Renegade touchscreen

Recommended Posts

I have a Renegade ROC-3328-CC board, and trying to get the touch to work on the touchscreen (Typical resistive Touch screen 3.5" HDMI HAT type screen).  I'm using the Armbian_5.75_Renegade_Ubuntu_bionic_default_4.4.174_desktop.img, and everything is working except the touch on the screen.

 

Does anyone have success with this combination?

 

By reading through topics on the forum, it seems to me that I need to be on the mainline kernel (since it has fbtft and ads7846 drivers), but I'm not finding any packaged images using mainline that will support his board.  

Anyone have a mainline Image for the Renegade? 

 

I tried the Tinker images which are on Rockchip 3328, but they completely fail to boot.

 

Only next step I'm seeing is to build a custom kernel, or try to backport the fbtft +  ads7846.

everything is there.. just activate the needed modules and build your own kernel.. But probably none of us tested if it works on RKs kernel. Fire up a virtualBox with ubuntu, build kernel, try it, report and if everything works create a PR.

*RK3288.  It's a 32-bit quad core, the RK3328 is a 64-bit quad core, absolutely incompatible bootloaders/images.  I only bring it up so there's no confusion for anyone else reading.
