TMS320F2800157-Q1: Problem in linker command file

Aman, 

It seems to be an typo error in the linker command file. It should have been 0x088000 for the start address of the FLASH_BANK0_SEC_32 entry in the linker command.

FLASH_BANK0_SEC_32 : origin = 0x088000, length = 0x0400 /* on-chip Flash */
FLASH_BANK0_SEC_33 : origin = 0x088400, length = 0x0400 /* on-chip Flash */

Best Regards

Siddharth

Hi Siddharth,

Thanks for your response. Now I am getting error on these lines.

Let me what can I do for these.

Hi Siddhath,

The error is "#10099-D</a> program will not fit into available memory, or the section contains a call site that requires a trampoline that can't be generated for this section. placement with alignment/blocking fails for section ".cinit" size 0xf5 page 0. Available memory ranges: F2800157_flash_lnk.cmd /gpio_ex2_toggle line 112 C/C++ Problem".

I Found that only 130 KB of Flash is defined in the .cmd file.

Can you let me know any .cmd file where I can use the full flash for my code. I don't understand why these .cmd file are so full of errors.

Regards,
Aman. 

Aman, 

You can try to allocate the cinit sections across multiple sections similar to what has been done for .text section.

 .cinit           : >> FLASH_BANK0_SEC_112_119 |  FLASH_BANK0_SEC_120_127, ALIGN(8)

All the Flash sectors are mentioned in the linker command file and this is a generic file.

You need to change the linker command file to configure the memory allocation as per your use case.

Best Regards

Siddharth

Please tell me how to generate this .cmd file. Any training video or doc will be helpful.

Regards,
Aman.

Aman, 

If you want to create your own linker command file , you can use C2000 SysConfig Linker Command Tool.  Pls refer the following App note https://www.ti.com/lit/an/sprad49/sprad49.pdf

For getting an overview on the linker command file, pls refer the following link

Fixed the Flash errors.

Now I am getting error in RAM

Please let me know how this can be solved.

Aman.

This does not works.

Still Same error.
