Hello,
I've got a board with the AT91RM9200, where a u-boot bootloader is installed. Now, I want to erase the external flash (SPI-Flash) where the bootloader is installed to write my programm to the target without a bootloader. But I always get the message "no jtag target found". The COM LED from the ULINK is blue. So I don't know why I have no access to the device.

right - I will call them tomorrow. But if you are right, and the right pin row is GND, the left pin row is not suitable with the ulink2, is it?
best wishes Tina
now I get the right connections for the jtag interface - it's almost the same connection of the ARM 20-Pin Connection (Ulink2).
So I use the 16-pin connector with the 20-pin ARM connector and connect the first 16pins - but it doesn't work....
The only difference is, that the 16-pin connector on the board has no RTCK (AT91RM9200) and therefore the company has left this pin unconnected...
I don't know where could be the problem now... the JTAG speed is 100kHz, and I connect the jtag connector to the board and then I turn of the voltage, so that the u-boot bootloader don't start.
I hope anybody could help me with this problem
