Thanks again, guys!
I was wondering if one of you guys might be willing to own/submit a wiki page article around this board, howto get rolling with CentOS etc ?
I was planning to do just that this weekend when I get mine up and running. :-)
I am very much in favour of the way Jeremiah has his set up, though. Having u-boot as the stage 1 bootloade before TianoCore UEFI adds a lot more flexibility at the relatively trivial expense of adding a seconds or two to the boot time.
5 seconds only to be precise, at least on my board :)
Is that because the interactive boot keypress timeout on u-boot defaults to 5 seconds? I ask because that is actually adjustable. :-)
:) no, that was just coincidence. I was actually referring to 5 secs being the difference between tftp and mmc loading. I haven't burned UEFI permanently.
Oh, I see. I was always intending to have UEFI on MMC. I only ever use TFTP when setting up diskless machines with NFS root or for unbricking.
I'll be using mmc in this case too, despite it being a tad slower, as my stupid netgear switches don't not like LAG(Port Trunking) outside of an OS.
