What is XTAG3 UART used for?

Post by daniel3550 »

In XTAG3 hardware manual I see pins 17 and 19 of xSYS Connector are for UART between target and host. What is this used for? I can't find any other documentation on it.

I think that's just a carry over from old stuff. Now you'd want to use a link and print through xscope if possible. I believe xtag3 still supports it though so if you had no links avail but can sacrifice 1 or 2 pins for uart you can use them. Better than jtag, worse than xscope for performance.
