santosh:

Having a 32 Gbit (4BG) flash device hits a limitation of the program since it uses 32-bit numbers,

for example, for the size of the erase operation,  the size to be erased (2**32) becomes 0.

Can you do the operation using two separate erase operations of size 80000000?

regards,

Michael T

Thanks for the reply Michael,

I even tried with 16Gbit (2GB) flash device, Got Nand size also 2048MB, But even the erase operation is not happening,

This is what I got output......... can you suggest?
