many bad blocks

http://linux-sunxi.org/Mainline_NAND_Howto#Many_bad_blocks

To fix many bad blocks issue you should:

1. Disable nand-on-flash-bbt in your dts
2. Remove this test: http://lxr.free-electrons.com/source/drivers/mtd/nand/nand_base.c?v=4.7#L2940
3. Boot your new kernel and erase chip with flash_erase /dev/mtd[0-X]
4. Re-introduce the bad block check removed in 2, re-enable nand-on-flash-bbt
   and boot the new kernel

Let's try to do this with armbian.

cubieboard

First, enable nand overlay

dpavlin@cubieboard:~$ cat /boot/armbianEnv.txt
overlays=nand

Then remove nand-om-flash-btt:

dpavlin@cubieboard:/$ cd /boot/dtb-`uname -r`/overlay
dpavlin@cubieboard:/boot/dtb-4.14.23-sunxi/overlay$ 

# backup original
root@cubieboard:/boot/dtb-4.14.23-sunxi/overlay# cp sun4i-a10-nand.dtbo sun4i-a10-nand.dtbo.orig

# remote nand-on-flash-bbt
root@cubieboard:/boot/dtb-4.14.23-sunxi/overlay# dtc -I dtb -O dts sun4i-a10-nand.dtbo | grep -v nand-on-flash-bbt > /tmp/nand.dts
root@cubieboard:/boot/dtb-4.14.23-sunxi/overlay# dtc -I dts -O dtb /tmp/nand.dts > sun4i-a10-nand.dtbo

Compile armbian kernel with this patch applied

dpavlin@armbian:~/build$ cp ./patch/kernel/sunxi-dev/nand-disable-badblock-check-for-migration.patch.disabled \
    ./userpatches/kernel/sunxi-next/nand-disable-badblock-check-for-migration.patch

Reboot and check that nand is available:

dpavlin@cubieboard:~$ dmesg | grep -A 8 MTD

This doesn't actually work for me (since it's missing device tree overlays), but rebasing to current u-boot master doesn't
produce code which compiles.

after a bit of fiddling with cables (it's always cables, right?)

Lovro contributed that if you are getting continous output like this

Change ST-Link/V2 mode 0002 -> 0001

ValueError('Status of core is not halt.', 128)

then run this while holding reset active (hold tweezers on both side of C3)
that should hand the uC in a mode that will enable stlinkv2.py script to turn off the flash rom protection and erase the flash while doing that

It seems that every peace of hardware I have needs a separate page. When I first bought it, I didn't have any problems with it.

Since then, some kernels have problems with USB suspend, but following works:

apt-get install cups splix

And then select ML-2150 in cups.
