My goal for the beginning of 2007 is to launch=20 a project for 4 french studiants : a box with Linux embedded and a usb=20 camera. The embedded application will analyse the movies in Real time=20 and lead a mobile machine with CAN-BUS. Now i play with Xeno for my knowledge (without specific hardware) : a=20 little linux installed in a usb key with a little embedded distrib =20 - vanilla kernel 2.6.16 with patch for usb [.config is joint] - Xenomai 2.1.2 - essentially BusyBox - for xenomai : only "latency" directory and libs in usr/libs I have checked "SMI woraround" for the kernel. In BIOS I have UNchecked "legacy usb". =20 my Desktop PC (a AMD ATHLON) can boot with this little vanilla kernel and 1/ a little embedded distrib of my own OR 2/ a complete mandrake 9.1 on a partition of a classic hard disk I have 2 differents problems when I lauch this : 1/ with the linux embedded directories on the usb key high latency > 100 us are ok ? perhaps usb work is not compatible with RT ? 2/ with the complete mandrake 9.1 : it crashes X after 1 or few minutes. What is the relation between X and Xenomai ? Is Xenomai compatible with X ?
