HI:

参考Jetson AGX Orin Series Modules Tuning and Compliance Guide，Ethernet Compliance Test Guide，实际操作，寄存器修改未起作用

Is there any error from dmesg when you do the devmem?

4

no error.

kern.log (32.8 MB)

5

Are you sure you don’t see any error there or just because you shared out a 32MB log which is not possible to find out the error…

6

不好意思，上传错了

kernel.log (77.5 KB)

What is the issue? Are you using something to generate traffic on RGMII? For creating traffic on the Orin RGMII interface, software (for example, iperf, Ping, SCP) or traffic generator hardware is needed.

galbot@galbot-echo:~$ sudo busybox devmem 0x02318804
0x20010000 这个寄存器设置读出来和写的不一样，没有关系吗？这边用仪器测试出来，波形不对

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

The readback value could be different from written value and is expected and it may not be an issue here. Could you attach the waveform and explain why you think it is wrong?
