Hi Arslan,

Thanks for performing this test.

We noticed the BSP you did your testing with was named the "a10gx" BSP. If this BSP is unaltered then it does not contain any channels and whilst the compiler may have passed rtl generation it will probably fail later on in the compilation process. However, the Intel "a10gx_hostpipe" BSP does contain IO channels and we were able to recreate the bug/error with his BSP. Attached is modified kernel code and compilation output

Could you please try the BSP with the IO channel and verify you can replicate the issue?

Thanks,

Gildas
