I have installed Yocto image in the Raspberry Pi 4B previously and I know that the current architecture is armv7l by using uname -m. However, I want to change the architecture to ARM64/AARCH64.
Anyone knows how to configure it?
By the way, ARM64 and AARCH64 are the same thing, right?

As mentioned here, it is exactly the same thing. It's just a different notation based on the used compiler (LLVM => arm64 or GNU => aarch64) .

I have solved this issue by changing the machine type to "raspberrypi4-64", and it works fine now.
