Dear supporter,

I have 1 Jetson ORIN Development kit
I have a doubt related to performance between eMMC and NVMe
the behavior are:

  • with eMMC:
    step1: I used SDK manager, flash OS and component into eMMC => it boot up and work normally, power mode showed from 15W, 30W, 50W, MAXN
    step 2: I used ./flash.sh command and flash it as ORIN NX 16GB in to eMMC: ‘sudo./flash.sh jetson-agx-orin-devkit-as-nx-16gb mmcblk0p1’
    => it can boot up normally but powermode showed: 15W, 25W, MAXN

  • with NVMe:
    step 1: I used SDK manager, flash OS and component into NVMe => it boot up and work normally, power mode showed from 15W, 30W, 50W, MAXN
    step 2: I used ./flash.sh command and flash it as ORIN NX 16GB in to NVMe: ‘sudo./flash.sh jetson-agx-orin-devkit-as-nx-16gb nvme0n1p1’
    => it can boot up normally but powermode showed: 15W, 30W, 50W, MAXN

so, why there are a different results(power mode) between eMMC flashing and NVMe flashing after step 2?!
Could you help me clarify it!

Hi nguyennhatanh1805,

For Orin devkit, please just use jetson-agx-orin-devkit.conf as your board config.
Power mode configuration would relate to different modules.

Hi Kevin,
Thank you for your reply!

I want to emulate ORIN NX 16GB on my Jetson ORIN Dev kit, so that I do the steps I mentioned above becuase I cannot order a actuale ORIN NX 16GB kit right now
So, I just confuse about why there is different behavior between flashing into eMMC and flashing into NVMe, could you enlighten me!?

I have no idea about why there’s difference between flashing into eMMC and NVMe.

but… They are just the default powermode used for different scenarios, and you could also create your own through modifying /etc/nvpmodel.conf.
