Hello everyone!
Currently I'm using a custom arduino pcb based on the rp2040. It records data on a flash chip and later transfers it to an sd-card. I would like to get rid of the large sd card footprint on my next board, so my question is, is there a way to access files from the flash chip via usb on a pc? I would rather not have to send it via serial, but to be able to just copy and edit the file directly in the file explorer. Thank you for helping!
I know little of the RPi series of devices so this may be of little use to you!
It sounds like you need some code for the RPi to make it appear as a Mass Storage Device to the PC. I don't know enough of the detail to know whether the flash chip has to have a FAT style file system on it or whether the software will need to carry out the necessary translation.
A quick google search of "RP2040 mass storage device" reveals many hits on the topic.
There's a Sparkfun page that talks about the UF2 bootloader and the opening paragraph says:
With the UF2 bootloader, the RP2040 Thing Plus shows up on your computer as a USB storage device without having to install drivers for Windows 10, Mac, and Linux!
