hello,help me !
my boadr is t4240 Custom board, I developed with sdk1.9, Now the kernel is stuck after uboot loads the device tree, Here is log:

It's stuck at the kernel jump entry, Are there any bugs in t4240 startup that need to be fixed ?
I modified the bug according to the following, but my problem is still not solved
