Hi,

again I have a problem with DAVE 4.1.4 and the new XMC devices.

I have a XMC1404 device and the UART 4.1.2 app. No other app at the moment.
I configured to use USIC module 0.

I'm not able to set the RX pin to pin 0.14 and the TX pin to 0.15 by using DAVE.
These pins must be used for ASC bootloader (28.1.1 in the user manual) but they are not offered
in the Pin Mapping view or in the Manual Pin Allocator view.

Any idea what I'm doing wrong or how to fix this issue?

Any help is appreciated.

Hi Michael,

Pins 0.14 and 0.15 are reserved for the debug interface SWD0.
If you do not require debug interface or if you are using SWD1 (P1.2 and P1.3), you can go to the CPU_CTRL_XMC1_0 app to configure/disable the debug interface under tab.

1755.attach

The changes will be updated and the pins should now be available for selection.
