F2812 TMS320C28xx : One or more sections of your program falls into a memory region that is not writable.

Hi Kevin,

This means in your linker cmd file you are using some memory address which are either read only or invalid for the device you are using. Please check your linker cmd file to make sure all the address are valid and read/write type.

Vivek Singh

Sorry I'm still very new at this. Please bear with me. Is .cmd the linker file?

Yes, .cmd file is linker file.

Hi Kevin,

Since you are just getting started with C2000 please check-out the Getting Started with C2000 Wiki.  The workshops are great reference to the entire code generation process:  compile, link, and loading into RAM and/or FLASH.

Currently I have 2 linker files:
DSP281x_headers_nonBIOS.cmd and F2812.cmd

Is it normal to have 2 linker files?

And by the way this is off topic but is it possible to have direct Skype contact with you? I'd appreciate the help

Hi Jeff,

Thanks for the link, I'll definitely check it out

Meanwhile, what do I have to do with the linker files if it generates that error? I thought linker files is originally from TI not user-made

Hi Kevin,

You can have multiple CMD files, the DSP281x_headers_nonBIOS.cmd associates symbols with the memory-mapped addresses of the device peripherals and the F2812.cmd defines the memory of the devices and maps the sections in your software to this device memory map.

Please see the following link for useful references: e2e.ti.com/.../56869.

If you want to connect with me directly, you can provide me your contact information on the forum or via a private message (connect and then private message is an option).

Hi Jeff,

I think that link is dead. Also I'm still browsing through all the guide but my goal now is to get pass this problem.

What I confused of: so, do I have to change the linker file? Because it's using some of the memory address that is invalid right?

Any suggestions of what I should do next?

Hi Vivek,

Any advice on what I should do next? Do I have to edit the linker file? It seems dubious since I got the file from Code Composer itself

Kevin,

I think in CCS3.3, if you are trying to load code to Flash, you have to use the On-chip Flash GUI (I think it is available in CCS Tools menu in CCSv3.3). You can not use 'load program'.

Kevin,

Can we close this thread? If your issue is not resolved, I can ask our F2812 Flash tool expert to look in to this. Let me know.

Thanks and regards,
Vamsi

Issue hasn't been resolved.

I asked another question but still got no reply

Further help needed. Thank you

Kevin,

When you say another question, do you mean the question (in this thread) regarding editing the linker command files that TI provided? Or Are you referring to a different post?

Regarding the linker command files: Don't edit the linker command files yet. First, try to load the Flash using the On-Chip Flash GUI. Did you try the On-Chip Flash Plugin and still got the same error?

Thanks and regards,
Vamsi

I'm referring to the same post

Yes I never edit the linker command and I got the same error. I'm trying to debug the code using breakpoint instead of flashing it then test my new code since it's so time wasting. And yes I tried the On-Chip Flash Plugin and still got the same error

Thank you

Kevin,

Can you try to use CCSV6 instead of CCSV3.3?
It will be easy for us to get you support help for newer versions of CCS.

Thanks and regards,
Vamsi

I actually tried CCS 6 before CCS 3.3 but I was having a hard time importing the old *.pjt file and all the linker file

With CCS 3.3 I just need to import *.pjt and everything's there

Any advice?

Kevin,

In CCSV6, did you try using 'Import Legacy CCSV3.3 projects' under 'Project" menu in CCS Edit view?

If not importing your CCSV3.3 project in to CCSV6, did you try to load the coff file using CCSV6?

Thanks and regards,
Vamsi
