What have I done to the bootloader?
ok, so I made the mistake of trying to put a seeed 2mic hat on my roc-rk3328-cc and it trashed the bootloader for some reason. I dorked around with it for hours and I know nothing about compiling a system but I kept reading and trying. In the end I've ended up with a weird solution. It seems that if I load an image (one of their ubuntus or armbian) it will try to boot but get all kinds of errors but if I load the same image on a usb stick and pop it in as it tries to boot, it switches to the usb and runs perfectly from there. Not really complaining as it runs great off of a usb3 stick, but I've got to keep the SD card installed or it won't boot. Can someone tell me what I have done?!?
