Need to stream the data from multiple cameras in parallel.

Hello Experts,

Is it possible to do parallel streaming (6 cameras, per 2 lanes) in Jetson TX1 and TX2 BSP ??
What is major difference between Jetson TX1 and TX2 in point of driver and BSP view ??

I’ve seen the below link that they are able to stream the data using 6 cameras… is it default BSP support, we should modify the driver to enable the parallel streaming for the 6 cameras.

Can you please help to understand this ?

Hi,

The TX1/TX2 hardware is capable of streaming 6 cameras in parallel. There are some minor differences in the driver level between the TX1 and TX2. Hopefully you do not have to worry much about the platform side driver as Nvidia maintains and fixes bugs in their L4T releases. However the sensor driver is your responsibility and would require minor changes to work on TX2.

The main difference I can think of between TX1 and TX2 is the change from Kernel version 3.10 to 4.4. Hope this helps.

Hi Dilip,
Thanks for your reply.
I understand that TX1/TX2 HW supports streaming 6 cameras in parallel.
And how about the BSP ?
Whether the BSP supports this multiple streaming ?

Thanks for your help.

Yes titus,

The BSP has support 6 camera streaming as well. But it also depends on the sensor you intend to use. Not all cameras are configured for use in 6 camera mode. These configurations will be available in the device tree part of the BSP. You might require to tweak some files (device tree, sensor driver) here and there to suit your exact needs.

Okay Dilip, thanks your reply and your confirmation.

e-con Systems supports parallel streaming (6 cameras, per 2 lanes) in Jetson TX2/TX1.

e-CAM30_HEXCUTX1 is a Multiple camera solution for NVIDIA Jetson TX1/TX2 developer kit that consists of six 3.4 MP 2 Lane MIPI CSI-2 camera board and an adaptor board (e-CAMHEX_TX1ADAP) to interface with the J22 connector on the Jetson TX1/TX2. Each camera is based on 1/3" AR0330 color CMOS sensor from ON Semiconductor and an on-board image signal processor (ISP).

I purchased and tried the e-CAM30_HEXCUTX1. The setup is clean and well documented, support is okay with sometimes long delays in response. I think they are just too busy with the high demand in the market.

I am using to camera systems to demo an aggregated mobile 4G - 6 camera streaming solution.
