Hi,

I have successfully plugged the GPIOs_P9_P8 device and map GPIO_49 output(QX6.1) to a variable using the device editor. I created a program to blink the variable and when the program executed I could see the variable changing. However, the actual output did not change. I have tried all the update methods(Enabled 1, 2, parent device). Did I miss something?

Hi Edwin,

Thanks for the information. Now the output is working. But can you explain to me what the update option "Use parent device setting" and "Use parent bus cycle setting" mean? Who is the parent? Because when I use "Use parent device setting" the program crashes with an exception. "Use parent bus cycle setting" works but I don't know where this cycle time can be set.

Is there any document showing the steps to set up the program for Beaglebone? The only document I could find is the gettingstarted document, but the info are scarce. The step to configure the I/O like what you've shown me I couldn't find anywhere.

Thanks for the help!

Best Regards,
