Hi,
I developed a board using RP2354A and wrote a program using Visual Studio Code with the Raspberry Pi Pico Extensions, using Board "Pico2".
The good:
a) I can program the RP2354A via SWD
b) The program (I2C output to display) runs as expected
c) The serial monitor via USB-C works fine
d) The core voltage is 1.10V
The bad:
e) The Reset does not work. I measured the voltage at the RUN pin using PCBite probes, measuring the correct voltages 3.28V (no reset) and 0V (when RESET button pressed).
My program is not stopped by the reset (0V at RUN pin), it always runs. Also the example Blink program runs fine, but is not stopped by RUN=0V.
f) I connected the QSPI_SS pin via 10kOhm to 3.3V and via 1kOhm and BOOT button to GND. When I press the BOOT button, I expect a voltage around 0.3V, but I measure 3.14V when the BOOT button is pressed and 3.28V when the BOOT button is not pressed. The button works fine, I measured 0V when pressed.
Because of e) and f), I can not load the program via USB.
Any idea? (Yes, I looked carefully at the schematic and PCB, I do not see any error)
How can I setup Visual Studio Code and tell that I am using the RP2354 (instead of "Board Pico2")? Sorry, I am new to VSC, I did not find a solution by myself.
