Issue on power ramp Xavier NX GPU

Robotics & Edge Computing Jetson & Embedded Systems Jetson Xavier NX

Hello,

I am experiencing a critical issue with the GPU power-on sequence on a Jetson Xavier NX.

When the GPU (GV11B) powers on, the instantaneous current draw is too high, causing my custom board to reset due to power supply overload. This appears to be related to the aggressive power-on ramp when the GPU transitions from idle/off state to active.

  • Platform: Jetson Xavier NX
  • GPU: GV11B (tegra_gv11b)
  • Issue: Excessive inrush current during GPU power-on sequence

Is there a supported way to control the GPU power-on ramp through device tree properties?

Can the GPU power-on sequence be modified to include:

  • A startup delay before GPU initialization
  • Progressive frequency/voltage ramping
  • Current limiting during power-on

Are there any recommended approaches for managing GPU inrush current on custom carrier boards with limited power delivery capability?

I would appreciate any guidance on implementing a software-based solution to smooth the GPU power-on current draw, either through device tree configuration, driver modifications, or runtime power management settings.

Thank you for your assistance.

Best regards,
Yannick

Hi,
For further suggestion we would need to replicate the issue. Please put the module to Xavier NX developer kit, flash Jetpack 51.5, and test on this setup. See if you observe the issue. If yes, please share us the steps and we will try to replicate it on developer kit.

Hello ,
I can’t test this setup because i have a poe camera and i neet the network to stream . I can only test it on my custom board . Is there a way to limitate the current on cuda gpu start ?

Thanks

Hi,
You can adjust over-current limit of INA3221. Please check the section:

Jetson Xavier NX Series and Jetson AGX Xavier Series — NVIDIA Jetson Linux Developer Guide 1 documentation

Is this component on the som or on the eval board ? because i can’t see it

Hi,
It is on SoM.
