Mixed success has been obtained using EDK2 on a pair of Pi3 systems, one running 13-stable and one running -current. The 13-stable machine is at stable/13-ef2aa7753 The -current machine is at main-n258665-e03b7883e97c The 13-stable machine boots reliably with an EDK2 microSD card and will boot almost as reliably with no microSD card at all. This seems true with both JMS561 and JMS578 usb-serial bridges. The -current machine uses an ASMT bridge and is unresponsive with either the EDK2 microSD or no microSD at all. It does boot reliably using the "special bootcode.bin" file from the Pi foundation. It appears to be the newer of the two Pi3's, having a non-latching microSD receptacle. On balance EDK2 appears to be useful, or at least having some promise. Bugzilla traffic suggests work is stalled, can it be unstuck? Thanks for reading, bob prohaska
