Hardware Legit Picofly?

[Daak]

I bought a picofly for switch oled off aliexpress but I cant write firmware to it. No storage device is detected. When I plug the board into USB, it shows solid blue lights and then blinking green/yellow lights. Its it fake? FW already written? Or maybe somehow I dont know the procedure for resetting the FW? Thanks

Did you press the button on the picofly while inserting the usb cable in the pc/laptop?

Yup tried both buttons while plugging in and after being plugged in. it does the same thing every time.

If it's a USB-C cable, try flipping your cable. It's possible that they didn't properly wire their pins. You may only be getting power delivered through your cable, and no connection on data pins, thus your PC would power the board, but not put it in programming mode.

The picofly modules I had so far, had all fw preinstalled.
And if the picofly is blinking blue and than yellow, a working fw is on it so far.

I have some which go straight in device mode and open a folder if connected to my pc and
I have some where I need to hold BOOT button while connecting to the pc for entering the device mode

since you have yellow blinking error code, you should have 2.7 or up fw on the chip and you could do upgrade via pico_toolbox_0.2.bin and sending update.bin

Just a heads up, there is no "legit" picofly. Picofly is the firmware for the RP2040.
