I’m using Cytron Maker Pi Pico (non-wifi)
I’ve Uploaded debugprobe_on_pico.u2f
I’ve replaced the driver using Zadig
[env:pico]
platform = https://github.com/maxgerhardt/platform-raspberrypi.git
board = pico
framework = arduino
board_build.core = earlephilhower
board_build.filesystem_size = 0m
debug_tool = cmsis-dap
upload_protocol = cmsis-dap
debug_speed = 30000
build_type = debug
I’ve followed the wiring from the documentation
Pico A GND -> Pico B GND
Pico A GP2 -> Pico B SWCLK
Pico A GP3 -> Pico B SWDIO
Pico A GP4/UART1 TX -> Pico B GP1/UARTO RX
Pico A GP5/UART1 RX -> Pico B GP0/UARTO TX
When I try to upload I get this
Configuring upload protocol...
AVAILABLE: blackmagic, cmsis-dap, jlink, pico-debug, picoprobe, picotool, raspberrypi-swd
CURRENT: upload_protocol = cmsis-dap
