Hello,

I'm currently working on a custom board with LS1043a. This board has the following connection:

chcmedeiros_0-1645458981236.png

We are using Uboot 2020.04 and Linux  5.4.47. Our serdes protocol is 0x3555.

At this  point we are able to ping an external PC on Uboot (the SERDES PLL reset was necessary), but when reaching Linux we are not able to ping an external device (even when we re-send the PLL reset command), not sure if this is a device tree problem.

I added in the attachments my device tree, uboot log and kernel log, if someone had a similar concern and can give me any hint.

Please provide connection schematics as PDF and measured frequencies of the SerDes reference clocks.
