hello,
I'm asking a question because I couldn't find the answer I was looking for even after searching the existing forums.
SDK: 06.03.00.106 (k4.19.94 LTS)
The existing 4.4.19 kernel was used and updated to 4.19.94.
uboot uses the existing one, and only the kernel has been updated.
However, after the update, eth0 works, but eth1 does not.
Tested on the same board.
eth1 operates normally in the existing kernel, but does not operate in the new kernel.
