FS#1710 - Mir3g - unable to install OpenWrt/LEDE with ubi bad blocks #6688
Comments
mkresin: Would you please provide a full bootlog. So far I can't spot anything wrong. Block 939 is bad, is marked as bad (ubi0: mark PEB 939 as bad) and will not be used any more. The UBI format should continue afterwards. Hard to say what really happens due to the truncated log. |
Ultraboss77: I thought this part was sufficient. |
mkresin:
It was. Failed to get that the boot stops with the mark PEB as bad message. //edit Had a quick look at the code and suspect that something in [[https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/ramips/patches-4.14/0039-mtd-add-mt7621-nand-support.patch;h=d50e689110eab3e8c140261600561b150b960089;hb=b9bd3285c7c6fbc60374b05ac2da9be41ce75651#l3049|mtk_nand_block_markbad]] causes the hang. More detailed debugging would require access to the hardware/need to be done by someone with the hardware. |
majuss: I have exactly the same problem, still not fixed with latest image :( |
pablos891: I have the same issue. The OpenWrt bricks my Mir3g. Starting from this post: https://forum.openwrt.org/t/xiaomi-wifi-router-3g/5377/1028?u=pablos891 |
ivanich: Having the same issue with edgerouterx |

We are some users unable to complete the installation of OpenWrt/LEDE because erasing bad blocks on ubi partition fail :

[ 4.597931] ubi0: mark PEB 939 as bad
A user (@tanonn, thanks to him) successful installed LEDE by shrinking the ubi partition (85% of the original size) then made a custom build.
Could you handle the erasing of bad blocks for next builds ?
