I'd like to thank both of you for the light you've shed on the boot problems encountered with RPi. For the moment I'll go back to my original goal of getting Pi2's to boot from the JMS-based usb-serial bridges presently on-hand. Preliminary experiments using a JMS561 bridge and a Pi2 using the version of bootcode.bin located at https://github.com/raspberrypi/firmware/raw/master/boot/bootcode.bin [referring page https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#special-bootcode-bin-only-boot-mode] seem to be promising under -current. The interest I expressed in EDK2 appears to have been misguided, or at least premature. I was hoping it might be a more tractable replacement for u-boot, but it's equally inscrutable to an amateur. Worse, only the macciatobin flavor builds under poudriere and my attempts at a plain "make" build using FLAVOR=rpi3 have so far failed on the same host. With my thanks, bob prohaska
