AGX Orin Custom Carrier Board Boot Time Issue

Hello Team,

We are currently working on a custom carrier board with AGX Orin, and we have observed that the boot time is longer, approximately 2 minutes and 20 seconds. In comparison, the AGX Orin Dev kit shows a boot time of around 50 seconds.
We have not made any modifications to the L4T packages and flashed the default Jetpack 5.3.1, but the extended boot time persists.

We would greatly appreciate any assistance or guidance to address this prolonged boot time.

Thank you,
Parashuram

Hi Parashuram.Biradar,

We do not have this release.
Please refer to this page for the Jetpack version and let us know what are you using.

Could you enable the timestamp in serial console and compare the boot up log between the devkit and your custom board to check what takes time in your case?

Hello Kevin,

Thank you for your response.

My apologies for any confusion. Currently, we are working on the default L4T 35.3.1 with JetPack 5.1.1. I have attached both the EVK log and the Custom Board log for your reference. Could you please provide guidance on how to optimize the boot time of our custom carrier board?

Your assistance will be highly appreciated.

I would suggest you could enable the timestamp in serial console log first to check the time used for different boot stage.
Then, please refer to the following instruction.
Boot Time Optimization — Jetson Linux Developer Guide documentation (nvidia.com)

Please note that the methods in this document are specific to kernel part. You should disable the device nodes and kernel configs which are not used in your use case.

Hello Kevin,

Could you please let me know how to enable the booting timestamp. My concern is that, without any modifications in the L4T 35.3.1 package, the default package is flashed. However, the booting time seems unusually long. If I enable additional drivers and nodes, it might take more time than the EVK. Ideally, it should have a similar booting time to the EVK unless modifications are made.

Regards,
Parashuram

It depends on the serial application you used.

Please refer to the following thread to enable timestamp in minicom.
