Hi
I am using STM32L4 Nucleo board to develop an aplication which will be using the SWPMI port.
I've been reading around and seems that the debug framework is already using it? So my question would be, how do I use the SWPMI_IO port for communication and still being able to debug.
As seen in the figure the bit SWP_TBYP bit switches the SWP kernel interface.
I guess that if I want to use the SWPMI_IO signal, I would need to debug using an external JTAG interface.
regards

Which L4-NUCLEO, and why would it clash with SWD debug? PB12 on the L4 isn't involved in that.
Up vote any posts that you find helpful, it shows what's working..

I tried it on STM32L432 Nucleo 32 and will try also on the STM23L433RCT.
The picture was taken from an ST SWP presentation for L4 cpu's..so I guess PB12 should be taken as PA8 in the L432.
