where I need it to be using segments and the Linker Script. But I have not been able to make the primary project not overwrite the space. Below are the relevant areas of the linker script. I also have told the debugger to "Retain Unchang...

Does anyone know the purpose of the .sfr files in the 430/config directory (same directory as the linker command files?) The only mention of them that I found in the IAR documentation is that they are there. I noticed that the .xcl files do not define segments for non-initialized absolute data, does the linker use these files to define the DATA16_AN segment? Thanks in advance. Chris ...

OK, so I posted about __no_init and __data16 last week, but now I need to know how to locate variables into an absolute address. The TI CCS has an additional linker file which is used to locate variables for the USB data structures at an absolute address: /************************************************************ * USB linker cmd file ***************************************************...

Having accidentally erased the calibration values from INFOA Flash. It sounds simple enough, that for simple convenience I'd ideally like to be able to restore the values I was careful enough to write down (for the ONLY board I'll be using), as a conditional build option. However, there appears to be a linker segment clash, I can't figure out how to avoid. It works links with predicta...

I'm struggling to get started with msp430-gcc (on a Ubuntu 9.04 machine) as a cross-assembler/linker with target of msp430. I do not intend to use an IDE (no eclipse can be used as access to my development system is solely via ssh/telnet), so all is happening at command line. Source code is MSP430 assembly language (my target is MSP430F1232) and expected output from assembly/link is intel hex form...

I am using a BSL_Scripter to update the code on a 5438. One of the commands is the CRC_CHECK and the sample script passes the expected CRC. How do you compute the CRC of the code? Or can you find the CRC from the CCE V3.1 linker output? ------------------------------------

Hello MSP430 Developers, are there any new issues regarding this topic? I tried to change and run the example code available for IAR to CCE, but except a bunch of linker errors and unreferenced identifiers nothing worked out... Can someone help me/us out or provide further informations? Best regrads, Mitch --- In m...@yahoogroups.com, Meuse Nogueira wrote: > > Dea

Hello! I am using a F2254 with a standard TI board. I have created a new workspace and project, and set up the project options (Device = F2254, FET debugger and so on). I am trying to run a simple program (i have chosen an interrupt based LED blinker, msp430x22x4_ta_01 from slac122 (may be wrong on this number, but it is the IAR version anyway). It compiles at once, but I get the followi...

Hi, this is my first post in this group. I started to work for the first time with MPS430 about two weeks ago. I received some code originally written for IAR Compiler, and my first task is to make it run by using CCE Compiler. During this migration I have found that, beside all the necessary changes regarding proprocessor directives, intrinsics, memory allocation, compiler/linker opti...

I'm working on a program with the MSP430F417 using IAR. The program has two ISR's - one for a software defined UART using TimerA and the other a RTC using the BT. For both of these programs I used the sample code provided by TI to get me going and they both work fine - individually. The problem I'm having is when you combine the two programs I get a linker error saying " Error[e124]: Segmen...

I'm programming an MSP430x149 using IAR compiler. I'm not able to avoid the INFO block (0x1000-0x10ff) to be initialized at 0xFF when the program is uploaded. Any suggestion? (I removed the fill unused memory option in linker table, I declared a _no_init char array[0xff] @0x1000, no results...) Thank you, Giorgio ------------------------------------

Hello all, I have sampled a handful of the new MSP430F471xx chips, and I can't get the first one to program. I am getting tempted to remove the chip and try another from the sample bag.......but what are the odds of pulling a bad chip? I have all of the proper linker files ect. But everytime I try to flash I get "communication error, please connect the device and press retry". I'm stumped...

Hi guys, I need to do some optimisation on a piece of code and wanted to try out the profiling functionality of EW. Now I activated it like in the manual. This means: - C/C++ Compiler: Output> Generate debug information - Linker: Format> Debug information for C-SPY - Debugger: Plugins> Profiling I can now start and stop the profiler by its on/off button. But when I start my application it e

Hi, i am currently developing a module that replaces a function in flash by a new one recieved thru UART.The problem i am facing is dat before doing a block write i have to erase the segment which contains many more functions,even though i have modified the linker file to place my replaacble function in a seperate segment the erase command erases the entire segment which is 512 byte.M

Will the IAR ICC430 compiler/linker etc overlay variables? I have some significant RAM buffers that are not used simulataneously and their contents do not need to be preserved across function calls. Some decent compilers I have used would overlay such variables (unless I told it otherwise). I can't seem to get the IAR system to does such a thing. Is it just me or is this toolset prett
