Hi,

  1. Please try to enable UEFI log by rebuilding the UEFI binary and replace the original binary with the debug build one.

  2. Are you able to reproduce same issue on devkit?

4

1、 UEFI we failed to compile. Could you please provide us with some steps to compile UEFI.
2、devkit has the same problem.

5

Could you share the exact steps you are using to reproduce this issue on devkit?

6

Steps to build UEFI :

7

The PC sends a hexadecimal packet every 500 milliseconds. When the serial port receives the packet, it inevitably restarts
55 0D 04 33 65 E5 74 7F 40 3C 36 CE 9B 55 0D 04 33 65 E5 75 7F 40 3C 43 A0 B4 55 1D 04 DF 65 E5 76 7F 40 3C 37 72 39 61 73 38 73 65 6B 76 4B 62 74 43 4E 63 00 EA 0E

8

My previous question is how did you reproduce this issue with devkit? Do you have any special setup?
And I don’t think your PC needs to send packet to reproduce issue
 or you must wait for PC to send packet to restart?

9

Our application scenario is that the serial port is used to dock with DJI’s UAV. When the UAV is powered on, it automatically sends packets to the serial port, resulting in the constant restart of the module. This packet is the packet that we simulated to confirm would cause the restart

10

Hi,

To confirm, so if you don’t enable packet to send during boot up but do it later in kernel, then you won’t get reboot?

11

Yes, that’s right

12

Hi,

Could you create another dtb file which disabled UART1 in it and assign it to your “TBCDTB_FILE”?
This will disable UART1 in UEFI.

13

Is the device tree compiled by the kernel?

14

p3668.conf.common
DTB_FILE=tegra194-p3668-all-p3509-0000.dtb → this is for your kernel.
TBCDTB_FILE=tegra194-p3668-all-p3509-0000.dtb → this is for your UEFI.

Create a new one which is based on tegra194-p3668-all-p3509-0000.dtb but with UART1 disabled.

15

Our kernel uses tegra194-p3668-0001-p3509-0000.dtb, or modify the file p3668.conf.common?

16

Modify p3668.conf.common
 We don’t care about your kernel. What we are doing now is disable UART1 in UEFI.

If you still don’t understand what I am talking about, please ask. I feel the last 2 comments you replied showed you don’t understand what we are doing now


17

Okay, I’ll try. Thank you.

18

how to update uefi dtb,the cmd is right:sudo ./flash.sh -k bootloader-dtb jetson-xavier-nx-devkit-emmc mmcblk0p1

19

Or you can directly run with full flash.

20

However, if the log copy is the following path, the test problem still exists, and the update is not successfulcopying tbcdtbfile(/home/amoymn/nvidia/nvidia_sdk/JetPack_5.0.2_Linux_JETSON_XAVIER_NX_TARGETS/Linux_for_Tegra/kernel/dtb/tegra194-p3668-0001-p3509-0000.dtb)
 done.

 done.
done.

21

Could you clarify what did you change in your board config?
