From c945d6e6160598894319860a92b602a192c2c268 Mon Sep 17 00:00:00 2001 From: Antonio Borneo Date: Mon, 12 Oct 2020 00:12:05 +0200 Subject: tcl/target: start using the new TPIU/SWO support Create the TPIU and SWO device in target config file. Replace the target event 'trace-config' with the TPIU/SWO event 'post-enable'. Extend the existing code in the event handler to properly set the gpio mode and speed to permit synchronous trace. This patch is not exhaustive of all the targets that have SWO, but has to be considered as an initial example.
