I need to find out which pin on my board the chip's uart rx line is connected to. My chip is a s3c2410 (arm920t). I can connect through jtag and execute openocd commands. Is there any way to get some output on a certain pin of the chip through jtag? Something boundry-scan like that I can then probe all the pads I have available to find out which one is the uart rx. How do i go about toggling output on a certain pin (it's pin is k17 - RXD0/GPH3) through openocd?
