OpenOCD with AT91SAM7X256 and additional FPGA in JTAG chain

Hello,
I want connect the AT91SAM7X256 and an additional FPGA into one
JTAG chain for testing the board with boundary scan.

My question is, can I use OpenOCD furthermore under this condition?
Is it correct, that I have to configure the JTAG chain with
the OpenOCD command "jtag_device" for each device?

Thanks,
Frank

Hi,

Yes, you have to specify each device in the chain, starting with the one closest to TDO, but then OpenOCD should work with the ARM just like it does with a single device in the chain.
