[u-boot] Net: smc911x: Invalid chip endian 0xc691c691 解决方案

After quick investigation, your issue might be related to a wrong configuration of the GPMC registers for the SMSC9118 chip.

The endianness test that fails in your case shows that the communication between the OMAP and the SMSC9118 chip is not correct. This test reads a register from the external chip that should always return 0x87654321, which is not good in your case. This is most
likely caused by bad timing configuration of the GPMC bus.*

Did you change anything in the U-Boot you are trying to run? If not then you most likely have a version that is not suitable for the revision of your board.
Last scenario would be a hardware failure of your board.我的板子就是因为网卡芯片没有焊接好吧 导致bus时序失败
