Flash Driver

[Navin Boppuri]

Can I have the dd commands once again? I am not using busybox stuff.

Thank you.

That's one option. If your write() calls are the same or  a  multiple
of  the erase block size, the driver performs auto-erase. You you can
just read / write it.

Attached below is a small patch against busybox to add flash_info and
flash_erase as busybox applets. [That's  part  of  SELF,  our  Simple

the documentation so I could put it all up for FTP...]
