Hello list, I'd like to start using net5501 as a base for the devices produced by our company. Before doing this I want to make sure that GPIOs work properly with Linux. I found that many people report success working with net4501/4801 GPIOs. But the net5501 uses different hardware - CS5536 chip. I could not find any information about using its GPIOs.
I have handy a different mainboard with the same CS5536 companion chip. I've installed Archlinux (2.6.28.1). The driver - cs5535_gpio is loaded and I can see the devices /dev/cs5355_gpioX. I can read GPIOs and get strings like "0IoabTPdnxL". I've looked into the driver's code to understand how to set I/O, Open drain etc. Trying to do something simple, like changing from "input" to "output" with e.g. "1iOabtpdnxH" has no effect (the subsequent reading as well as direct measurement show no difference). Could somebody give me a direction? Thanks, Sergey _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
