Testing the hardware connections The ECUcore 5208 primarily is designed as vendor part for the application in industrial controls Hence the ECUcore 5208 typically is integrated in a user specific baseboard To enable trouble free inspection of correct I O activation the Testing program iodrvdemo can be used This test program is directly tied in with the I O driver and allows quick and direct access to the periphery The testing program is preinstalled as executable home bin iodrvdemo on the ECUcore 5208 Moreover the program sources are included as reference application in the I O driver project See section 7 4 Start the Testing program iodrvdemo as follows cd home bin insmod 5208 spidev ko insmod pc5208drv ko iodrvdemo Figure 58 illustrates testing the hardware connection by using iodrvdemo EP 192 168 10 171 PuTTY L Lok For further intormation check http www uclinux org x mount t nfs o nolock 182 168 10 93 tftphboot mnt nfs lt gt cd mnt nfs s5z s insmod S208 spidev ko coot mnt nis insmod pces5z sdrv ko ront mnt nfs 5208 iodrvdemo Test application for SYSTEC ElUcore 3205 board driver Version 3 00 2006 2005 SYS I O Driver version KernelModule 1 00 UserLib 1 00 Hardware CFU Board 4218 00 008 CFU PLD 0 00 00H IO Board Config aoooH application ZO test digital I O and user switches IAC menu CD menu un EEPROM test un te

14. comment The definition can be adjusted for other time zones e Stack sizes of programs Programs being compiled for uClinux have a standard stack size of 4KiB Because there is no MMU there is no way to handle case where the stack size is insufficient In case of program aborts or worse kernel aborts or panics a stack set too small could be the reason To increase the application size a program called flthdr of the toolchain has to be used An example is m68k uclinux flthdr s 20480 romfs bin busybox This sets the stack size of the busybox application from the directory romfs bin relative to the current working directory to 20 KiB SYS TEC electronic GmbH 2008 L 1202e 1 Page 70 System Manual ECUcore 5208 Appendix A GNU GENERAL PUBLIC LICENSE The uClinux used on the ECUcore 5208 is licensed under GNU General Public License version 2 The entire license text is specified below A German translation is available from http www gnu de documents gpl 2 0 de html Be advised that this translation is not official or legally approved Additional SYS TEC system software and programs developed by the user are not subject to the GNU General Public License GNU GENERAL PUBLIC LICENSE Version 2 June 1991 Copyright C 1989 1991 Free Software Foundation Inc 59 Temple Place Suite 330 Boston MA 02111 1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document but changing it is not allowed
