Hi Tiger,
sorry if I was not clear enough in my previous email. But using ARM Trusted
Firmware instead of Bootstrap is the right approach to follow. As I said in my

Hi, Oliver:
Based on arm trusted firmware's doc : user-guide.md .
I followed these steps to get a dedicated version uefi
e to load UEFI.fd ?
Best wishes,

Hi Tiger,
Yes we do not need to patch the BaseTools. I have updated the instructions.
Where did you get the sources from? From Linaro? We do not have the
directory 'ArmPkg/Drivers/AcpiTables'

Thanks Bhupesh to have replied to the email. Here are some clarifications.
We should not mix ARMv8 / AArch64 / AArch32 / ARMv7.
ARMv7 and ARMv8 are the revisions of the ARM Architecture.
- ARMv7 (version 7) is 32bit only.
- ARMv8 (version 8

Hi Tiger,
Yes, the Trusted firmware runs in EL3 and calls the UEFI boot firmware which
runs in EL2.
In the trusted firmware project
https://github.com/ARM-software/arm-trusted-firmware
you will find the instructions
2-bit AArch32 code.

Hi Tiger,
You can use the AArch64 foundation model support code in the EDK2 code base to
write reference code for your ARMv8 SoC.
Also which toolchain do you use for compiling your AArch32 (32-bit code)?

Bhupesh

Hi Tiger,
AFAIK, the AArch64 ISA is written from scratch for 64-bit support.
Although it is backward compatible with AArch32 and binaries compiled
for AArch32 (ARMv7 comp

Hi, Oliver:
I have a question abourt ARMv8 CPU's bootloader.
ARMv8 supports: AARCH32 / AARCH64
Take an example:
An ARMv8 SOC, when power up / reset, its default state is : AARCH32
Then, could i still run an old arm uefi bootloader which written by
ARMv7 instruction set?
I will switch ARMv8 SOC to A
