Per atf_and_trusty_README.txt in atf_src.tbz2 source code, if I want to build atf then need download armhf toolchain, but I don’t know how to download armhf toolchain and which version should be used?
May you help it?
Thanks a lot
hello wuhailin,
you should download here, [url]http://releases.linaro.org/components/toolchain/binaries/7.3-2018.05/arm-linux-gnueabihf/gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf.tar.xz[/url]
please defining CROSS_COMPILE_ARM_PATH to armhf (32-bit) toolchain to build trusty sources.
thanks

FYI, armhf is 32-bit and has not been used since the TK1. The provided toolchain is arm64/aarch64.
I confused that I get the source code of ATF from L4T R32.6.1(for Jetson AGX Xavier board),
It says we should use armbhf toolchain (used by CROSS_COMPILE_ARM_PATH ) in atf_and_trusty_README.txt, it is correct or not?
that’s correct, you’ll need both 64-bit and 32-bit toolchain to cross-compile the trusty sources.
There’s something I forgot about: Bootloader code itself is probably still all 32-bit. On the other hand, if you are compiling a recent kernel, then you shouldn’t need an armhf tool. So I missed that you are probably not compiling just a kernel.
