When I plug my XRP into a USB port, it appears as a USB drive in File Explorer.
I tried https://xrpcode.wpi.edu/ from chrome, but it is unable to find the XRP, and the website does not appear to provide any further instructions. (Perhaps the website requires a serial connection first, before it can provide instructions?)
I also tried downloading the latest USB file from Releases · Open-STEM/XRP_MicroPython · GitHub and pasting it into the USB drive corresponding to the XRP. After a power cycle, the XRP still appears as a USB drive, and the uf2 file is no longer there.
My XRP board is not defective. Here’s what I had to do to get it working:
Download flash_nuke.uf2 and upload it to the XRP board. Note: my board was stuck in bootloader mode, where it appears as a USB drive. If the board is not in this mode: Hold the Boot button and tap the Reset button once, then release the Boot button.
