Yes, this works… sort of. I was playing with edk2 and got a little too much hubris and tried to install it to emmc and now cannot boot from emmc,nvme or sd card with fresh image.
I was able to get into maskrom mode and connect to computer with SYSUSB port and it shows up under lsusb. Just make sure to jump pin 1 to 5 and 2 to 6 on the USB select jumper. I used some breadboard jumpers.
I am trying to reflash the base pocket-reform-rk3588 image using the linux upgrade-tool from the firefly site but am not having any luck.
Not sure what else to try at the moment, but it should be recoverable.
Edit: Found a github with some instructions for an older version of the rk upgrade_tools and I think using the raw write is the command to use. sudo ./upgrade_tool wl 0 pocket-reform-system-rk3588.img
I am still having an issue, but maybe because of the usb C to A adapter on my framework.
