Hi there,
Ok so I did ping him with the link, so shouldn’t be too much longer. I get that error (403) from a wacky cut and paste sometimes.
Documentation is Key, You will see there is a couple of us on here, that beat that to death on this tech

Not that it is comfort but you are NOT alone in your quest and similar endeavors are being undertaken…
"Hi! I'm using the reComputer Jetson J1010 with JetPack 4.6.6 (L4T 32.7.6). I want to use the Raspberry Pi HQ Camera (IMX477) and I’ve already removed the R8 resistor as recommended.
However, jetson-io.py is not working on the J1010 carrier board, and I cannot configure the CSI camera from the graphical interface.
I found some .dtbo files in /boot, including:
/boot/tegra210-p3448-all-p3449-0000-camera-imx477-dual.dtbo
/boot/tegra210-p3448-all-p3449-0000-camera-imx477-imx219.dtbo
/boot/tegra210-p3448-common-imx477.dtbo
Can you please guide me on how to enable dual IMX477 cameras on J1010 via extlinux.conf or another method that works for JetPack 4.6.6?
Thank you in advance! "
I’m fairly confident you will get it going…with the right help.
