FS#3937 - MR32 BCM53xx boot error #8934
Comments
chunkeey: [ 4.730000] find_itb_subimage: error finding kernel@1: FDT_ERR_NOTFOUND There's a comment on a merged series "scripts: mkits.sh: replace @ with - in nodes " that could explain these errors: 5ec60cb#commitcomment-53657902
" the commenter also proposed a patch: An option to verify that it's indeed what causes the device to refuse to boot would be to revert the patch+"build: use config-1 instead of config@1 as default" (or try the proposed patch, which seems to do both). Also, do you need help "unbricking" the device? Or can you get into a shell? |
tbilan: I was able to unbrick. I booted into busybox and did a cp from part.old to part.safe and a reboot brought me back to the prompt and I reflashed initramfs from there. The proposed changes worked so I suggest merging them in. Another thing to note is that sysupgrade doesn't see it as a valid image so I had to --force to get it to work. The MR32 performs poorly though (about 7Mbps). The ac chip (BCM43520) doesn't have a kernel driver so it's limited to the bg chip. This makes the device undesirable at this time. It does technically work though and it's better than nothing. |
chunkeey: A new (supposedly) fixed snapshot image is available from: https://downloads.openwrt.org/snapshots/targets/bcm53xx/generic/ (sha256sum 0912b917026e913110573f9ba27b47ca102c214a93dffd74cfbf914ee26df02b) |
chunkeey: ... Any reports? I would like to make a patch for 21.02 but I would like to know if the snapshot image is now working as intended? Cheers |
There isn't any response from the user. The patch might fixed the issue. |
tbilan:
I have an MR32 I'm trying to flash. Following the instructions on https://openwrt.org/toh/meraki/mr32 I uploaded the initramfs successfully to part.safe. When rebooting the console has the following errors then boots back into the Meraki firmware:

I built the initramfs from the current git master (7/18/2021). I also had someone on #openwrt-dev build it and I tried theirs and received the same errors.
