Hi, I'm not sure who maintains the getting started wiki, but I happened to be browsing and on this page: http://gumstix.org/compile-code-on-my-gumstix.html It downloads the source code for gpio-event, when I believe it means to download the source code for gpio. It talks about toggling an LED, which can't be done with gpio-event. Yes, I know it says: "Note: this article is not yet finished and requires additional content. Thanks for your patience and check back soon." The correct URLs would be: http://svn.hylands.org/linux/gpio/module/user-gpio-drv.c http://svn.hylands.org/linux/gpio/module/user-gpio-drv.h The example is also incomplete (I'd be happy to provide some more text). You also need to compile the user-mode library and user-mode app in order to be able to use it. -- Dave Hylands Shuswap, BC, Canada http://www.davehylands.com |

Can't anyone edit the wiki?

As far as I can tell, anyone can edit the "Gumstix User Wiki", but not pages like the one I linked to. At least I couldn't find a login/edit anywhere. -- Dave Hylands Shuswap, BC, Canada http://www.davehylands.com |

Hi Dave, Good catch and my apologies for the inaccuracies.

If you have appropriate text, I'll happily test the steps and correct this page. Thanks, Ash |

Hi Ash, sure - it may take me a little while to get everything together, but I'll work on it. Just out of curiosity, you mentioned that you were going to toggle an LED. Is there an LED on the over board that can be toggled via GPIO, or does it have to be an LED on a daughtercard?

None of the LEDs on the COM are directly controlled by GPIOs. Specifically, D1(blue) is controlled by the wifi module (where applicable), D2 (green) is a power indicator, and D3 (blue) controlled by the PMIC (thus, it is controllable but not directly by an OMAP GPIO). Customarily, GPIO21 and GPIO22 are hooked up to red and blue leds on expansion boards. Note on kernels > 2.6.36, these lines are reserved by the gpio-leds kernel module so you can't directly toggle 'em using sysfs (as I tried to do a couple days ago!) without unloading the module. -Ash |

Ahhh. One of the advantages of the gpio program/driver is that it isn't beholden to such restrictions :) -- Dave Hylands Shuswap, BC, Canada http://www.davehylands.com |
