ARM64 platform is hardware dependent, so only the images and hardware listed bellow are tested and guaranteed to work fine.

Someone else has reported the same issue before, currently I have no idea about it.

[JamesLewisLiu]

I think try rebuilding part of file on the cloud machine may solve it but I have no idea about how to rebuild the ventoy on arm machines

[amazingfate]

I have exactly the same code on a rk3588 SBC, which has an opensource edk2 UEFI firmware. It seems that BOOTAA64.EFI has some api that my UEFI firmware doesn't support.
@ventoy do you know how to locate the exception code from the above log like PC 0x000637DBF228? grub-mkimage doesn't generate BOOTAA64.EFI with debug symbols. And I can build ventoy myself to get debug symbols from file like ventoy.module.
If I can find where the exception happens I can look into the edk2 source code to see how to support ventoy from UEFI firmware.

[amazingfate]

@JamesLewisLiu Does your machine support UEFI secure boot?

[ventoy]

@JamesLewisLiu
You can try the latest 1.0.94 release.
