As a result of the pricing I’m going to predict a strong surge in the interest of the Jetson Nano SBC. As a consequence I’m going to also predict a much stronger interest in your channel over the next 6 months. I’d recommend for you to be thinking of projects. Write this down because I’m seldom wrong. The Nano just needs a liitle more main stream promotion. You’ll be able to afford that Indian Scout Bobber in no time, and perhaps a compantion to Mr fire extinguisher.

your channel is the best guide for Jetson nano :) , Is performance on USB connected Hard disk affected by USB connected camera are they connected via USB HUB to processor?, as you have both peripherals can you check and show its performance?

[@JetsonHacks]

Thank you for the kind words. Yes, all of the USB peripherals effect the performance. Even though there are 4 USB 3 connectors, there's only one USB hub onboard which they all go through. This means you're limited to the limits of USB 3 (theoretical 5 Gbps (540 MBs)). Each USB 3 peripheral 'reserves' it's bandwidth when it's enumerated, so sometimes everything acts differently than what you'd expect. Thanks for watching!

[@AndriusJankauskasJankiz]

Will try this out definitely! Also wanted to ask, could you show how to build kernel modules for unsupported USB devices? Specifically I have a RTL8812AU wifi adapter that I got working on desktop Ubuntu and RPi but failed to *make build* because of missing kernel headers. I assume "Step 1" in your video would build the kernel and include everything but I'm yet to try it. Any input greatly appreciated

[@JetsonHacks]

I don't have that WiFi adapter, so it's hard to tell what you need to do. Typically you would have to get the kernel sources, then make and install modules (the buildKernelAndModules has a script for that). You do not have to rebuild the kernel Image. You may also need to install the firmware for the RTL8812AU which can be a little trickier if the linux-firmware .deb doesn't have it. Thanks for watching!

Hi Jim, my Jetson Nano is shutting down when I try to run camera and Lidar both. I have connected with Lipo battery of 4A, 2200mah,11V and 14.43Wh. I'm using buck converter to step down(4A, 5V) the voltage. If I unplug Lidar then it's working fine but shutting down if both connected. And I'm also able to run both with 5V, 4A adapter. Can you tell me where the problem is? Thank you so much. :)

[@JetsonHacks]

do not know where the problem is. However, it seems unlikely that your battery solution is actually providing 4A. A buck converter, while efficient, will still cause some power loss (usually a little >10%). Also, the claim that the 2200mAh battery provides 4A seems odd. If the battery is 1C, you would expect 2.2A, if 2C you would expect 4.4A. Sometimes the manufacturers fib a little, or the battery might be a little older and not provide that much current.

[@simonbunn5841]

This is out of date already. Cloning the git has no buildkernel.sh and trying to run the copyRootToUSB fails as it does not understand the -v switch with the USB disk drive name. Follow the instructions up to build kernel, then skip to the instructions on github which is to run ./addUSBToInitramfs.sh, partition the drive and format, and create an additional swap drive in the 10 GB of space you left at the end of the partition, selecting 'other' and 'swap file' in the partition options. You must reboot your Nano at this point then come back to this guide and run the copyRootToUSB with the -p command and use the /dev/sda1 or whatever name you drive has taken. Then you can continue the guide for changing /boot/extlinux/extlinux.conf again putting in/dev/sda1 if that is your drive. You must also change to this line INITRD /boot/initrd-xusb.img Worked for me

With the advent of SSD the best practice is to use a swap file when necessary. The advantage over a swap partition is that the swap file will move around the disk as it is written and deleted.
