Hello everybody, we're in the progress of porting Android on a Freescale i.MX28 board. We've got to the point where we're trying to make the touchscreen work with Android, so we've borrowed the patches from 0xdroid for tslib and compiled for our board.
Both tslib and the Calibration Test App from the donut branch work fine: http://gitorious.org/0xdroid/external_tslib http://gitorious.org/0xdroid/packages_apps_tscalibration We're now trying to get the integration code in frameworks/base working, but it's giving us a big problem. I've downloaded this patch: http://gitorious.org/0xdroid/frameworks_base/commit/04c8fcb888528659d58fb6f93b01fa892ee717a4 and applied successfully to our own donut-porting branch. Some rare times the system goes up and touchscreen somehow (that's another story) works: http://pastebin.com/Ty1cHhgR Unfortunately most of the times the system isn't able to start SurfaceFlinger and gets stuck into an infinite loop repeating something like: "W/SurfaceComposerClient( 1778): lock_layer timed out (is the CPU pegged?) layer=0, lcblk=0x40209020, state=00000043 (was 00000043)" http://pastebin.com/dBXCXZ4e The problem resides in the libui.so. I've broken down the patch into pieces and identified what causes the problem: - compiling libui.so by just adding the «#include "tslib-private.h"» in EventHub.h makes Android always regularly startup; - compiling libui.so by adding both the «#include "tslib-private.h"» and the pointer declaration «struct tsdev *mTS;» in EventHub.h makes Android fail to launch SurfaceFlinger most of the times. Does anybody know what could be causing the problem? Could we be missing something (we've noticed we're missing pmem support)? Any help would be highly appreciated, thank you.
