S32G2-VNP-RDB2 enable pfe2 in u-boot

chjc101 — Wed, 11 Aug 2021 03:48:04 GMT

hello,

In the Ethernet Enablement Guide for RDB2 board, We use the PFE_MAC2 port in Linux, but are we able to use this port in u-boot? When I connect the board and Windows PC and using bsp with pfe hardware, the u-boot always returns "APR Retry count exceeded".

I can use the gmac port in the BSP without pfe firmware.

1. is u-boot able to use pfe port?

2. can I use gmac port in u-boot when using BSP with pfe_firmware?

There are the output of u-boot :

1.When I am using BSP without PFE firmware, I could ping my PC using the GMAC port but PFE2 port.

2.When I am using BSP with PFE firware, I am not able to ping my PC using GMAC port or PFE2 port.

Can you please provide the full output of u-Boot "printenv" command executed immediately after an unsuccessful ping? Please use your terminal software logging capability and provide the output in the text format rather than a screen capture.

Best Regards,
Platon

Hello Platon,

I attach the text file inculding the output of printe command. I am using the BSP with PFE firmware and plug the cable into u58 and u84 port separately.

Best regards,

Richard

Hello Platon,

I find that by changing variable ethact from eth_pfeng to eth_eqos could solve the gamc problem.

Then the question is how to solve the "ARP Retry count exceed" problem when using PFE2 port.

Best regards

Richard

It seems that the three interface of PFEMAC0 could work, but PFE_MAC2 is still not work.
