<p>Imported from Wayback via edit</p> <p><b>New page</b></p><div>== Troubleshooting from the command line ==<br /> <br /> &#039;&#039;&#039;Q:&#039;&#039;&#039; I just picked up a MeasurementComputing PCI-DIO24 card and am having trouble getting it setup. I notice that in RDadmin when I define the new device in &quot;Switchers GPIO&quot; as Local GPIO as layed out in the GPIO.txt, the default device path is /dev/gpio0. The problem is that /dev/gpio0 doesn&#039;t exist. <br /> <br /> <br /> &#039;&#039;&#039;A:&#039;&#039;&#039; The PCI-DI024 cards aren&#039;t supported in recent Linux Kernels, so it may not work for you.<br /> If you have an old kernel: Sounds like you don&#039;t have the GPIO driver turned on. You can get that from the Rivendell download page. Install it, enable the &#039;gpio&#039; service and you should then have a &#039;/dev/gpio&lt;n&gt;&#039; device node to correspond to each MC card in your system, along with entries in &#039;/proc/driver/gpio/&#039; to show you the status of each.<br /> <br /> You can check these by opening a terminal and running the following to check if the gpio devices have been created:<br /> <br /> ls /dev/gpio*<br /> <br /> This will return something like this:<br /> <br /> gpio0<br /> <br /> To check the status of the device run the following in a terminal:<br /> <br /> ls /proc/driver/gpio/*<br /> <br /> This will return something like this:<br /> <br /> card0<br /> <br /> You can then run the following to see the status of card0:<br /> <br /> cat /proc/driver/gpio/card0<br /> <br /> == Troubleshooting with GUI utility program RDGpiMon ==<br /> See the [[RDGpiMon|wiki page about RDGpiMon]] for information about it.<br /> <br /> == Other useful Wiki pages ==<br /> <br /> [[GPIO.txt_-_GPIO_Notes_for_Rivendell]]<br /> </div>
