Adding MDoC+32/64M support to diskonchip new driver
Hi,
I'm trying to add 32/64M support to diskonchip new driver, I made few changes and I manage to read partition information.
However I'm still having some problems, for example
when I read page offset 0x18000 I get data by reading first 528 bytes but after that I get 0xff and ECC fails.
below is my log file

Could that be because my device still using M-System Trueffs and flashed with wince!!! I have MDoC+ 64M.
I'm also sending patch I made against latest version in CVS with the changes I made so far.
