Hello,
I have a problem of SRIO (DSP0<-> SRIO Switch <-> DSP1) interface in my PBA. The SRIO connection in my PBA is shown below.
- DSP0 (TMS320TCI6608CYPA)<-> SRIO Switch (TSI578-10GILY) <-> DSP1 (TMS320TCI6608CYPA)
- 4x lane (SRIO_PATH_CTL_4xLaneABCD), 3.125 G
I'm trying to test interface between dsp0 and dsp1 to use the TI Ref code (KeyStone_SRIO).
I have modified TI Ref code to apply to my PBA. Then, I tested the internal loopback test (SRIO_DIGITAL_LOOPBACK, SRIO_EXTERNAL_LINE_LOOPBACK, SRIO_SERDES_LOOPBACK ) successfully. However, I failed the test (SRIO_NO_LOOPBACK, SRIO_EXTERNAL_FORWARD_BACK) unfortunately.
During the SRIO_NO_LOOPBACK or SRIO_EXTERNAL_FORWARD_BACK testing, I seems that the data from the DSP0 was not arrived at the SRIO Swtich, except for the control data.
Then, I send my test code for error debugging to korea FA
Sooner or later, Mr.jung will send my test code to you.
I want you can be going to point out a error of my test code. Then, I want to receive your code(reference code) for SRIO interface. (DSP0<-> SRIO Switch <-> DSP1)
Please, I want you will reply quickly.
