Compile with the following documentation
The burning tool is as follows
- Upgrade on Windows PC with USB-C Cable （update Aml_USB_Burn_Tool_V3.2.0）
OK
i tried running the commands
one of the commands"$ sudo apt-get install unzip lib32z1 libx11-dev lib32z-dev ccache gitk xmllint libxml2-utils libssl-dev
" Is giving me error that xmllint file does not exist.
Also there is a lot of confusion between which commands have to be entered in the terminal and which ones in the shell
The toolchains commands have to be executed in the terminal of my computer,right??
To download the android source code, the commands also have to be entered on the computer??
In this page https://docs.khadas.com/products/sbc/vim1s/development/android/build-android#build-u-boot to build U-boot the commands have to be entered in adb shell or the terminal of the computer??
In the page VIM1S Build Android [Khadas Docs] the commands have to be entered in adb shell or terminal ??
Download the Android environment, Android source code, and Android compilation, please read the three detailed documents in the link below

Please verify and feedback the results.
Sorry for the late reply.
I tested the image however only the logo appears on the screen, I recorded a video and here is the link https://drive.google.com/file/d/1WYjjM4lmhmfp-GPzA5Xtcpq3bUQaVRPY/view?usp=share_link though the video is 24 seconds long I waited for 10 minutes but there was no signal to the display.
Hello, please use adb shell to help us grab the kernel.log of dmesg and analyze it, because at the end of the video, there is no signal prompt.
The grab command is as follows, please provide us with the log, thanks
console:/ $ su
console:/ # dmesg > /storage/kernel.log
Ok i think I have to enable developer mode on the khadas vim to extract the log as i am getting error :
/system/bin/sh: adb: inaccessible or not found
You should do adb pull /storage/kernel.log under C:\Users\Archana\Downloads\tools>
You should still take out the dmesg log as I mentioned above, you will take the log to the desktop, the following command
C:\Users\Xiong>adb pull /storage/kernel.log C:\Users\Xiong\Desktop\
I have attached the link to the kernel file, it is in txt format as I had to copy everything in it into notepad. https://drive.google.com/file/d/1oBDYIFVfrk7REm2kA9ELkcYYlvSe_BXA/view?usp=share_link
Dis you figure out the problem ??
Hello, is the log you posted above when the HDMI display is not plugged in? Also, are you using the firmware we sent directly or using your own DIY firmware?
