IP1001C Ethernet PHY not working with Jetpack 5.0.2

Dear nvidia team:
Our phy IP1001C has no any problems with Jetpack 4.6 and lower. However, with Jetpack 5.0.2, we found a problem:

  1. Connected with 10/100M switch, the network status is correctly.
  2. Connected with 1G switch, the network becomes unstable and then disconnected. But there is no any errors in kernel log.

Do we need to modify any configurations?

If you need futher information, let me know.
Thank you

Sorry for the late response, have you managed to get issue resolved or still need the support? Thanks

I still need to be supported. Thanks

Not sure if that’s driver support problem on Kernel 5.10, need to check with internal team if any experience to share.

OK, Thanks very much.

Hi,

One question here. Are you filing the issue in wrong forum? Xavier NX cannot change PHY.

Because there is no any problem in Jetpack 4.6. However, after upgrade to Jetpack 5.0.2, this problem arose. So I think Nvidia Team may be able to provide some solutions.
Thanks

No, my point is are you asking this issue on AGX xavier or something else…

This is “NX” forum. Not “XavierAGX”…

我的意思是你這個topic是不是發錯地方了…

ok, so this is on AGX Xavier ,right?

Hi,
Sorry for late response. Yes, this is on “AGX Xavier”.

14

Did you ever enable the PHY driver for IP1001C in kernel?

15

Yes, already enabled.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Hi,

Could you share the result of
