I downloaded the 3.8.0 source code for op-tee through repo and used it in the build folder:

Cd build

Make - f toolchains. mk toolchains

To obtain the cross compilation tool, but I encountered an error using make - f qemu.mk all image This is my server information and information about the cross compilation tool image I realize this is an architectural issue, but I am unable to https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads Find a suitable cross compilation tool to re download to the toolchains folder. I am a college student who is interested in op-tee and I hope to receive help. Thank you Basic: I cannot switch the architecture to Intel's servers

If you use something more recent, preferably the latest release you'll have toolchains available for AArch64 hosts.

my optee versioin now is 3.8.0，So I should download the latest version of OPTEE to solve this problem, right? I followed the instructions in a book step by step, so I didn't know what to do after the failure here. Thank you for your reply. I currently understand that if I modify my cross toolchain to use arm64, I may need to replace the makefile content, such as qemu.mk

Should I use QEMU to simulate Intel architecture to run code

Yes, it would be the easiest option. You can find instructions at https://optee.readthedocs.io/en/latest/building/devices/qemu.html#id3 (64-bit OP-TEE for Armv8) and https://optee.readthedocs.io/en/latest/building/devices/qemu.html#build-instructions (32-bit-bit OP-TEE for Armv7).

No.

Thank you very much for your reply, it is very helpful for a beginner, wish you a happy life, I will try to use qemu_v8.xml next to get the code to run again
