UBI assert failed in ubi_wl_init

[Timo Ketola]

Hi again,

One further detail:

I tried to increase the UBI volume size from 48M to 64M. It didn't
affect the borderline, where the issue starts to manifest.

I already mixed up some terms and numbers so I try to wrap up everything
here:

           | UBI volume size MiB:
  mtd size |   48 |   64 | 1800
-----------+------+------+------
0x04000000 |      |  na  |  na
0x4E680000 |      |      |  na
0x4E6A0000 |   X  |   X  |  na
0x7C000000 |   X  |   X  |   X

X: The issue is there
na: obviously not possible

UBI volume size is what I put into ubinize.cfg vol_size variable.

By 'the issue' I mean specifically the assertion failure:

> UBI assert failed in ubi_wl_init at 1666 (pid 1)
