Write FIT image to eMMC or SD 0x4000 sector
For example 1st write https://dl.khadas.com/.test/edge2_UEFI_Release_3676af4b.img to USB flash, start OOWOW going into shell…
dd if=/dev/sda skip=2048 count=3440 seek=$((0x4000)) of=/dev/mmcblk0
or just using oowow with Internet, start OOWOW going into shell…
