rb433uha + r22269 "error occured while reading from "NAND 512MiB 3,3V 8-bit""

Reported by: sites@… Owned by: developers
Priority: normal Milestone: Backfire 10.03.1
Component: base system Version: Trunk
Keywords: Cc:


After a fresh install of OpenWRT r22269 on an rb433uha i'm not able to install any software with opkg. the output of df -h only includes the two temp volumes:

Filesystem                Size      Used Available Use% Mounted on
tmpfs                    62.0M      1.1M     60.9M   2% /tmp
tmpfs                   512.0K         0    512.0K   0% /dev

but mount looks normal

root@OpenWrt:/# mount
rootfs on / type rootfs (rw)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,relatime)
tmpfs on /dev type tmpfs (rw,relatime,size=512k)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
debugfs on /sys/kernel/debug type debugfs (rw,relatime)
none on /proc/bus/usb type usbfs (rw,relatime)

i'm able to write to / just to test that there is still space left.

The only hint i have are this lines from dmesg

# Bad eraseblock 1494 at 0x000017580000
# Creating 3 MTD partitions on "NAND 512MiB 3,3V 8-bit":
# 0x000000000000-0x000000040000 : "booter"
# 0x000000040000-0x000000400000 : "kernel"
# 0x000000400000-0x000020000000 : "rootfs"
# mtd: partition "rootfs" set to be root filesystem
# split_squashfs: error occured while reading from "NAND 512MiB 3,3V 8-bit"

you can find the full dmesg here

It's related to #6812 and #6846.

There was problem with wrong size of kernel partition for r4xx which has 512mb NAND (rb433uha and also part of rb433ah). It was fixed in trunk r23293. Try this revision and check if it solves problem for you.

It wasn't yet merged to backfire, so trying latest backfire would be useless
