Hello.
pre-filling with 0xff creates a proper boot loader image, but no
bad-block marker is there when written to flash.
Isn't there some kobs-ng or whatever tool it was to properly initialize
the NAND on MXS ?
I didn't know. I used what u-boot offers, which works for me without
vendor tools -- and dare I say I trust u-boot tools more than vendor
tools?.
The default environment even has the rule to reflash from any
u-boot.nand you manage to put into RAM. The only issue is that
u-boot.nand, as created, marks good blocks as bad by prefilling with
zeores.
But what about the bad block markers , do they get erased when you write
this U-Boot image into the NAND ?
I think the vendor tool somehow dealt with it (but it might have
depended on some weird stuff in GPMI NAND), I don't think I ever used
that tool myself.
