Looking for NUCLEO-WBA52CG schematic so I can enable SWO debugging

RCool.1 · ‎2023-04-30

Using the NUCLEO-WBA52CG I have been trying to get debug logs to be set over SWO(PB3). Using a logic analyzer I can see the logging getting to CN4:10(PB3/SWO). The signal does not make it to the embedded STLINK-V3MODS pin 6. There are notes in the development board reference manual (UM3103) that say modifications to solder bridges are necessary. These modifications are not documented in the manual and I have been unable the proper arraingment with continuity testing.

A copy of the carrier boards schematic would be a big help.
