USB Unresponsiveness Issue on Jetson AGX Orin During EMC Immunity Tests

Hi,

We are working on a project that involves a carrier board for the Jetson AGX Orin SOM and a separate IO hub board which will be connected to the carrier board through USB Cable. While conducting some EMC immunity tests (ESD, EFT) on the IO hub board, we encountered an issue where all USB peripherals connected to the AGX Orin become unresponsive.

This includes USB peripherals connected to the USB hub on the IO board as well as those on the carrier board. After this event, the USB functionality does not recover, although all other functionalities and peripherals of the AGX Orin SOM continue to work fine.

We are unsure about the possible cause of this behavior. Is there a way to detect this unresponsive USB state and recover the USB interface in such incidents?

Thanks

Hi,

If you are designing a custom base board, then it means some adaptation configurations are needed.
Otherwise, your board may not work fine.

For Orin AGX series, you could refer to below document
https://docs.nvidia.com/jetson/archives/r36.3/DeveloperGuide/HR/JetsonModuleAdaptationAndBringUp/JetsonAgxOrinSeries.html?highlight=universal%20serial%20bus#jetson-agx-orin-platform-adaptation-and-bring-up
(please be aware that above link is for rel-36.3/jetpack6.0)

This document includes below configuration

  1. pinmux change & GPIO configuration
  2. EEPROM change as most custom boards do not have an EEPROM on it.
  3. Kernel porting
  4. PCIe configuration
  5. USB configuration
  6. MGBE configuration
  7. RGMII configuration

Thanks!
