Hi I'm new to Kernel 2.6 and OF.
I'm using a ADS5121 board with kernel from denx (ads5121 branch from linux-2.6-denx). According to my dts file both PSC3 and PSC4 should be accessible through /dev/ttyPSC0 and /dev/ttyPSC1 respectively. When I simply try to run: "$ echo "Hello" > /dev/ttyPSC*" I can't see any data coming out from the ports. And when trying to initialize the ports using termios commands I'm getting the Error "Inappropriate ioctl for device". I'm not even getting a negative voltage on the TX Pin (idle state). But I can see the driver ttyPSC with major 204 in /proc/devices and I can also open the device successfully. I am also able to configure either port as CONSOLE in U-Boot so the Hardware is ok. Any ideas? Many thanks, Stefan _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
