Hi all, This is my progress so far:
=== Week 1 === * Read U-Boot SPL code for AM335x to figure how it could be used to load custom binaries. * Set up the BeagleBone Black, experiment with U-Boot command line. * Started reading the available ARM Packages in edk2 to see what all can be reused.
=== Week 2 === * Saw portions of the StarterWare code to see how it does things. * Wrote a bare metal application to print a character stream over UART as per the TRM [1], facing some problems with initialization.
=== Next === * Debug the bare-metal binary, otherwise load it from U-Boot instead of MLO * Study the HisiPkg code and start implementing features for AM335x according to UEFI specs.
===Week 3 === * Got the standalone binary working through U-Boot [1] * git init [2] * Looking at ArmVExpressPkg and HisiPkg ports for reference.
=== Current Goal === * Build a dummy edk2 image to print over UART and load it from the SPL.

Varad,
I am not sure clock & timer libraries are really needed beyond the PEX stage. If you want to demo independence of u-boot SPL you could use the starterware boot loader instead. It should be pretty similar to what you have already working.

Hey Bill,
I am now going with getting the UEFI console running instead of implementing the low level libraries. For now, I plan to continue using SPL to load the UEFI image.
This is my progress update so far:
=== Week 5 === * Configured JTAG debugger with OpenOCD * Started working to bring up UEFI console

How far do you think you're likely to get by the end of the GSOC?
Cheers,

I'll have MMC support in a day or two, followed by the documentation. Are there any stretch targets I could add?

Hi Varad,
* Created a wiki[1] containing file descriptions and build process
(please review)
In general, your wiki looks good, it's have all needed information (from my POV). Here is some quick notes from my side (it's up to you -- to take them into account or skip).
1. If you wanted to show the *whole* boot process of BBB, there is also ROM-code at AM335x which can be considered as *very 1st bootloader*. Details here: http://processors.wiki.ti.com/index.php/AM335x_U-Boot_User%27s_Guide#Two_sta...
2. Regarding your command for building BBB package: you may want to try and source edksetup.sh file (". ./edksetup.sh"), after that you should be able to run "build" tool w/o specifying relative path to it. So if that's the case, you can insert sourcing command before building and get rid of relative path. It's also good idea because I saw you are using cygwin (AFAIR it's some windows tool), and most developers here using Linux, so they have another toolchain than you, so they can have another path to "build" tool.
3. Is there any way to boot edk2 w/o u-boot (directly from ROM-code)? If so, which further work should be done for this in BBB port? This stuff should be documented as well (IMO).
4. Boot process can be shown more detailed, like this: http://oi58.tinypic.com/2czeyb4.jpg
5. If you have some notes, ideas and TODOs for those who would like to continue working on your port -- it would be nice to share it in your wiki (in the end, I guess)
6. Add $ sign before this command: sudo screen /dev/ttyUSB[device] 115200
7. ...and also consider using "minicom" instead of "screen" as serial console tool (AFAIK most guys in TI and Linaro using minicom).
8. For wiki structure -- check out next links:
1. http://omappedia.org/wiki/6AJ.1.3_Release_Notes 2. http://omapedia.org/wiki/Panda5AJ.1.5.1_Release_Notes
if you like the way they organized -- you can rewok your wiki a bit
9. Table Of Content: is there any way to add it to GitHub wiki? If so, maybe it's good thing to do.

...and also consider using "minicom" instead of "screen" as serial

I used to, but it has some horrendous bugs (hence advised against in u-boot documentation), and after ckermit got broken in Debian packaging once, I use screen exclusively. Many others do the same.

=== Next ===
- Fix PcdGet() (maybe a toolchain problem)
- Get DEBUG() working
- Load DxeCore.

=== Week 8 ===
- Load PrePeiCore from U-Boot's SPL. Sec not needed.
- Documented the work so far [1]
=== Next ===
- Pass through PEI, construct HOBs and jump to DXE
This is fun!
