On rango dmesg:
[ 8.106096] ubi1: attached mtd9 (name "syscfg", size 86 MiB)
[ 8.228609] UBIFS (ubi1:0): UBIFS: mounted UBI device 1, volume 0, name "syscfg"
mamba dmesg:
[ 7.838078] ubi1: attached mtd8 (name "syscfg", size 38 MiB)
does not appear to try to mount, no message as to failure. But this seems wrong:
root@OpenWrt:/tmp/syscfg# cat /proc/mtd
dev: size erasesize name

mtd10: 00008000 00008000 "spi0.0"
only recall there being 10 partitions.
Edit: guess not, old post, wiki is wrong as well.
