problem with mtd on a Sandpoint

[Claire Troussier]

Hi,

I use Montavista 2.4.2_hhl20 with a Sanpoint (8240) board and I try to
acces the flash. I add the mtd support in the kernel configuration and
during boot the flash is correctly identified. When I try to access it I

always got the same error "can't locate module block-major-31" or "can't

locate module char-major-90" if I use mtd0 instead of mtdblock0

Any ideas ?

Thanks for your help

Claire

Here are the boot messages regarding the flash detection
