above, it is configure in jetson-agx-orin-devkit.conf ,I have upgraded the devkit by using flash.sh shell.I have not modify extlinux.conf. Is it right?

24

抱歉… 有點看不懂你想表示什麼.
extlinux.conf跟 jetson-agx-orin-devkit.conf沒有什麼關係…

Sorry, not quite sure what you want to ask here. How about you elaborate more about your question?
extlinux.conf has nothing to do with jetson-agx-orin-devkit.conf

25

I mean,I have not config TBCDTB_FILE=.I use r35.1 linux default config.Is it also Right?

26

You need to configure it so that your kernel dtb will be separate from your uefi dtb…

27

1.the uefi dtb should I use which device nodes?
2.If the kernel want to use like usb,can,the uefi dts can disabe the device node in the uefi dtb?

28

1.Can I disable all the device node if I do not want to use it int the boot stage,and enable the device node int the kernel dts?

I closed some device nodes in the tbcdtb,but the kernel produces exception int the kernel stage.

messages like above takes some times even if I close so many device nodes.The uefi can reduce some functions at the compile stage?

30

How do I modify the config options in the uefi code when compiling?
Looking forward to your reply.

Hi jasonGrave,

Actually, there is no 100% working method to decrease boot time now and we don’t guarantee UEFI would not crash if you just randomly remove things from UEFI.

If it crashed after your remove something, then it means you shouldn’t remove that.
