Hello everyone

I am trying to invoke the EDK2 shell on Aarch64 SOC.

Here is my shell prompt

[1] Shell

[2] Boot Manager

Start: 1

add-symbol-file /home/yehuday/projects/uefi/edk2/Build/SOC/DEBUG_GCC48/AARCH64/ShellPkg/Application/Shell/Shell/DEBUG/Shell.dll 0x1A831000

Loading driver at 0x0001A830000 EntryPoint=0x0001A831000 Shell.efi

UEFI Interactive Shell v2.1

EDK II

UEFI v2.50 (Marvell EFI Nov 19 2015 09:40:40, 0x00000000)

Mapping table

      FS0: Alias(s):F3:

          VenHw(C5B9C74A-6D72-4719-99AB-C59F199091EB)

No SimpleTextInputEx was found. CTRL-based features are not usable.

No SimpleTextInputEx was found. CTRL-based features are not usable.

Press ESC in 5 seconds to skip startup.nsh or any other key to continue

From here on any key I press causes  call to “GccSemihostCall” which invokes a HW breakpoint on AArch64.

I noticed GccSemihostCall doesn’t trigger a breakpoint in ARM arch.

I am using “ SemihostLib|ArmPkg/Library/SemihostLib/SemihostLib.inf”

Do you have any idea why I get to “GccSemihostCall”.  ?

Am I missing something in my system setup. ?

I copied the shell related packages from ArmVirtPkg since I know it works there

Thanks
