Before it failed in the expected way. After, it succeeded, but built edk2 for macchiatobin that wasn't useful. I couldn't figure out how to make poudriere attempt to build the needed rpi3 flavor and didn't find a flavor for rpi2. This was on a Pi4 running -current. It's unclear to me if edk2 offers any advantage over u-boot, at least when u-boot works. I think HPS's changes to usb probably did help, but won't know for a while yet given the erratic nature of the troubles. Thanks for all your help! bob prohaska
