Hi, i already have a pcDuino1 that i can't use with my touchScreen (a egalax usb driver) because the original Kernel give by you (linkSprite) don't take in charge it. For this reason i bought a udoo card with a imx6 quad core processor. Now i can use my touch screen with it (no need to modify the kernel !) . I'm interested by your acadia card but i would know if now your version of ubuntu take in charge egalax touch screen driver (with no kernel modifications) ? This version of ubuntu is build with hard Float ? Do you plan to provide a android version for this card ? Is possible to have a tutorial to cross-compil qt5.4 on it ?
