Accompanying my patches for the MIPS Creator CI20 (Ingenic JZ4780), I have some patches that get Fiasco.OC booting on the Ben NanoNote (Ingenic JZ4720). Currently, I can get a task running that shows some data on the screen. More details about the Ben NanoNote can be found here:

(It is a "palmtop" device from around 2010 that was made in fairly limited quantities but unfortunately didn't get the attention it deserved that might have seen follow-on models, and many more units, being made.)
Unfortunately, the data I display on the screen isn't aligned properly. This isn't a fundamental problem since I was happily using the screen to emit bit patterns in order to debug the kernel while working to bring it up on the hardware.
Following up to this - sorry, my bad habit again! - this was actually caused by a slip-up when decoding values and showing them on the screen. In fact, the picture *is* properly aligned.
Now all I have to do is to try and get fb-drv working and then I can run the spectrum example. But I've updated the patches in the unlikely case that anyone else is really interested.
