I can't initialize twice the dataflash on an AT91SAM9263-EK board with SAM-BA v2.7
Question
On the SAM9263-EK board, If I execute several times the Enable Dataflash (SPI0 CS0) script, I've got the following error:

-E- Script error: Error Initializing DataFlash Applet (Can't detect known device)

Then SAM-BA hangs.
Answer
The SAM-BA Dataflash applet must be updated to handle multiple dataflash initializations.

Copy the isp-dataflash-at91sam9263.bin file in the following folder: C:\Program Files\ATMEL Corporation\AT91-ISP v1.11\SAM-BA v2.7\lib\AT91SAM9263-EK
