I would like to build custom boot-up logo and update on my device. I did follow this guide: http://docs.khadas.com/develop/BuildBootLogo/
But i didn’t know how to update it on my device. I saw: 2) Insert the USB disk into VIM device, then boot into U-Boot mode. How could i “boot into U-Boot mode”?
Dear @Terry, @Gouwa, I’ve tried this adb technique, everything works fine, without any error, but logo didn’t change. Please, is there any other command to try in adb mode? (VIM3) Is the syntax correct? (if= …) Thank you for any help, all the best, Tomas
