Dear Sir or Madam,
I am encountering an issue while debugging a project using the TMS320F28374S microcontroller. During debugging, I receive the following error message:
"No source available for '_system_post_cinit() at D:\LLCDebugProblem\EVDP-UA603W0001_LLC_S0.01T25\Debug\EVDP-UA603W0001_LLC_S0.01T25.out:{3} 0x3fe493{4}'"
The compiler version used is TIv20.2.5.LTS. We have taken the following actions to address this issue:
- Switching the compiler version to TIv22.6.1LTS (with optimization level set to 'off') also resolves the problem and enables normal debugging.
Additionally, debugging can proceed into the main function; however, after initializing the EEPROM, just before initializing the Flash, the debug process encounters an error and cannot continue further.
I need assistance with the following:
- The root cause of this issue.
Currently, we speculate that our company's encryption software might be causing file parsing errors, and the newer compiler version (TIv22.6.1LTS) may have implemented isolation measures for these files. However, we do not have concrete evidence to support this theory. We sincerely request assistance from TI engineers.
Additionally, I have attached relevant screenshots of the settings for your reference.
Best Regards,
Cheng Yulong
