Raw Flash Writes

["Raghav K" <raghavk@myw.ltindia.com>]

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,
