So your board is going to be an USB peripheral, right?
My question is how can i utilize mtd api to make the driver? Or anyone done that before? Or anyone can give me some advises?
Have a look at the fine Linux-USB Gadget project http://www.linux-usb.org/gadget
Your board should use the "File-backed Storage" driver, with the actual file
(mtdblock or mtdchar?) being accessed through the VFS.
Once you find out the details, some feedback on the list will be much
appreciated, especially from the next person asking this soon-to-be a FAQ :-)
Best Regards,
Dear Fillod
Actually, i do have a USB ram disk driver from the BSP of motorola, i also located the read write code to the driver, but it is RAM ,not flash.
I have a guess and please fix me.
Can I use the functions in <include/linux/mtd/CFI.h > to read/write/erase my chip (AM29PLD127 AMD CFI flash) DIRECTLY?
I think this can speed up my process if i need to rewrite the gadget driver on M9328 chip
Thanks for helping best regard Mike,Lee
