AM62A7: ATF/OPTEE compilation

Sushmitha K

Part Number: AM62A7

Hi ,

I'm Working with SDK_9.1

I tired compiling Uboot and kernel with "k3-r5-devkit" and "linux-devkit"

Please provide the command to compile the ATF and optee sources.

Hi @Hong Guan64,

We are using k3r5-devkit and linux-devkit cross compilers and ATF compiled properly.

But while compiling OPTEE source below error prints is seen

Command Used: make CROSS_COMPILE64=/opt/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux- CROSS_COMPILE=/opt/k3r5-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-oe-eabi/arm-oe-eabi- PLATFORM=k3-am62x CFG_ARM64_core=y

Error prints:

The log looks pointing to build toolchain compatibility issue.
I used the toolchain under "<SDK INSTALL DIR>/external-toolchain-dir" in AM62x SDK 9.0, and can build optee successfully.
Here is OPTEE toolchain reference
