Edge2 Uboot UEFI

We recommend start 1st partition from 32768 block

sfdisk --dump /dev/mmcblk0 | grep -e first -e start=
first-lba: 32768
/dev/mmcblk0p1 : start=       32768,

UEFI bootloader for Edge2 can be fixed/updated via OOWOW Online Scripts

UEFI bootloader for Edge2 can be installed via OOWOW online images

Problems was solved: solution, after we can start EFI loader and boot up next system

eMMC storage From 16384 to 32768 block must be reserved for boot-loader

Default Boot problem

OOWOW SPL loader can't find FIT-image at 0x4000 sector eMMC | SD

Solution

Write FIT image to eMMC or SD 0x4000 sector

write-uefi-bootloader-to-emmc

EFI=edge2_UEFI_Release_v0.7.1.img
wget https://github.com/edk2-porting/edk2-rk3588/releases/download/v0.7.1/$EFI
DISK=${DISK:-/dev/mmcblk0}
dd skip=2048 seek=$((0x4000)) count=$((0x4000)) of=$DISK if=$EFI conv=fsync,notrunc

For example 1st write https://dl.khadas.com/.test/edge2_UEFI_Release_3676af4b.img to USB flash, start OOWOW going into shell…

copy FIT image to eMMC

dd if=/dev/sda skip=2048 count=$((0x4000)) seek=$((0x4000)) of=/dev/mmcblk0

or just using oowow with Internet, start OOWOW going into shell…

oowow copy EFI loader to eMMC

root@edge2-00000:/# curl -jkL \
 https://dl.khadas.com/.test/edge2_UEFI_Release_3676af4b.img \
 -r$((2048*512))-$(((2048+3440)*512)) | dd seek=$((0x4000)) of=$(mmc_disk)

check eMMC EFI Image header

root@edge2-00000:/# dd if=/dev/mmcblk0 skip=$((0x4000)) count=1 2>/dev/null \
| hexdump -C | grep "00000080  49 6d 61"

check eMMC

root@edge2-00000:/# dd if=/dev/mmcblk0 skip=$((0x4000)) count=1 | hexdump -C
