I recently buught 5 orange pi r1 plus lts, for use in a simple SNMP server, the controlled board will be on the LAN porta and the WAN port will produce the SNP server.

I was working fine with the Openwrt 21.02.1 a couple of days, but today the YT8531C stoped working without any chance to go up.

I try to connect with "Ubuntu Image updated:2021-11-29" from the website and I couldn't get the interface to work|. I produced this System diagnosis http://ix.io/3IXA

I tryed with the "Openwrt updated:2021-11-29" and compared the dmesg with another "r1 plus lts"  and the difference in dmesg are messages like this:

board that is working:
  1. ....
  2. dwmmc_rockchip ff500000.dwmmc: All phases work, using default phase 0.
  3. ....
  4. dwmmc_rockchip ff500000.dwmmc: Successfully tuned phase to 210
  5. ....
  6. rk_gmac-dwmac ff540000.ethernet eth0: Link is Up - 1Gbps/Full - flow control rx/tx
Copy code
board that is faliling
  1. ...
  2. dwmmc_rockchip ff500000.dwmmc: Successfully tuned phase to 91
  3. ....
  4. dwmmc_rockchip ff500000.dwmmc: Successfully tuned phase to 121
  5. dwmmc_rockchip ff500000.dwmmc: Successfully tuned phase to 121
  6. dwmmc_rockchip ff500000.dwmmc: Successfully tuned phase to 121
  7. dwmmc_rockchip ff500000.dwmmc: Successfully tuned phase to 91
  8. ....
Copy code
and this board keep jumping between 121 and 90.


Do you have any idea how can I continue debugging or reapair the interface? Any channel to get support for the board?

Best regards
