Hi Loic,
just a quick comment about this last ASSERT(), I will come back on the other
points later. I think I understand what is going wrong here. It is a bit tricky
...
Before building the UEFI firmware, you have to prepare your UEFI build
environment. To do that:
1) You set up the environment variables with: . edksetup.sh `pwd`/BaseTools
2) You build the Tianocore BaseTools
Unfortunately, the Tianocore BaseTools are broken as you know ... And we have
to apply a patch (or a set of patches ...).
I have just remembered you said you had troubles with the toolchain at the
beginning. I guess it is because you did not apply the patch.
What happen is this patch changes some compilation flags in the toolchains.
These compilation flags are in [EDK2_ROOT]/BaseTools/Conf/tools_def.template.
When you typed '. edksetup.sh `pwd`/BaseTools' the script copies
[EDK2_ROOT]/BaseTools/Conf/ to [EDK2_ROOT]/Conf/.
But if you change any files in [EDK2_ROOT]/BaseTools/Conf/ and you call again
'. edksetup.sh `pwd`/BaseTools' the configuration files will not be overwritten.
It is I think why you have got this ASSERT(). One of my patches changes the
compilation flags in [EDK2_ROOT]/BaseTools/Conf/tools_def.template to fix the
generated relocation symbols. But in your case, you was still using the old
configuration file.
A workaround if you applied the patch after trying to build the BaseTools a
first time is:
1) rm -Rf Conf/*
2) make -C BaseTools clean
3) . edksetup.sh `pwd`/BaseTools
4) make -C BaseTools
Let me know if it is better.
Olivier

Subject: Re: UEFI on BeagleBoard qEmu
To try the resulting image, I just did:
qemu-system-arm -mtdblock \
../Build/BeagleBoard/DEBUG_ARMGCC/FV/BeagleBoard_EFI_flashboot.fd \
-nographic -M beagle
which sent this on the serial port:
UART Enabled
Magic delay to disable watchdog timers properly.
ASSERT_EFI_ERROR (Status = Unsupported)
ASSERT
/home/lool/git/edk2/edk2/edk2/EmbeddedPkg/Library/PrePiLib/PrePiLib.c(73):
!EFI_ERROR (Status)
I didn't actually look into this issue yet.
