Hi, We’re seeing a positive pulse in pin 6.5 while powering up, resetting & programming (via SWD). Please see the attached screenshots. The pin is port 6, which also has SWD and reset lines. We tested the pin with various configurations via ...Read more
Hi, out of my one experience in switch mode power supplies there are a couple of key points to follow when doing these designs. 1. Insure all resistors are 1 type, this limits the change over temperature which in turn will limit the output change variations. 2. Insure the track from the switching poRead more
Hi,
out of my one experience in switch mode power supplies there are a couple of key points to follow when doing these designs.
1. Insure all resistors are 1 type, this limits the change over temperature which in turn will limit the output change variations.
2. Insure the track from the switching point is close as possible to the coil and doesn’t add resistance to the coil.
3. Output capacitors require to hold a low ESR type
hope some of this helps.
Thanks & Regards

Hello,
By default, all GPIO pins start out at reset as Analog_HiZ. This means the pin though configured at initialization as a draw-down thing inactive low launches life floating until the boot initialization is complete.
still, also I suggest an average worth resistor( 100K?) drag-down to GND If this is your project case.
Thank You
