Hi,
Seen this commit in your branch https://git.openwrt.org/?p=openwrt/staging/
nbd.git;a=commit;h=b18993dcaf5ae57d4569a9606dd707e5380e9382 and have couple of
questions:
- Will this work on ramips mt7621?
- Could this potentially solve a problem in current master with kernel 5.4
when flashing openwrt builds randomly soft bricks endgerouterx due to bad
blocks(not sure but this particular device has 1 bad block in kernel2 and one
in the ubi partion) ?
I have the same symptoms as described here https://github.com/freifunk-gluon/
gluon/issues/1937
