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.

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
best wishes Tina
