hello,

Would someone can teach me how to create a binary file for NAND flash programming?

according to Samsung booklet, for Gang programming there are several procedures
1. generation of O/S image
2. Add meta data in spare array based on physical format of FTL
3. write master image to nan

for step 1&2, they are done on PC level.

for step 1, I have u-boot, uImage, and filesystem.yaff2 ready. but I don't know how to combine those three files into a single O/S image. is there any tool available?

for step 2, also would someone advise how to do it or give me some reference?

Thank you very much.

typically, you'd make a series of separate partitions in the NAND, and put the components into different partitions (for instance, u-boot would go in partiton 0, it's environment vars would go in partition 1, the kernel would be in partition 2, and the fs would be in partition 3).

If your board doesn't even have a basic board diagnostics service booting, you'll need to get a jtag, or other hardware interfacing component, and manually load everything before you can boot the board on its own.

What board is this? It's difficult to say exact procedures without knowing the exact board.

Hello,

Thanks for your explainations.
Here we don't plan to use JTAG as it is slow for factory image burning. We are now sourcing ROM writer, e.g., Data I/O, which is able to write 256M NAND flash.

I have no idea what's relatiohship between output image and board specfic information.
We are using Samsung S3c2440 as processor and NAND04GW3B2 from STMicroelectronics.
Any suggestion is welctome.
