Hello folks,
I've seen a similar topic(link) on this forum, but it had no solution, I'll take my chance and see if you could offer me some tips on how to debug this.
I've designed a custom "break-out" board for STM32WB5MMG and I'm trying to communicate with the MCU via SWD using a STLINK-V3 MINIE but unfortunately, it's not able to detect the target MCU even though I have connected the MCUs PA13/SWDIO & PA14/SWCLK directly to STLINKV3.
I've referred to the data sheet on page 16 to the best of my ability on how to design the breakout board but still I am not able to communicate with the MCU. (see schematic below)
Am I missing something here?
Any tips would be greatly appreciated thanks!
