I had some problems with 12.2, so I use version 11.3.1 (as of 28/2/23)
ARM_TOOLCHAIN_VERSION=11.3.Rel1
curl -Lo gcc-arm-none-eabi.tar.xz "https://developer.arm.com/-/media/Files/downloads/gnu/${ARM_TOOLCHAIN_VERSION}/binrel/arm-gnu-toolchain-${ARM_TOOLCHAIN_VERSION}-x86_64-arm-none-eabi.tar.xz"
sudo mkdir /opt/gcc-arm-none-eabi
sudo tar xf gcc-arm-none-eabi.tar.xz --strip-components=1 -C /opt/gcc-arm-none-eabi
Add export PATH=$PATH:/opt/gcc-arm-none-eabi/bin to .bashrc or .zshrc
Open <SDK_ROOT>/components/toolchain/gcc/Makefile.posix and set the correct path
