I am using the new image version for xavier.

Linux ubuntu 5.10.65-tegra #1 SMP PREEMPT Mon May 16 20:58:07 PDT 2022 aarch64 aarch64 aarch64 GNU/Linux

I find that UEFI replaces the CBoot in Jetpack 5.0.1. But this brings up two questions that confused me.

  1. I want fast booting, But UEFI loading time and waitting time take so long. Is there any way to skip the wait below?
Jetson UEFI firmware (version r34.1-975eef6 built on 2022-05-16T20:58:45-07:00)
Press ESCAPE for boot options **  WARNING: Test Key is used.  **
......
  1. When I use the uart1 port, I also get the UEFI log above. Uart1 on our board is used to communicate with MCU, so we do not want to recevied any other information from this port. May I ask how to disable printing UFEI info to uart1 port ?

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

Hi,
Have you tried Jetpack 4 release? Would like to know if the custom board works with Jetpack 4 and uart1 also works as expected.
