hi, forgot to flash the pico before soldered it to the bluescsi v2 board. But now I can't get it to go into flashing mode by holding down the boot_sel. Is there any work around? or do I have to desolder the pico?

thanks in advance eddie

You do not need to remove the pico to flash. Make sure you're using a USB cable that isn't power only (they exist!).

Hold down boot sel, connect to a computer via USB, copy the .uf2 file to the drive that shows up.

If I hold boot_sel and plug the usb into the PC, nothing happens, it doesn't go into the usb drive mode.

Does this microUSB cable work for data transfer on other devices? It sounds like you have a power-only cable. I regularly reprogram soldered-down pico modules via USB, it should work fine.

I usef the same cable to flash another pico to make sure it worked. So the cable is fine. I guessed i will desolder it tomorrow

Did you figure it out? Maybe a solder ball or something got where it shouldn't.

Had to desolder it from the board. Then I can get the pico into flashing mode. I did try to power the board and flash, but still no good.
