Hi @Werner! I configured the 6.1 kernel (manually added an RT-patch too), but I have problems booting it, it only detects mmcblk0boot* partitions from my card and no rootfs/user partitions.
My uboot is a slightly modified old rockchip-uboot of 2017. Does kernel 6.1 require a newer uboot? If so, which one should I take?
Nevermind, my bad! I've missed a CONFIG_EFI_PARTITION...
@Seihan, sorry, I cannot use 6.6 for some reasons, only 6.1 and below, so I can't be any of help
