AM625: Missing files in SDK build from meta-toolchain-arago-tisdk

Hi Alexis,

Alexis LOGNON said:

I have 2 file: environment-setup and environment-setup-aarch64-linux, but none of the files allow me to build my applications.

You need to use environment-setup when working with the meta-toolchain-arago-tisdk -based toolchain installer. You can remember you got the correct one because the command prompt will turn into [linux-devkit].

Alexis LOGNON said:

I use the same source code for the apps that is successfully compiling using bitbake.

It seems some system header files are missing :

For environment-setup-aarch64-linux the error concerns <sys/mman.h>.

For environment-setup-aarch64-linux the error concerns <errno.h>

Are you saying when you search through the installed toolchain directories those header files are nowhere to be found? When I check the toolchain installer from the SDK v8.6 those files are in there.. see below. You should see something similar from the installer you created based on SDK v8.4 sources. Those are very basic header files.

I tried to follow the thread : https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1202155/faq-am6x-am335x-am437x-using-a-yocto-internal-toolchain-for-target-image-builds-and-cross-development-sdk-installer-generation-with-yocto-dunfell-based-v8-x-sdks-for-sitara-mpus
But my SDK is sdk 8.4 not 8.5 as requested in the thread.

This steps should work more or less for all TI Processor SDK Linux v8.x variants. Perhaps a patch may not be needed or doesn't apply cleanly, but those things should be easy to figure out if they occur. If you have a specific issue adopting this solution let me know and I can provide some additional guidance.

Alexis LOGNON said:

So could you tell me what is the best way to fix the issue:
1 - Force the patch on SDK 8.4
2 - Upgrade to 8.5
3 - Upgrade to 8.6
4 - Switch to kirkstone if it is a stable release ?

I wouldn't expect moving to 8.5 or 8.6 having any impact on your particular concern, as the "Yocto table stakes" should be more or less the same. What will be the main benefit of going to 8.5 or 8.6 will be the better and more robust support of AM62x device features mostly through updated Linux Kernel and U-Boot trees that are included. You can see the changes here:

Hi Andreas,

Here is the search of the file in the SDK installation folder:

# cd /usr/local/arago-2021.09

# find . -name mman.h

# find . -name errno.h

./sysroots/x86_64-arago-linux/usr/share/ti/cgt-pru/include/errno.h
./sysroots/x86_64-arago-linux/usr/share/ti/cgt-pru/lib/src/errno.h
./sysroots/x86_64-arago-linux/usr/share/ti/cgt-c6x/include/libcxx/errno.h
./sysroots/x86_64-arago-linux/usr/share/ti/cgt-c6x/include/errno.h
./sysroots/x86_64-arago-linux/usr/share/ti/gcc-arm-none-eabi/arm-none-eabi/include/sys/errno.h
./sysroots/x86_64-arago-linux/usr/share/ti/gcc-arm-none-eabi/arm-none-eabi/include/errno.h

So there's nothing in sysroot directory.

After executed : source /usr/local/arago-2021.09/environment-setup

The prompt is unchanged, my shell is :

$ echo $SHELL 

/usr/bin/zsh

Yesterday I launch to compilation of the SDK from fresh setup (docker Ubuntu 18.04.6 LTS) :

1 - SDK 08.06 :

./oe-layertool-setup.sh -f configs/processor-sdk/processor-sdk-08.06.00-config.txt 

MACHINE=am62xx-evm bitbake tisdk-base-image && MACHINE=am62xx-evm bitbake tisdk-base-image -c populate_sdk

2 - SDK 08.05 :

./oe-layertool-setup.sh -f configs/processor-sdk/processor-sdk-08.05.00.21-config.txt

git -C meta-arago am 0001-meta-toolchain-arago-fix-internal-toolchain-installe.patch

git -C meta-ti am 0001-optee-os-Fix-SRC_URI-to-allow-inherited-patch-to-get.patch

There's no error when patch are applied.

MACHINE=am62xx-evm bitbake tisdk-base-image && MACHINE=am62xx-evm bitbake tisdk-base-image -c populate_sdk

For both I have the same error :

Could you give me the history of the commands you executed step by step to make the SDK build from a fresh setup, please ?

Could you also confirm the configuration to add to local.conf to add extra package sush as Xenomai.

I spent to much time to debug the SDK, it is the fourth time I rebuild the SDK from scratch.

So we need to figure out what the issue is coming from ?

I really need to deliver a fully working SDK version 08.04.01.04, could you provide additional guidance. please.

Thanks for your help,

Best Regards,

Alexis.

Hi Andreas,

Could you answer as soon as possible to this thread, it blocks the deployment of the development tools (SDK) to our dev Team.

Regards,

Alexis.

/usr/bin/zsh

Can you configure using 'bash' as the system shells. It's one of the requirements for the build. Not sure how you ended up with 'zsh', usually Ubuntu default is 'dash' which doesn't work with our SDKs, causing very strange build issues. See here:

https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/08_04_01_09/exports/docs/linux/Overview_Building_the_SDK.html#prerequisites-one-time-setup

I'm setting up and kicking off a clean build using processor-sdk-08.04.01.09-config.txt (this is the latest version of the AM62x SDK v8.4.x you want) and will try generating the toolchain installer using the official bitbake meta-toolchain-arago-tisdk method first (with no added packages) and have a look at the header files and report back here in a bit.

Regards, Andreas

Hi Alexis,

I setup a clean environment, built the devkit installer, verified the header files you are looking for are there, the environment can be activated successfully, and everything is working including compiling a small program that accesses a definition from errno.h. Please find all the steps below.

Note the 'sed' patch step in there is needed due to me installing this on Ubuntu 22.04, it is not relevant to the issue at hand, but may also be helpful if you give the installer to somebody that doesn't develop on Ubuntu 18.04, so I wanted to include it here too.
