Hi Kiran, OK, that makes sense! Safe designs all around. Thought I would check. Cheers and thanks for your help, Paul

Thank you for taking the time to provide additional insight. I view these posts as additional reasons to implement a change in the linker. I added them to CODEGEN-5079, which is still under review. Thanks and regards, -George

Hi Krishna, Can you add the attachment:) Todd

Hi Jared, What are your input design conditions? It is possible the min on-time or off-time limits might be limiting the frequency. Can you please share your design using the "Share Design" option with a public URL? Regards, Amod

thanks Chaster but this is not my case. Even in disassembly the breakpoints that are set using breakpoint menu on a symbol (e.g. function preloader_console_init()) do not work. Only simple ones that are set few commands ahead of the current instruction do.

[quote user="fmdhr"]I assumed that I have to do something like #pragma DATA_SECTION(pctf, ".bss_cla"); struct xxxx pctf; in a (e.g.) cla_data.c file and to use extern ... pctf etc. in the .cla file.[/quote] That is correct. Note, however, the pragma DATA_SECTION is optional. [quote user="fmdhr"]the structures (and vectors) now are aligned to page boundaries, wasting some memory[/quote] To understand that better, please see the article Data blocking in the C2000 MCU compiler explained . [quote user="fmdhr"]Since I set the preprocessor options for duc_cla_init.c as requested, it is marked with a little key in the project view. What does it mean and how to clear it ("restore default options" did not)?[/quote] Please see the File Specific Options part of the article on CCS Project Management and Build . [quote user="fmdhr"]Are other compiler versions affected too? (No, I am not keen on compiler updates, just good to know.)[/quote] Yes. All C28x compilers have this limitation. [quote user="fmdhr"]Please consider a users view: He adds/changes some data anywhere in his program. This may shift other data across a page border, and without any warning at a totally other place in a formerly well running part of the software an error rises (in my case, the controller still worked, but only in one direction). One kind of error IMHO most difficult to find.[/quote] You make a valid point. I made a similar point to the compiler development team. Thanks and regards, -George

[quote user="Igor Kordunsky"]Is this even possible to define memory block size in C or globally?[/quote] Yes. Define it in a header file. Then include that same header file in both your C code and your linker command file. Thanks and regards, -George

[quote user="Zlatan1988"]But the current version is supporting this, right? So what do I have to do to get the same hex-file? [/quote] It probably isn't possible. Equivalence between -mcpu and -mmcu is not specified, tested, or documented. [quote user="Zlatan1988"]I personally don't like this option[/quote] I understand. Nonetheless, the option -mcpu is going away. You need to change to using -mmcu. [quote user="Zlatan1988"]- What is the CPU_Bug with CPU19 :-)[/quote] I don't know. I suggest you start a new thread in the MSP430 device forum . Thanks and regards, -George

Just because you clicked those, it does not mean that they are being used. Which RTOS do you want? DSP/BIOS or SYS/BIOS?

Please send in this test case I requested earlier ... [quote user="George Mock"]Pick one of the error diagnostics you get. For one source file which gets that diagnostic, please carefully the follow the directions in the article How to Submit a Compiler Test Case . That will result in something I can build, and let's me reproduce that same diagnostic.[/quote] Thanks and regards, -George

Please let me know what you see that makes you think the text section is divided into two pieces. Thanks and regards, -George

Thanks. It's probably easiest to start with a simple DSP/BIOS example (build it and confirm it works and ROV does also). Then add you application code into the example. Todd

hi David thank you for your reply. I attached schemetic again. as you said. i also thought there is no relation between input rate and output tr/tf. but result was not. please look at and let me know if there is any fault. Regards. Woo HyungJe

Ki, OK - thanks for the update, John

I am only changing to --opt_level=3 avoids the problem. Why --opt_level=4 will cause the problem , I want to program smaller and run faster.

Hi, maybe you misunderstood my message - i DID used pragma retain , when i did not work i tried --retain in the linker file which did not work either. i have also placed the used attribute on the variable but it also did not help. basically nothing worked for global static variable except if i enable the --keep_unneeded_statics flag which is a global one and i want to address only specific variable. it seems the problem is with the compiler and the variable never reaches the linker stage but that is what the used attribute is for - to tell the compiler it should keep the variable - from some reason it does NOT work any advice?

Interesting, I was disappointed with your initial response and I ended up coming up with my own hack by setting: export TMPDIR=/tmp/${USER} export _JAVA_OPTIONS="-Djava.io.tmpdir=${TMPDIR} " I just noticed your follow up response and tested it and it works as well. Any chance they are actually going to fix the source code so that Code Composer actually works with multiple users like default Eclipse (or at least update the documentation to being either unsupported or including the recommended patch)?

So I took your advice and removed spaces and special chars from the folder and workspace and still getting the same error.
