Hello,
My plan is to validate that I can address both a Freescale Kinetis KXX (Cortex-M4) and a Kinetis KLXX (Cortex-M0+) on a same board using a single debug connector.
As Kinetis L serie has only Serial Wire interface (so JTAG chaining seems not to be an option), I imagine connecting both MCUs in parallel on SWDIO and SWDCLK and use the multi-drop extensions defined as part of Serial Wire protocol version 2 in ADI (ARM Debug Interface) v5.1.
I briefly tried to connect two TWRK40 boards in such parallel configuration but I manage to connect to only one of the two targets.
My questions are the following :
- Does J-Link already allow to address multiple targets through a single Serial Wire connection ?
- If not, is there a plan to do so ?
- What is your feeling about such plan ?
Kind regards,
