Oh! I didn't realize, lzo is in a sorry state. Our only reason for using lzo over lzma, was purely a boot-up speed race. (Thinking with the am335x single core at 1Ghz..) Does OE-Core have proper support for lz4 as a replacement? Or just in general lzma is the most recommended? Regards, -- Robert Nelson https://rcn-ee.com/
