NOR flash - validation failed

Working with the AT91SAM9260 controller from atmel, I get a lot of errors when I try to program the NOR flash AT49BV160 which is connected at NSC0.

The problem is, that I have no communication at NRD, NRW0 and NCS0, when I try to program the flash or turn on the power of this board (BMS pin is high during the reset).

During the programming via the jtag interface I get a lot of errors (validation failed). Erase and programming was successfull (said uvision).

Maybe someone of you working with this controller, could show me the right commands / settings (especially to configurate this flash).

thank you in advance - best regards

Hi Stefan,

I would then suggest to you:

- try another chip, perhaps that one is damaged
- try to arrange with Atmel to send them your board so
  they try to get controller working
- ask Atmel if they have any development board using
  SAM926x chip with NOR Flash, so you could try on
  original Atmel development board and look at the
  signals
- choose another non-volatile memory like SPI
  Dataflash or something similar with SDRAM

Best regards, Milorad
