When I configure pcie C9, the system cannot start properly

Mar 04, 2024

hello:

Our self-developed carrier board is connected with an i210t phy on C1, C7 and C9 respectively.

After I set up pcie c9, my system cannot start normally. Please help me analyze the cause.




  The system startup log is as follows:

502.log (104.5 KB)


  I modified it by following the link below:
p3767.conf.common I made the following changes in the file
127 #add by bxl config #1

128 #ODMDATA=“gbe-uphy-config-8,hsstp-lane-map-3,hsio-uphy-config-0”;

129 config #2

130 ODMDATA=“gbe-uphy-config-9,hsstp-lane-map-3,hsio-uphy-config-0”;
