Other Parts Discussed in Thread: DRA829
we are use DRA829 SDK 8.0, it can execution Sciclient_pmSetModuleState function, Although success was returned, the actual setting failed.
After exclusion and testing, it is found that it is a problem with the link file. If both .bss.devgroup and .bss.devgroup defined by section are placed in the same area, the function of Sciclient_pmSetModuleState is success.

Looking at the official documentation of Ti, it is not found that .boardcfg _ data and .bss.devgroup need special placement.
I don't know why?Are there any special requirements for placement of the .boardcfg_data and .bss.devgroup section in the ti code of SDK package?
Thanks.
