TMS320C6678: how make pdk NIMU example to works with sgmii0 instead of sgmii1

Part Number: TMS320C6678


hello

we are using "ti-processor-sdk-rtos-c667x-evm-06.03.00.106" which is latest TI-RTOS release for 6678 processors. also we are using CCS 10.3.

we use PDK 2.0.16 to build "NIMU example". also we were aware to use suitable compiler version which is bundled with RTOS package (version 8.3.2) instead of CCS 10.3 latest compiler.

we have a custom board which contain two DSPs. in one of them sgmii1 is connected to PHY and we can successfully run NIMU example on this DSP. in second 6678 DSP, it is sgmii0 that connected to PHY and we have lots of problem to get NIMU example working for second Ones. we have searched e2e forums and it seems lots of people have solved this issue but most of them were using old NDK 2. we are using NDK 3.61.1 (from TI-RTOS 06.03.00.106) and most of those solution doesn't seems to work with new NDK release.

which part of NDK or NIMU source code we should modify to get that example working for sgmii0 instead of sgmii1?

thank in advance
