Hi all,
We use four DSP(TMS320C6678) on a board(designed by ourself). The four DSP use SRIO to exchange data with a PPC. The system work after a period of ime, the PPC find that the SRIO data from the DSP stoped. I want to check the DSP SRIO module status , so I use the Spectrum Digital XDS560v2 to stop the four DSP, and read the SRIO module register. But when I access the SRIO register(0x0290B154), the register is all zero.The result is as below:
But when I access SRIO_SERDES_STS(0x02620154), I can read a value 0x0C183061, the result is as below:
The four DSPs are all the same situation. In my opinion, the DSP SRIO module may have collapsed. But I don't know what will cause this situation. If anybody has some experience about this situation, please share with me.
Best Regards
