Hi,
My customer has been having continued issues with the PCIe connection to PC with regards to the two issues below:
1) Link-up stability
2) LTSSM training within PCIe base specifications
I've linked three relevant E2E threads we've previously set up before and the solutions we offered them with the help of E2E.
- AM5706: Cannot connect AM5706 as PCIe End-point to the PC as PCIe Root Complex: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1041657/am5706-cannot-connect-am5706-as-pcie-end-point-to-the-pc-as-pcie-root-complex
- AM5706: PCIe Reset Specifications Not Met: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1046195/am5706-pcie-reset-specifications-not-met
- AM5706: Setting PCIe De-emphasis and Voltage Amplitude: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1045835/am5706-setting-pcie-de-emphasis-and-voltage-amplitude
However, they are still having issues with achieving link-up stability and the 20ms LTSSM reset specification.
What could be the possible issue as to why they're struggling with the connection and the LTSSM training? Any other possible solutions would be wonderful.
Best regards,
Mari
