Good morning gentlemen, I have just discovered that one of the cores on my RockPi4B is faulty and often causes segfaults and crashes, I can disable the suspect core by issuing the following command $ sudo echo 0 | sudo tee /sys/devices/system/cpu/cpu2/online However, this is fine if the machine has booted, but i want to disable the faulty core as early on in the boot process as possible. Is it possible to disable the core in the uboot environment, or could someone offer me some advice as to the best time to disable the core? Thanks, Leon.

When I posted that, the script didn't check to see if the uboot file was there. Apparently it's all fixed now.

Ok, next issue... When booting from eMMC the sdcard reader is not usable for some reason.

OK, the script runs fine, except the uboot file was missing, I compiled it from source easily enough. this is orangePi Plus version download here https://mega.nz/#!nEhzARbL!b4GCocqV_DlikufwdB_ajrSFwIjF1QS5BA57K0MCbm4 flash with $ sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/mmcblk1 bs=1024 seek=8 immediately after running $ sudo nand-sata-install Thanks so much Igor, love your work.

so what needs to be enabled in the kernel(legacy) to allow emmc install? can I keep my current rootfs? as I have it set up as I want it to be.

Is it possible to install armbian to EMMC? Is the Fat32 partition still necessary?
