Failed to resume from the SC7 state

Hi,

I am using JetPack 6.2 (Jetson Linux 36.5) on the Jetson Orin NX 8GB Developer Kit. Except for the NVMe SSD, no other peripherals are connected. After resuming from the SC7 state (entered by running systemctl suspend) using the power button, the system reports the following error and then hangs indefinitely.
NOTICE: tegra_soc_pwr_domain_on_finish: exited SC7 successfully. Entering normal world.

Hi nano.wang,

R36.5 should be included in Jetpack 6.2.2 rather than Jetpack 6.2.

How did you setup the developer kit? With SDK manager?
How about the failed rate for the RAS error during resume?

Do you connect any devices(display, USB, PCIe, SPI, I2C..etc) on the devkit currently?

Hi Kevin,

Yes, it’s Jetpack6.2.2.

I flashed the developer kit using the l4t_initrd_flash.sh script rather than SDK Manager.

The issue is 100% reproducible. The RAS error occurs every time the system resumes from the SC7 state.

The only connected peripherals are the NVMe SSD and a serial console for logging. No display, USB devices, additional PCIe devices, SPI devices, I2C devices, or any other external peripherals are connected.

As you are using the Orin Nano devkit(P3768) with Orin NX 8GB module, please check if there’s the similar issue if you flash it through SDK manager.

We will also validate this on our local setup.

Can the hang condition only be recovered by resetting the board? (i.e. power cycle manually)

Hi Kevin,

The version I burned using SDK Manager indeed does not have this issue. The version I made myself has this issue. I mainly made some kernel modifications and adapted the Wi-Fi 7 module, but during verification, the module was not plugged into the device.
When a problem occurs, the system cannot be restored by pressing the power button, which should be powered off and then powered on.

Could you just flash with the official BSP package (w/o custom kernel customization)to verify?

Or disable it from device tree to check?
