===== Edge2 Uboot UEFI =====

<WRAP important >

We recommend start 1st partition from 32768 block

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

</WRAP>

<WRAP tip >
UEFI bootloader for [[:Edge2]] can be fixed/updated via [[/software/oowow/how-to/online-scripts]]

</WRAP>

<WRAP tip >
UEFI bootloader for [[:Edge2]] can be installed via [[:OOWOW]] online images
</WRAP>

<WRAP tip >
Problems was solved: [[#solution]], after we can start EFI loader and boot up next system
</WRAP>

<WRAP alert >
eMMC storage From **16384** to **32768** block must be reserved for boot-loader
</WRAP>


===== Default Boot problem =====

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

```log OOWOW SPL boot log

U-Boot SPL board init
U-Boot SPL 2017.09 (May 12 2023 - 11:40:17)

Trying to boot from MMC1 :: 0
Trying fit image at 0x4000 sector
Not fit magic
...
```

===== Solution =====

Write FIT image to eMMC or SD **0x4000** sector

```sh 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...

```sh 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... 

```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)
```

```shell 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"
```

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