Very nice blog Mikhail! And it looks to be great work!
Thank you for the complimentary things you said about RTEMS features.
I have a few questions.
+ Is this going to show up in the Qt free edition?
+ Any ideas on what RTEMS could do to improve our side of the
hosting Qt equation? Graphics has always been a challenge.
FWIW I took a stab at estimating porting Qt a few years ago. It is a large
body of software and a lot is just not appropriate for most embedded
I got a reasonable subset to build but never got funding to do the actual
I am quite thrilled your effort was more successful.
