Hello,
I'm trying to debug
https://bugs.openwrt.org/index.php?do=details&task_id=2742.
So far, what I discovered:
1) it happens only in master, 19.07 is fine on both ath79 and ar71xx
2) it happens only in ath79. ar71xx is fine in master
3) rootfs_data (mtd4) contents keeps changing on each read. Each time I
run: "dd if=/dev/mtd4 | md5sum - " I get a different hash.
4) I get the random data reading flash from firmware (mtd1), rootfs (mtd3)
or rootfs_data(mtd4), but always around the region where rootfs_data is
(after squashfs). I could not identify the exactly upper and lower
boundaries where it happens (addresses are random).
5) I also happens without mounting jffs2 (failsafe)
6) Most mtd4 is 0xff (as expected). Only sparse bytes or sequence of bytes
contains other values.
7) I looked for a string inside mtd4 (if I came some a buffer), but changes
where too small and without any sequence of printable chars.
There are plenty of longs in the bug report.
Has someone faced something similar?
Regards,
