Hello Bin, > So far Apollo Lake is not supported in U-Boot. However it is on my todo list.
All Good. Please, take your time. If you do not mind, I would like to know ASAP, do I have correct prediction/anticipation/vision how this whole thing should work? The one I originally described in my original/intro email to this email thread? Namely: E3900/APL-I -> IFWI -> MBR -> U-Boot -> eLinux/YOCTO ?! With the following/forwarding explanation (please, in original email)? It is very important for me to know how the future U-Boot architecture will look like for E3900/APL-I! I would like to thank you in advance, Zoran Stojsavljevic _______ On Thu, Oct 5, 2017 at 11:27 AM, Bin Meng <bmeng...@gmail.com> wrote: > Hi Zoran, > > On Wed, Oct 4, 2017 at 1:52 PM, Zoran Stojsavljevic > <zoran.stojsavlje...@gmail.com> wrote: > > Hello to the U-Boot Community, > > > > I am curious about the following HW/FW configuration with regards to the > > U-Boot? > > > > Did anybody managed to run the following: INTEL Atom E3900 APL-I with > > U-Boot? > > > > E3900 -> IFWI -> MBR -> U-Boot -> eLinux/YOCTO ?! > > > > Here are some explanations regarding the terms/context: > > > > *IFWI is the Intel FirmWare Interface, a binary blob loaded from the eMMC > > boot partition that executes a secondary loader (in this case U-Boot) > from > > the main eMMC.
