I have finished the compiling of CoreELEC 9.2.1 ,The information is as follow：

============================================================================
[084/288] [DONE] install image
Successful build, creating image...
============================================================================

Q1：Why the progress number is just 084,not 288?

Pls help.

A1: Interesting, I didn’t saw this before. If image was build then just ignore it.
A2: Those are separated kernel and system files for 2 specific boards. Ignore them.

Before use make image command. I input “PROJECT=Amlogic ARCH=arm tools/download-tool” to download packages in sources folder.

I never run this step. Just make or make image.
