Hi everyone,

                     I'm using DEVKIT8000, i'm trying to write and read the data from the NAND in the U-boot only, i have called a nand_write_buf function in void start_armboot i'm  writing data through the buffer to the NAND but it is not taking, i have followed every steps first i have unlocked the NAND, then selected software ECC, while i'm trying to erase some block to write the data it is not working, can anyone  suggest me what is the problem in erasing the block. If you want t see my code i can provide you.

Thanks & Regards,

Guru Charan
