Hi ,
I am using STM32WL33 in my design and just received my first PCB assembled.
i am trying to flash the board with basic program but no success yet , it would be great if you can help to find the problem.
i have tried with both CubeIDE and Cubeprogramer with STlink V2 , seems like debugger is connected but not going to further steps .here is the screen shots
i have used same ST linkV2 and setup in another board (STM32WLE5) and i can connect.
schematic:
I checked the SWDIO, SWCLK, VDD, GND and NRST pin connection to ST link it looks okay
I checked the voltages VDD : 3.3V, VCAP:1.2V , NSRST:3.3V , VFBSD(SMPS output):1.4V
No pullup resistor in NRST and PA10 pin is floating.
Circuit is design based on ST reference design
Any help is appreciated
