AM625: How To generate a Processor SDK LINUX AM62x from yocto using meta-toolchain-arago-tisdk

Alexis LOGNON
Intellectual 610 points
Part Number: AM625


Hello,

I need to generate the SDK linux for AM62x including the toolchain and all source needed to compile the linux kernel.

I use the SDK 09.02.01.02 and build the recipe meta-toolchain-arago-tisdk after I have build the recipe tisdk-default-image.

I installed it using the script deploy-ti/sdk/arago-2023.10-aarch64-linux-tisdk.sh.

When I have source the file /opt/arago-2023.10/environment-setup the toolchain is not found.

No file with prefix aarch64-none-linux-gnu- is avalaible in the /opt/arago-2023.10 directory.

How could I generate the setup file like ti-processor-sdk-linux-am62xx-evm-09.02.01.09-Linux-x86-Install.bin.

Regards,

Alexis.

    Hi Alexis,

    I just kicked off a build to investigate, it'll take a bit go through. A toolchain should be part of a "toolchain" installer target one would assume.

    Hi Alexis,

    I just built the meta-toolchain-arago-tisdk target from scratch for AM62x SDK v9.2, and then installed the resulting toolchain installer located at deploy-ti/sdk/arago-2023.10-aarch64-linux-tisdk.sh.

    Then, after sourcing the provided environment as per SDK documentation, I was able to find the 64-bit binary toolchains using the `which` command as follows:

    a0797059@dasso:~/tmp/arago-2023.10
$ source environment-setup
[linux-devkit]:~/tmp/arago-2023.10> echo $CC
aarch64-oe-linux-gcc --sysroot=/home/a0797059/tmp/arago-2023.10/sysroots/aarch64-oe-linux
[linux-devkit]:~/tmp/arago-2023.10> which $CC
/home/a0797059/tmp/arago-2023.10/sysroots/x86_64-arago-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-gcc
[linux-devkit]:~/tmp/arago-2023.10> $CC --version

    You can see the relative path of the compiler binary is sysroots/x86_64-arago-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-gcc. The compiler binary executable itself is named slightly different than from what you were looking for (reflecting it's an OE-built toolchain) but the point is this is the correct toolchain for working with SDK v9.2.

    Hi Andreas,

    I find the toolchain prefix in a TI web site, ti should be wrong.

    But if I follow the SDK 09.02.01.02 documentation :

    https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_02_01_09/exports/docs/linux/Foundational_Components_Kernel_Users_Guide.html?highlight=device%20tree#compiling-the-device-tree-binaries

    I can't build the kernel source because CROSS_COMPILE_64 is not defined by the setup-environment script.

    I done :

    $ CROSS_COMPILE_64="$CC"

    $ make ARCH=arm64 CROSS_COMPILE="$CROSS_COMPILE_64" distclean

    $ make ARCH=arm64 CROSS_COMPILE="$CROSS_COMPILE_64" defconfig ti_arm64_prune.config

    But I got the error : 

    HOSTCC  scripts/basic/fixdep
    In file included from /storage/opt/arago-2023.10/sysroots/aarch64-oe-linux/usr/include/features-time64.h:21:0,

     #include <bits/timesize-32.h>

    Could you give me the right method to build the SDK 09.02.01.02 kernel and device using the SDK generated.

    Regards,

    Alexis.

    Hi,

    I also set the variables as below, but with the same error.

    export CROSS_COMPILE_64="${SDK_PATH_NATIVE}/usr/bin/aarch64-oe-linux/${TARGET_PREFIX}"
    export SYSROOT_64="${SDK_PATH_NATIVE}"
    export CC_64="${CROSS_COMPILE_64}gcc --sysroot=${SYSROOT_64}"

    If you want to build the Kernel you should NOTsource the environment script, instead just use the toolchain binaries directly. You can setup CROSS_COMPILE_64 like shown on the top of the page here: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_02_01_09/exports/docs/linux/Overview/GCC_ToolChain.html#yocto-toolchain  (there's a note on that documentation page too regarding building the kernel).

     #include <bits/timesize-32.h>

    This is likely coming from having (re-)defined $CC when sourcing the cross toolchain environment. Again, don't do that for Kernel builds. It needs to access the host toolchain as-is. If things get redefined, this no longer works.

    Hi Andreas,

    I build the kernel and the device tree without any errors.

    Thanks.

    Alexis.

    Hi Alexis,

    glad to hear, also I do appreciate you closing the loop here.
