I belive that I forget to mention that the chip that we are currently
using is the 512 Mbit chip from STMicroelectronics.
I also have tested the to write directly to the nand with the
I've filled the first 4 blocks (65535 bytes) with data, and I can read
it back successfully and verify that it is identical to what I wrote.
What is the next thing I should look into?
Any idea of what I should test/look into would be very appreciated.
