Linux/AM5728: PRU Ethernet issue

sfloat s
Intellectual 410 points
Part Number: AM5728


Tool/software: Linux

we have 5 same  custom board base on am5728. on our custom board, we want to use prueth ports as general 100Mbps ethernet interfaces.  We use the linux-rt-4.4.4, the prueth work well on 3 board, the other 2 don't work.(the 2 board can recognize prueth, but cann't ping with host.)  When we change the kernel to linux-rt-4.9.69, all the 5 prueth work well.

The pru code(am57xx-pruX-prueth-f) are different  on linux-rt-4.4.4 and  linux-rt-4.9.69. so we replace the pru code of linux-rt-4.4.4 with linux-rt-4.9.69, the prueth still don't work.

when the prueth don't work, the power off command work not well too.

Could some one give me some advices, please?

The dmesg on linux-rt-4.4.4 is :

    Hi,
    You are mentioning that you are using 2 different kernels, and if I understand correctly the 4.4.69 kernel the PRU eth is working as expected. Can you use the 4.4.69 kernel?

    Concerning the ping from eth2, there is not an ip address on eth2. While eth2 is showing a link detected status, the interface is not getting an IP address because either the DHCP process is either not working correctly or a static ip address has been assigned yet. Are there any messages in the boot log indicating an attempt to complete the DHCP process for eth2? Could you please attach a copy of the boot log? Also please do not paste the boot log directly into the post, it will make the post very log.

    Best Regards,
    Schuyler

    hi,Schuyler:

        Thank for you reply!  yes, we using 2 different kernels, and the 4.9.69 is work well. In the 5 board  the  2 board prueth  don't work when we use the 4.4.4 kernel. the 3 board work well and the 2 board work not well, we want to know why.

         Before ping host with board, we configure the eth2 ip use ifconfig eth2 192.168.2.10.  the boot log is:
