How to read image from NAND

Other Parts Discussed in Thread: AM1705

I am a novice , this my first project on AM1705.

I made the board on the Sitara AM1705 processor, wrote U-boot into NAND, then, by means of U-boot, wrote a Linux kernel and file system into NAND, then, from under Linux, wrote my application into NAND.

Now I need to read from NAND my image (u-boot + linux kernel + rootFS + my application) and to write it in other boards.

How it is possible to read an image from NAND? For this purpose I will need Code Composer Studio and JTAG?

Michael,

Its very tough to achieve this using u-boot as u-boot doesn't support file writes. You can use JTAG to read the NAND contents to a file in the host PC. But I guess this will take a lot of time. However this can be done for bootloaders. The best way to read it is to use kernel and use mtd tools to read it NFS or SD card. Later the whole image can be flashed to other devices using TFTP and nand write from u-boot.

Yes, thanks, I do exactly so (tftp and nand write from u-boot)
