Sorry for stupid question. I tried install the instruction on my rock 3a (different board, but similar). rock-3a:~:% uname -r 6.1.11-rk35xx rock-3a:~:% ls /dev/mtdblock0 /dev/mtdblock0 I choose option: "Boot from MTD Flash - system on SATA, USB or NVMe". It does not work. (solved usb-flash bug) Now, load from USB-flash not working. When I take out the SDcard, the system will not boot and the blue LED is on continuously rock-3a:~:% df Filesystem 1K-blocks Used Available Use% Mounted on tmpfs 787664 9260 778404 2% /run /dev/sda2 29124480 2041448 25578216 8% / tmpfs 3938308 0 3938308 0% /dev/shm tmpfs 5120 4 5116 1% /run/lock tmpfs 3938308 0 3938308 0% /tmp /dev/zram1 47960 4284 40092 10% /var/log tmpfs 787660 0 787660 0% /run/user/1000 rock-3a:~:% blkid /dev/mmcblk0p1: SEC_TYPE="msdos" LABEL_FATBOOT="armbi_boot" LABEL="armbi_boot" UUID="5F4E-9DB1" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="bootfs" PARTUUID="651eafa5-90c1-b34a-88be-6db5e1c4611c" /dev/mmcblk0p2: LABEL="armbi_root" UUID="6ce28e93-ed91-46ae-9035-701bfe34a5fd" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="631abe0e-026d-4f46-a209-65697a9d40e9" /dev/sda2: UUID="c5b2342e-c45a-49ce-9039-7670e6627166" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="329b8277-78bb-3d46-bd0a-fdfb8c76629d" /dev/sda1: SEC_TYPE="msdos" LABEL_FATBOOT="armbi_boot" LABEL="armbi_boot" UUID="5F4E-9DB1" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="bootfs" PARTUUID="651eafa5-90c1-b34a-88be-6db5e1c4611c" /dev/zram0: UUID="96093c4c-52ef-4482-9b77-b78a24cdf555" TYPE="swap" /dev/zram1: LABEL="log2ram" UUID="4970e224-e849-4923-bdbd-99584839f39b" BLOCK_SIZE="4096" TYPE="ext4" /dev/mtdblock0: PTUUID="ce22cf47-be9f-48cd-8ff4-cba055568687" PTTYPE="gpt" Any ideas

thx the user-led is correct path. i used "none" to turn off LED, it's work for me echo none > /sys/devices/platform/leds/leds/user-led/trigger

Hi. I use Armbian 22.05 Jammy Kernel 5.17 on my rock 3a. The blinking blue is very annoying. How can i stop this LED?
