Comment (by anonymous):
Based on forum discussion there may be something wrong with the image
generation or with the image handling / end detection at the boot after
flashing. The initial "factory" image fails at the first boot to detect
the end of the squashfs firmware, and does not generate the proper jffs2
partition.
{{{
[ 54.260000] jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not
found at 0x003f0024: 0x6ac0 instead
[ 54.270000] jffs2: Further such events for this erase block will not be
printed
[ 54.330000] jffs2: Old JFFS2 bitmask found at 0x003f2d88
[ 54.340000] jffs2: You cannot use older JFFS2 filesystems with newer
kernels
[ 54.640000] jffs2: Cowardly refusing to erase blocks on filesystem with
no valid JFFS2 nodes
}}}
Manually running jffs2reset (=firstboot) then fixes things. Apparently it
is bypasses the partition end code market search and just overwrites
things. (based on partition sizes in mtd?)
This might be related to seama-header in DIR-645. It is one of the few
devices with that header. Possibly the uci-defaults script does not run
properly?
https://dev.openwrt.org/browser/trunk/target/linux/ramips/base-files/etc
/uci-defaults/09_fix-seama-header
The uci-defaults script runs in practice the command "mtd fixseama
kernel". One of you with the problem might try flashing again with the
factory image and try running that command after the boot. What errors do
pop up?
This might be related to r45896, which fixed endianness detection for trx
code in mtd. Might seama code in mtd have a similar endianness detection
problem? seama.c uses both BYTE_ORDER and BIG_ENDIAN, but does not include
<endian.h>. Adding that fixed things for trx.c.
