Hi,
The image file is generated by compiling the kernel source code. How can the image file be flashing into TX 2 in the JetPack4.2?
Because I can’t start the system after flashing the Image using the following steps:
Thanks
Hi tianying414,
Your steps is correctly. On steps 4, can you flash success?
Please share your error logs. Thanks!
Hi,carolyuu.
On step 4, I can refresh successfully, but the system can’t start.
The following are some of the contents displayed on the monitor at power on.

tianying414,
Your log is being truncated by forum. Please attach it as an attachment.
Why do you file a separate topic? You already had one in 1061997 and you didn’t reply it.
Hi,WayneWWW.
I added an attachment.
Feel that the individual topic issues will be clearer. Sorry, the previous reply seems to have been deleted.
Thanks.
tianying414,
Actually, your system boots successfully. But the display manager does not. Could you share your dtb and kernel image with us? Also, please kindly share what you’ve modified. Thanks!
Hi,WayneWWW.
I added the DTB and kernel image and the modified code to the attachment.
I have also tried this approach, flashing the image generated by compiling the unmodified kernel source code into TX2, and the system failed to start up properly.
Thanks.

Hi tianying414,
It seems we could reproduce your issue on our side. But we are not sure the reason now.
Could you share what you’ve modified as a patch here? I would like to investigate it. Thanks.
Hi,WayneWWW.
I did not modify the patch, only modified the source files in the attachment. Later, in order to troubleshoot the problem, I used the kernel source code and did not make any modifications to the source code. I flashed the generated image file to TX2 and found that the system could not be started normally.
My host system version is ubuntu16.04
Thanks
→ I used the kernel source code and did not make any modifications to the source code.
Could you share your step of building kenrel image?
→ I did not modify the patch, only modified the source files in the attachment.
Yes, I know… I would like to know what you’ve changed so want you to share it as a patch.
But it sounds not matter now since the original source also has this problem. Please share the step first.

Notice a minor difference here.

<s>make O=$TEGRA_KERNEL_OUT zImage -j4</s> -> We are not building zImage. please refer to l4t documentation.

Hi,WayneWWW.
I follow your prompts and nvl4t_docs steps, the system can be started after compiling and burning the image.

I am not familiar with tlv320aic32x4. According to your log, it looks like it needs a correct regulator for iov.
You may find a separate for tlv320aic32x4 since the topic here is only for flash/booting issue.
Also, below log is not fatal.
