I have connected a RS/232 driver to the X4-connector (X4-5/6, Y1) on the audiostix. I can get output from the audiostix by: -modprobe proc_gpio -echo AF1 out > /proc/gpio/GPIO48 But if I mess around with GPIO49 I also loose ethernet. Please note that I haven't tested if the CF-port dies when messing with GPIO48...guess it does... You mention one of the "newer" gumstix have possibility of enabling ttyS3 (HWUART) on GPIO42-45? How can I do that? :-) And where do I find the revision number of the gumstix? This is what is written on my gumstix: ---front--- GUMSTIX ?0.8 ---back--- 02V2 1305 94V-0 ^^I don't know if the revision can be derived from that ^^ If my gumstix is too old to utilize HWUART together with netCF, how do I enable STUART on the audiostix then? I've tried different stuff with GPIO46/47 and ttyS2 but to no avail. Hope somebody can help and thanks in advance :-) |

Is it possible to see the differences between the various hardware revisions? I've looked in the wiki and in the revision forum, but I don't see any clear revision numbers. Or can anybody tell me whether revision 0.8 supports HWUART on GPIO42-45 through the audiostix simultaneously with using a netCF board? If HWUART is not available can I then gain access to the STUART someway? All these questions ;-) Thanks! |

The changes on the 60-pin connector were in revision 0.9 -- so 0.8 doesn't bring out the GPIOs you're looking for. Your only option for a 2nd UART with #0.8 is the STUART if you're using an ether- or CF- board. > Or can anybody tell me whether revision 0.8 supports HWUART on > GPIO42-45 > through the audiostix simultaneously with using a netCF board? Nope, sorry, it doesn't. > If HWUART is not available can I then gain access to the STUART > someway? Not on the audiostix I'm afraid. The STUART signals don't come off the connector on that board. The revised audiostix though I think does have the STUART lines come out to somewhere you can connect to. > All these questions ;-) Hopefully enough answers :) > Thanks! np. C |
