Hi.
Because we have a board with 2 XMC's and only 2 lines to the outside (SWDIO + SWDCLK), we need a possibility to program both XMC's individually.
Is it possible to programm (and also debug) two XMC1400 over the same SWD, if we switch them (SWDIO + SWDCLK) in parallel?
On the XMC1400, there is not JTAG, where we have the possibility for a daisy chain.
If it is possible, how can i access one of the XMC's over Segger JLink and how can I distinguish them?
Thanks.

Hi,
Cortex M0 does not support Multi-drop SWD.
You can try multiplexing SWDIO and SWDCLK. See https://devzone.nordicsemi.com/f/nordic-q-a/35094/what-is-the-swd-driver-impedance-of-swdio-line

Jesus
