[newbie] How to get the value of active pins through JTAG

Started by C...T January 6, 2004
My advisor assigned me a problem which is to monitor the value of active
pins of an ARM processor which will run a embedded OS.

The ARM processor is on an evaluation board - amtel eb63 and the OS is
dos-like. I have wiggler in hand. Boss's idea is using the boundary-scan to
get the value while the OS is running.

Please tell me if it is possible to do this and what I should do or learn to
finish this task.
