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. IFWI blobs for the APL-I are provided by Intel and are
specific for different flavors of the MID silicon.*
*Normal IFWI eMMC boot process*

   1. *On-chip boot rom inits eMMC and loads IFWI from the MMC boot
   partitions*
   2. *IFWI looks for OSIP header at top of eMMC (MBR boot block)*
   3. *The header directs IFWI to the start, size, load address, and entry
   of U-Boot in eMMC*
   4. *(need clarification) If u-boot is not found, try the alt u-boot
   image at 5MB into the eMMC*
   5. *U-Boot is loaded into RAM and executed*

*OSIP stands for OS Image Profile, and it is nothing more and less than
INTEL name for very known old fashion MBR, considering DATA structure.*

Thank you in advance,
Zoran

So far Apollo Lake is not supported in U-Boot. However it is on my todo list.

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

I will need investigate this before commenting anything since this is
not a normal boot sequence supported in U-Boot.

Normally U-Boot boots from SPI NOR, and Linux can be loaded directly
from U-Boot via the 'zboot' command.

I am much more interested (since the last stage I know) what would be the
initial sequence of events:
E3900/APL-I -> IFWI -> MBR -> U-Boot, or ...???

Thank you,
Zoran
