So here is a weird thing I've noticed with a STM32U073...
CubeMX shows that this CPU has the "Trace Asynchronous SW" option, but for this mcu it is no longer listed under SYS, but under its own category: "Trace and Debug" -> "DEBUG". Anyway, after enabling it, the signal shows up on the graphical pinout, with the name "DEBUG_JTDO-SWO". This is pretty much the same as i was used to with other STM32 mcu's.
So when i was designing a PCB for this new STM32U073 MCU i assumed it had support for SWO (or SWV or whatever the name is). But now when I'm trying to debug this MCU, the debugger doesn't allow me to enable "Serial Wire Viewer (SWV)" in the debug configuration properties of STM32CubeIDE. The option is just greyed out. So I did some more digging in the datasheet for the STM32U0, and I'm starting to wonder if it even has support for SWO/SWV?
Can anyone enlighten me? Is this just a problem with the debug config in STM32CubeIDE, or does the STM32U0 have no SWO/SWV capabilities?
I'm running STM32CubeIDE 1.19.0
