Hello, Dear Everyone!

Could you explain the way to copy U-Boot, loaded with MFG Tools / Mxsldr into the RAM, to NAND flash?

Thank you very much!

As I understood it can be made by "nand write ... ". But how can I find out addresses and size of u-boot to copy?

My bootloader size is 3m (0x300000). So what should I write?

nand erase 0x0 0x300000

nand write 0x0 ??? 0x300000
