TMS320F280025C: TMS320F280025C

Please zip up these files ...

• executable .out file
• linker map file
• hex2000 command file with the ROMS directive in it

Attach that zip file to your next post.  Also show the exact command used to invoke hex2000.

Thanks and regards,

Hi George,

Thanks so much for your quickly replay. Attached is zip file that include all your request.

The the exact command used to invoke hex2000 as follow:

command: "${CG_TOOL_HEX}"

pattern: ${command} ${flags} ${output_flag} ${output} ${inputs}

Post build step:"${CCE_INSTALL_ROOT}/utils/tiobj2bin/tiobj2bin" "${BuildArtifactFileName}" "${BuildArtifactFileBaseName}.bin" "${CG_TOOL_ROOT}/bin/ofd2000" "${CG_TOOL_ROOT}/bin/hex2000" "${CCE_INSTALL_ROOT}/utils/tiobj2bin/mkhex4bin"

Please let me know if you need any more documents.

Thanks

John

Thanks George for your replay.

According to your suggestion, I cut post-build step, but the CCS can not generate bin file. I look back this earlier thread on this topic, you did spend some time with me at that time, and give me some solution. I try to re do that, because I fixed the bin size issue with myself solution at last time. I found I can not set ROMS directive correctly because I got error message:
<Linking>
"../28002x_generic_flash_lnk_V4.cmd", line 52: error #10008-D: cannot find file "ROMS"
"../28002x_generic_flash_lnk_V4.cmd", line 52: error #10021-D: expecting filename, option, MEMORY, or SECTIONS instead of "{"
"../28002x_generic_flash_lnk_V4.cmd", line 54: error #10043-D: expecting "";"" instead of "}"
error #10010: errors encountered during linking; "DS3_280025_20220824_Rev1_V5_T57R11F18_t1.out" not built
I add ROMS directive at my .cmd file:
ROMS { //line 52
all_mem: o = 0x106040, l = 0x19fc0
}
This is why I did not use this at last time.

My CCS setting is suitable for 280049 chip, which produces 70KB bin files, and sometimes 70KB bin files for 280025 chips, but now produces 1033KB bin files. The problem seems to be related to the program size of my design. My current program size for LS RAM is around 90+%. That's where I get confused.

Please let me know how to set ROMS directive, I can not find this at TI webpages.

Thanks

John

The ROMS directive does not go in the linker command file.  Instead, it goes in a separate command file that is an input the hex utility hex2000.  For a better understanding of image mode and why that requires a ROMS directive, please search the C28x assembly tools manual for the sub-chapter titled Image Mode and the --fill Option.  Note you do not need to use the --fill option.

Thanks and regards,

Great, I will take look it.

Thanks

John

Hi George,

I read the doc of the  C28x assembly tools manual but I still can not let the ROMS directive work in my case. Do you know where I can find a example of ROMS directive in TI system?

Thanks

John
