Dear all,
I want to use the SEGGER SAM-ICE JTAG Emulator together with an Atmel AT91SAM9261 based board.
The JLink Drivers are correctly installed and the emulator is recognised correctly by Windows XP.
However when I start the JLink Commander I get the following messages:
Display All
VTarget is correctly displayed but JLink doesn't seem to find a supported CPU.
A subsequent reset of the cpu shows the following:
Display All
The JTAGSEL signal of the processor is in low state which means the processor is running in ICE mode. I think this should be OK right?
Any comments or ideas on this would be highly appreciated.
Thanks and with best regards,
Markus Franke
