Trying to figure out whats wrong with my radxa zero

#1

hey guys im trying to figure out what’s going on with my radxa zero. i’ve tried to reach out by using the “contact us” on the website. anyways heres whats going on. the first day i got the radxa zero i followed the guide and was not able to immediately clear the emmc. after some time i was able to clear it and install the ubuntu os on it, but when i tried to turn it on, i had no output from the micro HDMI port. so i tried to clear it again, now i get nothing. after i clear the emmc as per the guide, it doesn’t show up as a usb storage. here is my output from lsusb
lsusb :

it shows its there but when i use lsblk or fdisk -l its nowhere to be found.

any help would be much appricated, if i have to buy another board because this one is done for, i dont mind i would just like to know if its a software, hardware, or a me issue.

Bookmarking this one, because I have exactly the same problem. I did all the steps, aaaannnnd nothing. No signs of life. At one point I was able to boot from an SD card, but that stopped working too. My theory is that somehow the bootloader has become corrupt, but so far fixing that has eluded me. I do not yet have a USB->TTL serial adaptor, but to have so simple a task go so horribly wrong is not encouraging.

To see so many people having the same problem as you and I is not encouraging either. Radxa really needs to reengineer this somehow. In the meantime, some sure-fire automated approach to fixing the bootloader from Radxa would really help.

In the meantime, I did find this, which might help. It describes how to use U-Boot via a serial connection to fix the more recalcitrant boot problems:

https://wiki.radxa.com/Zero/install/Boot_Troubleshooting#:~:text=all%203%20partitions.-,From%20inside%20U-Boot,bootloader%20according%20to%20the%20instruction%20listed%20in%20the%20previous%20section.,-Modify%20bootloader%20on

Sorry for the delay. We just returned to work after a 5-day national holiday.

This line indicates you are still running Android bootloader, which is not compatible with Linux. Try sudo boot-g12.py radxa-zero-erase-emmc.bin again, and after the program is finished, wait for additional 10 seconds for the code to run in your board. You should be able to lsblk and find a new USB storage device. You can then flash Linux images to it.

Tried the 20220616 ubuntu focal img - got Android

i just tried using that, and this is now my output

Well you need to run the command from where you keep radxa-zero-erase-emmc.bin file.

Hey, I still haven’t gotten a reply about this

#10

This line indicates there are issues with your eMMC. You might knocked some parts on your board. Can you take picture on both sides of you board?

#12

Notice anything physically wrong with my board?

#13

Sorry for the delay. It looks fine at a glimpse. I’ll get some testing U-Boot binary out this week with some possible workarounds to see if that can fix the issue.

#14

Actually I found a board that I can reliably reproduce the eMMC issue (boot into the system, dd eMMC to /dev/null, reboot). A few observations:

  1. The issue seems to be related to board temperature. dd made components hot and then the board fails to reboot. Once the board cooled off it can boot normally again.
  2. Linux did not report any error before reboot even when components are hot.
  3. In U-Boot, I can run mmc rescan then part list mmc 2 would work and loading some small file would also work. However, initramfs still cannot be loaded.

The few workarounds I tried did not work so I won’t post them. I’ll check the U-Boot driver to see what was causing the issue.

#15

Printed a lot of debug logs and an workaround was found. Please flash the following u-boot.bin.sd.bin.zip (596.4 KB) to your eMMC and see if that helpes. In serial console press Ctrl+C to interrupt u-boot autoboot, then run ums 1 2 to expose eMMC as a USB disk to your host computer. Then run following commands on your host Linux computer (replace sdX with real device):

            sudo dd if="./u-boot.bin.sd.bin" of=/dev/sdX bs=1 count=444
            sudo dd if="./u-boot.bin.sd.bin" of=/dev/sdX bs=512 skip=1 seek=1

If you cannot get this to work I’ll be back on Monday.

Instructions/tips for anyone struggling to get started with the radxa zero (USB boot mode and erasing/writing to eMMC)
Can Boot From One uSD But Not Another
#16

Just tried your 22.04 u-boot from post above and dd’d that onto an armbian image on emmc.

Armbian then succesfully booted from emmc

=> version
U-Boot 2022.04-00001-g5e1abbe4f8-dirty (Jun 17 2022 - 21:55:52 +0800) radxa-zero

aarch64-linux-gnu-gcc (GCC) 12.1.0
GNU ld (GNU Binutils) 2.38

mmc@ffe07000: 2
=> mmc dev 2
switch to partitions #0, OK

Hello, I am trying to setup my new Radxa zero for booting linux.

But I am already stuck with this, I tried USB3 and 2.0 ports, the best shortest cable I have, no luck but a time out. Please help:
