Fpga holoscan cameras lattice

Hi,

In our project we want to evaluate the Hololens Bridge on Jetson AGX Thor
In our final project we will have:

  • AGX Thor
  • Lattice CertusPro-NX FPGA

So to get near our final product we wanted to use the CPNX100-ETH-SENSOR-BRIDGE HSB Bridge Board with the LI-IMX274-MIPI-D-HOLOSCAN-090H camera board as explained here:

  1. Will it work on the NVIDIA Thor AGX dev kit?
  2. Do you have some reference cable to connect HSB to Thor with this setup?
  3. Will it be possible to stream 2 cameras at the same times?

However here it is clearly specified that:

JP7.0.0 release currently supports only the Leopard imaging VB1940 Eagle Camera.

What will be the limitation to use the Lattice on AGX Thor with IMX274?

Regards.

Hello @XamiX,

Your questions are very similar to this other post, its cool to see the adoption of holoscan across multiple projects.

As I mentioned on that post, holoscan support is official for NVIDA Jetson Thor Devkit.

Regarding your question about streaming 2 cameras at the same time, do you mean the 2 cameras that connect to the bridge or do you mean connecting 2 bridges ?

best regards,

hello XamiX,

that’s not supported, so far, JetPack 7.0 support CoE (CSI over Ethernet) camera sensor only.

Hi,

I mean only 1 bridge with 2 cameras, but I got my answer it’s yes.
I do not see any limitation to connect another bridge also as it’s IP and as such just need to get different IP/MAC to connect multiple bridges.

What is less obvious is the availability of drivers and the ports to use on NVIDIA Jetson AGX Thor devkit.

What are the limitation to use CertusPro-NX Sensor to Ethernet Bridge Board with LI-IMX274-MIPI-D-HOLOSCAN-090H on this devkit?

  1. Can we connect the Lattice HSB with the QSFP port on the Thor and got image from the IMX274 connected on the bridge?
  2. If not, are we forced to pass through Ethernet port with SFP to Eth converter?
  3. Do we need to develop driver or some specific configuration file like to get accelerated SIPL networking as I can see SIPL accelerated network python example on AGX Thor with Li VB1940 camera here:

$ python3 ./examples/sipl_player.py --json-config ./examples/sipl_config/vb1940_dual.json

@JerryChang It seem possible to get IMX274 on AGX Thor as it is said here:
AGX Orin or AGX Thor with IMX274:

$ python3 examples/linux_single_network_stereo_imx274_player.py

So what are the needed connections?

Regards.

hello XamiX,

to clarify, this is for AGX Orin,
AGX Thor support with VB1940 so far.
