Hi all, I've a problem with the mini6410 board and its 7" touchscreen in a system based on Linux Ubuntu 9.10 OS This is my environment: Ubuntu kernel: uzImage_a70 from DVD (Ubuntu Karmic 9.10) Rootfs: generated with Rootstock with this command sudo rootstock --fqdn ubuntu --login ubuntu --password temppwd --kblayout it --dist karmic --mirror http://old-releases.ubuntu.com/ubuntu --seed xorg ts.conf file: module_raw one-wire-ts-input module pthres pmin=1 module variance delta=30 module dejitter delta=10000 module linear The directory usr/lib/ts0 contains the file: one-wire-ts-input.so (that I've compiled) In the directory /usr/lib there are these files: libts-0.0.so.0, libts-0.0.so.0.1.1 At the first boot the system run this code: export PATH=/bin:/sbin:/usr/bin:/usr/sbin mkdir /dev/input 2>/dev/null mknod /dev/input/event1 c 13 64 2>/dev/null mknod /dev/fb0 c 29 0 2>/dev/null mknod /dev/touchscreen c 10 180 2>/dev/null mknod /dev/touchscreen-1wire c 10 181 2>/dev/null mknod /dev/s3c2410_serial3 c 204 67 2>/dev/null export TSLIB_TSDEVICE=/dev/touchscreen-1wire export TSLIB_CALIBFILE=/etc/pointercal export TSLIB_CONFFILE=/etc/ts.conf export TSLIB_PLUGINDIR=/usr/lib/ts0 export TSLIB_FBDEVICE=/dev/fb0 export TSLIB_CONSOLEDEVICE=none if [ ! -s /etc/pointercal ] ; then ts_cal mv /pointercal /etc fi exec /sbin/init At the first boot the system recognizes correctly the touchscreen: 1Wire touchscreen OK TouchDevice: /dev/touchscreen-1wire xres = 800, yres = 480 and the procedure "ts_cal" is performed correctly (file etc/pointercal created) After this I login into Ubuntu but the touchscreen stops working: a. the command cat /dev/touchscreen-1wire work correctly b. if I call ts_cal or ts_calibrate return errors ts_config: no such file or directory or ts_open: no such file or directory or TouchDevice: (null) I don't understand where is the error, please can anyone help me?

Just a thought. Have you actually configured the links on the LCD to support the 1-wire interface? My LCD came with it configured to connect direct to the ARM touch screen interface. Once the links were swapped it works perfectly and a lot more stable than the ARM interface option. Dave...

Hi Ika, Have you used or built the kernel to support you video output? Looking at the info above I see image drivers for the 7" LCD. As I don't know anything about your video to VGA interface, can you tell us more about that so we can try to work out what is wrong. Thanks Dave...
