Raw Flash Writes

Greetings all,

My system has the flash interleaved to give me an effective sector size of 256kB;

A write to an entire erased sector of flash causes my kernel to crash, however the writes to the same in smaller chunks with a small delay seems to work fine.

Is there some sort of limit in "write-chuck" size or any timeout placed on a write operation considering that it is "synced". If so how can this be modified ?

I've also tried to "cat 256k_file > /dev/mtd4", this too drives my kernel crazy.

Any and all help appreciated.

Thanks and Regards,
