Hi,

First of all, yes we need this. The bootloader needs it.

In the first trace you are missing JBIC, which is a patented image compression algorithm similar to JPEG.

You can disable support for that. Check the documentation for something like —-without-jbic.

On the second one, it did not include the headers for zlib correctly.

I suppose that cannot be disabled, because many algorithms depend on it.

Best,
-Michael
