Dear ARM-Community,

 

I have big problems to access the external dataflash (AT45DB081) via SAM-BA 2.12 and 2.16 on the eval kit AT91SAM7SE512. The Flash is connected with SPI on NPCS0.

The SAM-BA-Tool communicates over RS232 (I have unlimited access to the processor)

 

SAM-BA 2.12: - dataflash can be initialized but writing leads to an error or a frozen programm

SAM-BA 2.16: - the dataflash can't be initialized. The prog always stops with an error. There is no way to access the dataflash.

 

I have tried several PC's and several Evaluation Boards - it is always the same.

 

Please give me some advice, I am very clueless with this.
