OK, I have designed a cape, a Quad Stallmotor controller with/sense, which uses 8 GPIO lines: four as outputs to drive a "stallmotor" type of switch motor for model railroad turnouts [switch tracks] and four inputs to sense the current state of the stallmotor (the state of the switches).
The I/O pins I am using are: // GPIO0_7: P9-42 // GPIO1_6: P8-3 // GPIO1_28: P9-12 // GPIO1_7: P8-4 // GPIO1_16: P9-15 // GPIO1_17: P9-23 // GPIO3_21: P9-25 // GPIO3_19: P9-27 I am testing the cape and I having some issues and wanted to check if there are problems with using these pins, partitularly GPIO1_6 on P8-3 and GPIO1_7 on P8-4 and I am slightly confused about GPIO0_7 on P9-42 (P9-42 seems to be listed as P9-42a and P9-42b). I am getting kernel error messages relating to mmcblk1 (I am not using mmcblk1 and I have zeroed it). I *think* this might be because what is "wired" to P8-3 and P8-4. Should I be looking at redesigning my cape to use other GPIO lines? -- Robert Heller -- 978-544-6933 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services [email protected] -- Webhosting Services -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
