AM625: OP-TEE Build fail SDK9.2

Hello,

JHi said:

I guess I can use the pre-compiled version found in prebuit-images/am62xx-evm ?

Yes, you can use the pre-built images from the above directory.

Could you share the output of the following command:

echo $CROSS_COMPILE_64
echo $CROSS_COMPILE_32

echo $CROSS_COMPILE_64
/home/xxxx/ti-processor-sdk-linux-am62xx-evm-09.02.01.10/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-

echo $CROSS_COMPILE_32
/home/xxxx/ti-processor-sdk-linux-am62xx-evm-09.02.01.10/k3r5-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-oe-eabi/arm-oe-eabi-

Thanks for sharing. I will build at my end and verify.

Hi,

You need to use the correct compilers as mentioned in the link here: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_02_01_09/exports/docs/linux/Overview/GCC_ToolChain.html#external-arm-toolchain

On using them, it will not give the build error.

From the page you linked: It is strongly recommended to use the toolchain in the Processor SDK which is the version tested for TI platforms. And as you can see from my answer, I was using the compilers from the SDK. But you mean that the compilers inside the SDK are not suitable to compile OP-TEE?

Hello,

You have to use the following toolchains:

CROSS_COMPILE_64-> aarch64-none-linux-gnu-

CROSS_COMPILE_32-> arm-none-linux-gnueabihf-

SDK Toolchain Setup

Below variables need to be setup to be able to compile with the toolchains packaged in the SDK. These will be referenced by the build commands of the Foundational Components in this document.

host# CROSS_COMPILE_64="${SDK_INSTALL_DIR}/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-"
host# SYSROOT_64="${SDK_INSTALL_DIR}/linux-devkit/sysroots/aarch64-oe-linux"
host# CC_64="${CROSS_COMPILE_64}gcc --sysroot=${SYSROOT_64}"
host# CROSS_COMPILE_32="${SDK_INSTALL_DIR}/k3r5-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-oe-eabi/arm-oe-eabi-"

Maybe you should then update the documentation. I could compile everything else with the toolchains, but not OP-TEE.

Were you able to resolve the issue ?

Well, I'm not going to install different toolchains just to compile OP-TEE. But I would like to know, if you ever tested the toolchains you deliver with the SDK? And well I expect you to change the documentation that you will need different toolchain than delivered with the SDK to compile OP-TEE.
