NAND Partitions on ARM

NAND Partitions on ARM

[Fabrizio Grasso]

Hi all,
I'm using S3C2410A from Samsung and SMDK2410 from Aiji System. Kernel is 
2.4.18 from MIZI and bootloader is VIVI version 0.1.4 .
I'm trying to partition my NAND flash (64MB) by using VIVI commands. The 
result I obtained is:

Under /dev/bon I can see all 4 partitions... but under /dev/mtdblock I can 
see only "0" !!
What I'm missing?

My system boots from NAND and mounts FS in ram. I'm trying to make 
partitions to have one of them readable/writable at runtime... I'd like to 
have the last partitions to store personal data!

Has anybody any suggestion?

Thanks a lot

Really, you should be using a 2.6 kernel, but since no-one seems to
care enough about the support, there has been little work done on
the smdk2410 boards.

pre 2.4.26 is far too old, and all the work is being applied to
the 2.6 series. At least someone has loaned me an smdk2440 to
allow better support for that board.
