Hello

I am facing an issue to generate a2l file with elf file as input.

Elf file is generated with CodeComposerStudio and C2000 compiler v22.6.1

If I load elf file in ASAP2 Studio (from Vector) to generate a2L file I can see that addresses are different compare to .map file. In fact they are *2:

From .map file

From .out file (elf) loaded from ASPA2Studio:

When I use debugger, addresses are conform with .map file.

I was wondering if this was a known issue or if it can be due to bad settings during build.

Thanks for your support,

... but my guess it presumes the smallest unit of memory the target system can access is an 8-bit byte. This is not the case for C28x. The smallest unit of memory a C28x CPU can access is a 16-bit word. For more details, please see the article Byte Accesses with the C28x CPU.

Thanks and regards,
