Hello TI support

We are using TDA4VM board.

We want to know whether we can use ROS on GPU side and do you have some experience to build ROS on TDA4VM?

Our SDK is:

ti-processor-sdk-rtos-j721e-evm-08_00_00_12
ti-processor-sdk-linux-j7-evm-08_00_00_08

Hello,

Please refer to:

https://software-dl.ti.com/jacinto7/esd/robotics-sdk/latest/docs/source/README.html#git-repository

GPU cannot be used yet and we have not tried it.

Regards

Hemant

Hello Hemant,

Thank you for your reply.

Let me double confirm 2 points.

1) Based on your reference, TDA4VM is support ROS Medodic. Is my understanding correct?

2) If TDA4VM is supporting ROS Medodic, as I know ROS Melodic Morenia is primarily targeted at the Ubuntu 18.04 (Bionic).

However, as I confirmed on my board, the linux distribution is Arago.

So I'm confused which is the correct linux distribution. Can you please confirm?

root@j7-evm:~# cat /etc/os-release
ID=arago
NAME="Arago"
VERSION="2020.09"
VERSION_ID=2020.09
PRETTY_NAME="Arago 2020.09"

Hello Hemant

i just realized the link you shared is for SK-TDA4VM board, but we are using different product.
We are using TDA4VM including J721EXCP01EVM and J721EXSOMXEVM.

My understanding is they are 2 different hardware. please confirm.

Hello Li,

Your understanding is correct about the hardware. The SK-TDA4VM and J721EXCP01EVM+J721EXSOMXEVM are two different products. Currently we support the Robotics SDK linked by Hemant on both SK and EVM boards, but in the near future (SDK 8.2 release) we will only support Robotics SDK on the SK board.
You are also correct about ROS Melodic targeting Ubuntu 18.04. We do not have support for running ROS directly on our Arago distro. However, in the Robotics SDK, we provide a Docker container that can run Ubuntu on top of Arago. This allows ROS Melodic to run on the TDA4VM inside the Docker container.

Regards,

Takuma

Hello Takuma

Thank you for your reply. Let me try whether we can run Docker container which run Ubunta on top of Arago.
