Hi varun_pandithurai,

Are you using the devkit or custom board for AGX Xavier?

Reducing the boot time depends on your use case about what you want to keep and what you don’t need. You could refer to the serial console log from power on and check every debug message to find which driver/service takes long time for boot up.

You could refer to the following instruction to disable UART prints.
Boot Time Optimization — Disable Console Printing over UART

Hi @KevinFFF,
I did as per the document but Console printing over UART didn’t disable

You could refer to the following topic to disable combined UART.
Disabling UART debug prints over ttyTCU0 - Jetson & Embedded Systems / Jetson Xavier NX - NVIDIA Developer Forums

hi @KevinFFF,
I tried the the methods in the above link but still not able to stop console logs.
I am using a custom carrier board which is a clone of DevKit.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Could you help to provide the current serial console log from power on?
