I have made a custom RP2040 PCB. When I connected the PCB using USB to PC, it is attaching as mass storage device. But when I am copying a uf2 file for blink and it got unmounted. But nothing is happening.
If I am copying uf2 file for micropython, then the PCB is getting re-mounted automatically after some times and the uf2 file is getting removed. It's like the PCB is vomiting the micropython uf2 file.
Using winbond W25X20CL flash.
