raspberry pi pico bootsel mode unable

[heyitsmeyo]

Hello github people , i wanna put some attention on a problem that i m sure a lot of people here already faced when trying to enable bootsel mode on the rpi pico using picotool :

No accessible RP2040 devices in BOOTSEL mode were found.

but:

Device at bus 3, address 12 appears to be a RP2040 device in BOOTSEL mode, but
picotool was unable to connect.

I fortunately tried to make pico sdk project that can solve this issue :

https://github.com/heyitsmeyo/rpi-pico-2040bootselmode

use this command :

sudo picotool load bootloader_reset.uf2 --bus --address

-f

I hope it works !

Just a tip , whenever you work on pico sdk projects , make sure you include the stdio_usb.h library in your c file

and on your CMakeLists.txt : pico_enable_stdio_usb( 1)
