I have 3 questions related to your new product - Jetson Orin Nano.
In the specs you mention “8 lanes MIPI CSI-2 D-PHY 2.1 (up to 20Gbps)” which is 2.5Gbps per lane. But D-PHY 2.1 is capable of 4.5Gbps as far as I know. Can you explain what causes that difference?
Jetson Orin Nano Developer Kit carrier board includes two 22-position flex connectors to connect CSI camera modules, that support CAM0: CSI 1x2 lane and CAM1: CSI 1x2 lane or 1x4 lane. Does it mean that only 6 MIPI lanes are usable on the Developer Kit? Can 1x1 lane camera be used as either CAM0 or CAM1?
Jetson Orin Nano comes without SD card support, but Jetson Orin Nano Developer Kit has a slot for SD card. Can you explain how does it work?
>>Q1
it’s correct that Orin series has moving to DPHY-v2.1, however, the bandwidth remain the same as 2.5Gbps per lane.
>>Q2
that’s due to 4-lane configure on CAM0 is NOT working now, additional fixes are necessary to enable that.
each CSI port, (i.e. CSI-A) support x1 or x2, it combine two CSI ports (i.e. CSI-A/B) to enable x4 config.
so, 1-lane configuration is supported.
