Hi everybody,
I am working on a bf537 stamp board
Everytime i try to write on flash i get this error :
ERROR: ioctl(MEMGETINFO) failed, errno=25
I can erase the flash blocks ,but i cant mount them (when i try to mount /dev/mtdblock1 for example)
here is the kernel log :

that value given to -o doesnt make any sense. you give it an offset from the start of the mtd partition ... whether it is memory mapped, or SPI based, or whatever does not matter.
