Resolved! Cannot Flash STM32WB55CEU6
Hello, I have a custom board with a STM32WB55CEU6 and I am trying to programm it through a Nucleo STLink with SWD. The onboard Nucleo CPU is detected and works fine if I add the jumpers, and I can program a different STM32 board with the jumpers remo...
Resolved! STM32WBA5MMG GND pads near antenna
Dear all, I have a custom PCB with the STM32WBA5MMG module. I missed the keepout requirement in the reference design and pads 2 - 5 and pads 56 / 59. These pads are connected to GND in my design. I did some signal tests, and I have a feeling the ante...
