mkresin:

Would you please give the attached patch a try.

If it still does not work, please try again with a stock configuration. Means, no extra packages like zram etc.

If you report bugs for custom builds, please paste always the output of ./scripts/diffconfig.sh.

Btw. your zram seem to have issues as well:

[ 20.226080] zram: Unknown symbol lz4_compress (err 0) [ 20.231361] zram: Unknown symbol lz4_decompress_unknownoutputsize (err 0)

Seams to me that either a dependency to [[http://lxr.free-electrons.com/source/lib/lz4/Makefile?v=4.4|CONFIG_LZ4*]] is missing or zram is compiled with lz4 support where it should not. Maybe you can investigate the issue by yourself and provide a patch.

bittorf:

is does work! the zram-problem message is there since ages, but zram is working. here the output of the new image, which a produced like this:

make menuconfig (my changes)
make target/linux/clean

apply your patch

make

scp + sysupgrade image

mkresin:

The issue is not fixed by my patch.

It took some time till I figured out what's the reason for the jffs2 errors. You have done a sysupgrade from a version prior r1597 and preserved the config.

To preserve the config a small jffs2 partition is created and a tar.gz archive with your config files is written to this partition. On next boot, the config is restored from this jffs2 partition. With [[https://git.lede-project.org/925e63e71fa6691f3fa374f71c77d0a91c7e7539|r1597]] I've enabled support for 4KB sectors and the flash chip of the MiWiFi Mini supports 4KB sectors.

During sysupgrade with preserving the config from a version prior r1597, a backup partition with 64KB sector size is create. On boot of the new image, the kernel (with 4KB sector size support) recognizes the mismatch of the sector size of the flash chip (0x1000 bytes) and the sector size used for creating the jffs2 backup partition (0x10000 bytes) and at warns about it. Not sure if the restore of the config really worked for you.

It was finally fixed by running sysupgrade again.

I've no idea how this error could be prevented. The only solution I've so far for upgrading from a pre r1597 is:

  • create a backup (sysupgrade -b) and copy this backup to safe location
  • upgrade the running systems without preserving the config (sysupgrade -n)
  • restore your backup afterwards (sysupgrade -r)

Till now I wasn't aware of the jffs2 backup partition and never expected such an issue in regard to enabling 4K support in the kernel.

I have a miwif nano too.
But I can use 8M flash only

how do you use 16M flash ?
