waveshare rp2040 zero: LED do not blink

[bobwxc]

Hi,

With the newest uf2 file, its LED didn't show anything.

GP 16 <-> DIN WS2812 RGB LED

waveshare-rp2040-zero pin

And testing on demo.yubikey.com is also no reaction.

Maybe related with https://github.com/polhenarejos/pico-hsm/issues/3

Waveshare boards have a delayed ROSC initialization.

Try to compile as https://github.com/polhenarejos/pico-hsm/issues/4

export PICO_SDK_PATH=~/Devel/pico/pico-sdk
export USB_VID=0x234b
export USB_PID=0x0000
export PICO_BOARD=waveshare_rp2040_zero 
cmake .. -DENABLE_DELAYED_BOOT=1 -DPICO_BOARD=$PICO_BOARD -DUSB_VID=${USB_VID} -DUSB_PID=${USB_PID}
make -j4

Mainly compiles the firmware with a delayed boot option.

patched pico-sdk as https://github.com/polhenarejos/pico-hsm/issues/3

and compiled with

make

still no blink and no reaction.

This board is really confusing.

I am using a tiny2040 and I cannot reproduce it. What I can recommend you:

• Ensure that your pico is completely blank. Do a pico_nuke to ensure it.
• git pull your pico-fido repo AND git pull of pico-hsm-sdk in it.
• Compile with delay option enabled.
• Since you are using the latest version, it should respond to opensc-tool -an with a message like this:

  Using reader with a card: Yubico YubiKey OTP+FIDO+CCID
