DRA821U: J7200_evm tiarmclang Linux tool chain issue

Jeffrey McLean

Part Number: DRA821U
Other Parts Discussed in Thread: DRA821

Hi,

I am trying to build for R5F using tiarmclang. This is my environment

Ubuntu-18-04-6-LTS
ti-processor-sdk-rtos-j7200-evm-09_00_01_01
CCS12.5.0
ti-cgt-armllvm_3.2.0.LTS
ti-cgt-arm_20.2.7.LTS

I have successfully installed all of the above. T.I.'s documentation says that tiarmclang is the preferred build method over gcc. The documentation says to run tiarmclang on the command line but I can't get that to work. Even if I run from within the ti-cgt-armllvm_3.2.0.LTS/bin folder the command is not recognized. I have read the TI Arm Clang Compiler Tools User's Guide .

The SDK notes https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j7200/09_00_01_01/exports/docs/psdk_rtos/docs/user_guide/sdk_components_j7200.html#ti-arm-r5f-code-generation-tools say ticgt is already included but I didn't find that.

v3.2

If you could please, can you answer all three of these questions :-)

Should I use gcc instead? What are T.I. folks are using internally to generate .xer5f files? I want to stay with what the support folks are using.
Is building on the command line the only way to make builds, is CCS ever used to make builds? There are no CCS examples in ti-processor-sdk-rtos-j7200-evm-09_00_01_01.
What is the connection between tiarmclang and ccs? In Windows it seems to be straight forward and it is part of the CCS tool chain, but I am confused here for Linux.

Thanks, Jeff

Hello Jeff,

Jeffrey McLean said:
ti-cgt-armllvm_3.2.0.LTS

ti-cgt-arm_20.2.7.LTS

How did you install these? What steps did you follow? The SDK install script will pull the correct compiler using ./sdk_builder/scripts/setup_psdk_rtos.sh. I don't see this script in the J7200 SDK, so I'm wondering where you pulled the compiler from.

This is the correct website download that we download the compiler for Linux from:

https://www.ti.com/tool/download/ARM-CGT-CLANG/2.1.3.LTS

Regards,

Erick

I will download the ARM-CGT-CLANG and see if I can get that to work. I did not see any reference to the script, ./sdk_builder/scripts/setup_psdk_rtos.sh. I checked and it is not in the PDK. Is there somewhere that I can get that script?

Yes, it is part of the J721E RTOS SDK, or even J721S2 or J784S4:

J721E SDK: https://www.ti.com/tool/download/PROCESSOR-SDK-RTOS-J721E

J721S2 SDK: https://www.ti.com/tool/download/PROCESSOR-SDK-RTOS-J721S2

I'm not sure why it was not included, I'll check with the development team why it is not part of J7200.

I've uploaded it here as well in case you don't want to download the whole RTOS SDK for the other devices:sdk_builder.tar.gz

Regards,

Erick

To answer, I downloaded the most recent,

ti-cgt-armllvm_3.2.0.LTS
ti-cgt-arm_20.2.7.LTS

They came as a .bin. I did a chmod a+x, and then ran them. So now I have folders with the same name. But they may be too far in front of the DRA821, they are v3x. I see you are suggesting to use the v2x.

But I think I still need the script from above.

Ah, I used your link to the release notes to check the version used in the SDK 9.0:

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j7200/09_00_01_01/exports/docs/psdk_rtos/docs/user_guide/sdk_components_j7200.html#ti-arm-r5f-code-generation-tools

Should be v2.1.3.LTS.

When I run the setup_psdk_rtos.sh script from the link you sent, sdk_builder.tar.gz it is looking for components that are not in the 721 SDK but are not in the 7200 SDK

But previously I had missed this folder that is in the SDK

ti-cgt-armllvm_2.1.3.LTS

sorry this is my first time through this. But I don't know how to use that. The instructions in the PDK J7200 09_00_01 users guide only show using make for building the PDK

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j7200/09_00_01_01/exports/docs/pdk_j7200_09_00_01_03/docs/userguide/j7200/getting_started.html#building-the-pdk

But that implies that I should I install the GCC tool chain and build with those. I don't understand if tiarmclang is supported or not. The documentation says that it is. Should I give up on tiarmclang?

Jeff,

The setup_psdk_rtos.sh script is a utility to prepare the RTOS SDK for multiple things. One part of the utility downloads the toolchain, another requires that the default rootfs and boot partition images are in the directory so that it can extract them for when you decide to make an SD card, or if you want to use NFS boot.

My suggestion right now would be to ignore the psdk_rtos_setup.sh, and lets get your setup working for your goals.

The first is that you wanted to build for the R5F. For this, please download the ti-cgt-armllvm_2.1.3.LTS into your SDK folder, like so:

cd ti-processor-sdk-rtos-j7200-evm-09_00_01_01/
wget https://dr-download.ti.com/software-development/ide-configuration-compiler-or-debugger/MD-ayxs93eZNN/2.1.3.LTS/ti_cgt_armllvm_2.1.3.LTS_linux-x64_installer.bin
chmod +x ti_cgt_armllvm_2.1.3.LTS_linux-x64_installer.bin
./ti_cgt_armllvm_2.1.3.LTS_linux-x64_installer.bin
# Installation runs, choose the default options. This will install the compiler in your sdk directory
cd pdk_j7200_09_00_01_03/packages/ti/build

make BOARD=j7200_evm allclean
make BOARD=j7200_evm pdk_libs -sj

Some things I didn't cover:

1) The PDK assumes the compiler is present in the SDK directory for the R5

2) In the past, we shipped the compiler with the SDK, now it's downloaded as part of the setup

3) J7200 SDK does not contain the setup psdk infrastructure, please see the J721E SDK for reference.

Let me know if this answers your query or if you have more!

Thanks,

Erick
