Upgrading the Jetson Nano to "Super"
By Aaron Marburg

In late December, Nvidia announced their Jetson Nano “Super”, announcing a dramatic increase in ML performance at half the cost of the existing Nano. Since we just bought our Nano in October, at first I was disappointed that we had just missed out on a major system version (and paid more for the privilege).
As I dug into it, I realized, along with others, that the Nano “Super” was in fact the exact same hardware (as the existing 8GB Nano) with a new NVP mode. It’s a software upgrade (and yes, a hefty price drop)!
Since our test Nano was running Jetpack 6.1 already, I had hoped that I could get the new NVP models by a simple apt-get upgrade
, but the BSP notes say:
MaxN mode is available only when flashing with the jetson-orin-nano-devkit-super configurations.
so there must be some modifications in the earlier phases of the bootloader.
So … back to SDK manager, and I re-flased the Nano with “6.1rev1”, and lo and behold:
> nvpmodel -p --verbose

So the new MaxN
mode exists. I assume the max frequency of “9223372036854775807” means effectively “as fast as possible”?
