Freeplay CM3 GBA clone Kit.

I am back and tested with a fresh install on release 180330 that I use everywhere, not to introduce other error.

And I can confirm you, all engines running. The custom parameter in recalbox.conf is accepted and processed, as you see also in recalbox.log, without any modification on the kernel part and also without file mk_arcade_joystick.conf in /etc/modprobe.d ! The winner take's it all.

So you can put this ko in the next release.
Next digging from my part will be on ili934x driver, I think that Subs also was meaning this one for 60fps.

@Dragu tha'ts a good news.

As you can see, the AlekFULL theme comes pretty well under this small screen. I will at a certain moment make some improvement on the fonts (text that is hidden for the moment.)

Why you dont see it? Because the GBA has a cutout frame off 3" and display has 3.2". Original GBA display had 2.8".

Main problem from waveshare32b.dtbo driver is low speed but also no possibility to shift the viewing area or compress.
Therefore, next step is ili9341 that has all this features and is also already in the Recalbox package.

@dragu i remember @Flavor was colplaining about kodi ...

[Dragu]

@Substring
But Kodi I am able to load. Now in general I dont use it, so maybe something.
But I have another question for you. The line in config.txt

dtparam=spi=on

does this line load's spi-bcm2835.ko ? Or something else, its in relation with the fb-ili9341 driver.

[Substring]

@dragu no the libe triggers some hardware functionnality, which can in turn make the kernel load the required ko in a.plug-n-play style

[Dragu]

@Substring
With the ili9341 driver I may have reached my limits, but I also cannot find the executable con2fbmap in the recalbox bin.

[Substring]

@dragu prolly it doesn't exist

[Dragu]

@Substring
https://manpages.debian.org/jessie/fbset/con2fbmap.1.en.html

[Substring]

@dragu what's the point of it ?

[Dragu]

@Substring
I found a copy now. It's an utility that should write a framebuffer to the device by a certain driver. So more for testing. ili9341 is writing only newly changed parts of the framebuffer to the display, as waveshare driver is doing the whole. This should be about real 60fps instead of 30fps. As I am not able to compile and have no Linux system for this, I will just use what exists without special branches for my toy.

[Substring]

@dragu are we talking about https://github.com/juj/fbcp-ili9341 ?

[Substring]

you shouldn't have THAT many framebuffer devices ! just /dev/fb0 or /dev/fb1. The latter is usually the SPI one, so make a dirty assumption

[Dragu]

@Substring
WIth fbcp-ili9341 you are totaly right, as Juj has a working version of this, but you find no compiled executable for Freeplay from him. Perhaps I can ask him for this, if he want to share.

[Dragu]

@Substring
Anyway I get more and more confused about this, just a copy of dmesg. Means that waveshare32b.dtbo load fb-ili9340, with in config

[Substring]

@dragu have you read https://github.com/juj/fbcp-ili9341/blob/master/README.md#installation ? No dtoverlay should be specified, the driver handles everything

[Dragu]

@Substring
Yes. More than 10x
But we have not fbcp-ili9341, and my head too much small to build this.
There is also this page that described the display area with new adapted viewport :
https://github.com/juj/fbcp-ili9341/blob/master/freeplaytech_waveshare32b.h

[Substring]

@dragu I haven't checked in-depths how it works, but you might simply build it in raspbian and copy it over to recalbox

[Dragu]

@Substring
Now, problem, what version of Raspian should I need to stay compatible with Recalbox ? I have spare SD's and can always shoot one for my bartop if it will work. Otherway my spare PI's are used up.

[Substring]

@dragu the most "secure" version would be one with kernel 4.4
