Hi,
We have developed a snap-in board using the LS1023A QINQ CPU, which is shared between different models of devices. The board boots the uboot program from qspi, and the qspi flash size is 4MB. In addition, the board has an rgmii phy connected to the rmgii1 (EC1) interface of the CPU, which is used as a debugging network port.
Recently we produced device B, we use lsdk-1803, on the basis of ls1043ardb directly modify the adaptation and debugging uboot.
Debugging process encountered problems: debugging network port directly connected to the debugging PC, the PC side of the network port shows link up, but from uboot ping debugging PC failed, prompting "ARP Retry count exceeded; starting again". After boot into linux, I ping the debug PC and it doesn't work. I can't catch any arp packets on the debug PC.
I have tried to enable or disable the rx delay or tx delay on the phy side, but nothing works.
Also, we had a uboot program on another device A, provided by a third party collaboration. Using this uboot on device B, the debug PC can be pinged from the debug port under both uboot and linux.
I'm now confused as to which direction I can take next to troubleshoot the issue?
Thanks!
