@baibaidashixiong @loongson-zjl @yetist did your meet this?

[yetist]

Why is the kernel version here 4.19?

[DengkeDu]

I get a 4.19 kernel from loongarch team, the yocto master branch kernel version was 6.5, can't boot on 3A5000

[DengkeDu]

Why is the kernel version here 4.19?

can you provide a kernel that can boot on 3A5000? thanks!

[DengkeDu]

Why is the kernel version here 4.19?

when I switch to yocto master branch linux kernel, show:

EFI stub: Booting Linux Kernel...
EFI stub: Exiting boot services

ending ....
