Bad sector and Samsung S3C2440

Hello everybody,

I have a MIO P550, which is a PDA/GPS based on a Samsung S3C2440 @ 400Mhz.

I have developed a wm6.1 rom which works perfectly.

Yesterday, when I have re-flashing my PDA, during the low level format ( from the boot loader) I have seeing “Get FMD block Status error = “ from 1% to 56% !!

Fortunately, I could re-flash my PDA, and it boot without problem,but my NAND have many BAD BLOCK !

I would like to find a solution in order to correct this error, and having no bad sector.

I’m software programmer, so I have knowledge in programming but no on the S3C2440 ! Anyone could give me information about the solution for repairing my BAD SECTOR?

I can enter on boot loader, so flash on SD card, or, I can access to my PDA in USB with the DNW.EXE program ( I have my drivers !)

Great thanks for all , and sorry for my bad English, I’m French.

regards,

Nixeus
