Cant boot DietPI from emmc

#1

Hi All,

I am new to the forum and this is my first post!

I am having trouble getting my Radxa Zero to boot DietPI from EMMC. It will boot fine from SD, I have tried various guides from the Radxa wiki with no luck.

Below i have detailed the commands from my most recent attempt all of which complete successfully, any help would be greatly appreciated.

Note: I also attempted the winwoze approach with balena etcher and RZ_USB_Boot_Helper_V1.0.0 ETC.

Thanks,
Adrian

wget https://dl.radxa.com/zero/images/loader/radxa-zero-erase-emmc.bin
wget https://chewitt.libreelec.tv/testing/u-boot/u-boot.bin.sd.bin-radxa-zero
wget https://dietpi.com/downloads/images/DietPi_RadxaZero-ARMv8-Bullseye.7z
7z -x DietPi_RadxaZero-ARMv8-Bullseye.7z

insert usb and hold boot button

sudo boot-g12.py radxa-zero-erase-emmc.bin
sudo dd if=DietPi_RadxaZero-ARMv8-Bullseye.img of=/dev/sdb
sudo dd if=u-boot.bin.sd.bin-radxa-zero of=/dev/sdb conv=fsync,notrunc bs=1 count=444
sudo dd if=u-boot.bin.sd.bin-radxa-zero of=/dev/sdb conv=fsync,notrunc bs=512 seek=1

remove usb then plg rz into monitor keyboard and power. No Boot!

i get the following in serial console which i believe is from u-boot. looking at the message EMMC:0 I would say there doesn’t appear to be a boot image for emmc ? I have no experience of u-boot so not really sure what i’m looking at or how to resolve the issue.

Any help much appreciated. Thanks in advance.

Does DietPi not have a u-boot binary baked in? For most OS images you only have to flash the one image and you should be good to go.

EDIT: Also, your last dd command is missing the of= parameter.

Thanks for the reply, i just forgot to detail the “of=/dev/sdb conv=fsync,notrunc”. i have updated initial post.

#5

My first attempt was to just flash the DietPi image with balena. this did not work.

I have included a full extract of the serial console on boot attempt below and above that a snippet which i believe may relate to the issue, I am using a fairly beefy usb phone charger so don’t think the issue would be power related.

Try wiping and flashing the DietPi image by itself again, and if you get that same boot error, try power cycling until it boots. There was a bug in U-Boot that caused that error sometimes. DietPi might not have the patch that fixed it.

#7

Still nothing sadly. not sure what to do now.

#8

I have created a thread on the DietPI Support forum, will see what comes of that. Thanks for all the help.

#9

How many times did you try power cycling? I’ve had to do it 10+ times in a row before. Sometimes it helps to let it sit unplugged for 15 seconds or so before trying again.

#10

I tried a load of times before, i just gave your approach a go with no luck. I’m not really sure why it would be necessary to do this or why this would allow it to boot.
