Boot-to-display

we want the fastest possible “boot-to-display” time. Could you kindly advise on the following for the Jetson AGX Thor:

Cold Boot Optimization: Are there official guidelines or best practices for Jetson Linux on Thor to aggressively strip down the SBL, Kernel, and Systemd to minimize the cold boot time to a display/camera application?

Suspend-to-RAM (SC7): If cold boot is too slow, we are considering utilizing Suspend-to-RAM for an “instant-on” experience. Does Jetson AGX Thor fully support SC7 deep sleep? Are there any known issues with waking up high-speed interfaces (like MIPI CSI or GMSL2 via deserializers) from the suspended state?

Thanks again for steering us in the right direction!

Linux_for_Tegra bootloader/uefi_bins/README_uefi.txt describes the 3 uefi_t26x_{minimal, simple, general}.bin that you can copy to bootloader/uefi_t26x_general.bin prior to flash to implement it.

In the bios you can reduce the uefi menu delay from 5 seconds.

# You can also check value with
sudo efibootmgr

# Change/set the value with
sudo efibootmgr --timeout number_of_seconds
