The size of my dumped image is 150 MiB. Is it possible to partition the Nandsim to this custom size? Or is it possible to give an arbitrary size when loading the nandsim module? I have tried fdisk, parted, gparted without success.

Hi again,

I finally found how to set the size of the partitions of Nandsim: with the parameter parts. I.e.:

  modprobe nandsim first_id_byte=0x20 second_id_byte=0xaa third_id_byte=0x00 fourth_id_byte=0x15 parts=0x4b0

The first partition has the size = (0x4b0 * erasesize).

Hope this will help some people. In my case, this does not yet resolve my problem of dump image write/mount.

Bye.
