I am working on my custom board, based on the reference design as described in https://datasheets.raspberrypi.com/rp20 ... rp2040.pdf (I am using the same components on my custom board)
On my first test board I am having some issues with the initial boot.
My firmware does not want to boot after its powering up. (3.3V power is applied). After the RUN pin is connected to GND, it boots up correctly.
All the GPIO functions and USB seem to work correctly, just initial boot does not work.
What could be wrong?
