=== Week 11 === * DxeCore now loads * Fixed PcdGet() issue by correcting PcdFdBaseAddress according to SPL * DEBUG() works * InterruptDxe, TimerDxe, WatchdogTimerDxe and TimerLib added
=== Next === * Add BDS dependencies, launch BDS * Document * Depreceate Sec and PrePeiCore since using PrePi, cleanup build spec files.
Thanks, Varad

=== Week 9, 10 ===
- Since memory is already initialized by SPL, launch from PrePi.
- Place TexasInstrumentsPkg into edk2 [1].
- PCD issue from Week 7 - in BeagleBoardPkg as well - thread: [2]
=== 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!

=== Week 7 ===
- Issue with DEBUG(): internal assertions fail and macro returns.
(proper PCDs and Libraries used)
- Issue with SerialPortWrite(): strings with >4 characters fail to
print. (am waiting for TX FIFO to clear before sending in the next char)
- Added PEI phase to SEC itself (as done in BeagleBoardPkg).
- Better option: Have a separate PEI phase (follow D01 instead of
BeagleBoard). Using ArmPlatformPkg/PrePeiCore; figure out how to jump.
- Issue with PcdGet32(PcdFvBaseAddress): returns 0 for valid
PcdFvBaseAddress
=== Next ===
- Fix the issues listed (figure out why PCDs not showing up)
- Load PEI

=== Week 6 ===
- Built Shell.efi with BeagleBoneBlackPkg
- Could not launch from SEC; dependencies unmet. Need to follow SEC ->
DXE -> BDS -> Shell.efi
- Added DXE call to BeagleBoneBlackPkg
=== Next ===
- Get DXE debug output from the board.

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
=== Next ===
- Get console working.
Thanks, Varad

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.
