I just switched to 2.6.39 for my overo and noticed that the device /dev/twl4030-madc is gone. Any clues to how I can get it back?

Thanks for your fast reply Steve. I am able to see /sys/class/hwmon but it is empty. Do not see hwmon1/device. I am using linux-omap3-2.6.39 from the overo-2011.03 branch with the provided defconfig.

No, all madc channels work in my image. I just verified this by downloading the script at: http://sakoman.com/category/8-gnome-daily-builds-r13.html# I used the downloaded script to create a console image and then tested each madc channel by connecting all of them to 1.8V.

I's sorry you are having trouble, but I don't think my image is the problem. Are you using the most recent version of the script downloaded from that page?

Hi Steve, Thanx for confirming that.

I have a sonar[1] connected to the ADCIN4 and AGND and I'm feeding it 2.4 volts. My voltage meter shows that it's giving proper values out but I don't see any changes in in4_input file.

I have the same issue, only inputs 2 and 7 work, input 3 try 6 always display "21" regardless of what I connect them to. My kernel is based on the current omap-3.0-pm head, f77d38b6ccbd9cb1e4e5fe92f7dd939b9f6f86d9 to be exact. The patch you mentioned that enables these inputs is indeed in the twl4030-madc.c file. I take it that the "no reply here" means that the original poster just gave up? In addition to your patch, I also added the platform_data to the board file as described above, otherwise the driver won't load. -- View this message in context: http://gumstix.8.n6.nabble.com/dev-twl4030-madc-gone-in-linux-omap3-2-6-39-tp590910p4964818.html Sent from the Gumstix mailing list archive at Nabble.com. |

I had to patch Steve's image to get those other lines to work, just FYI, but that was a little while back that I based my image on (Nov last year, maybe?) - I am sure the new head is fine. RE absolute maximum; you have to read the TPS65950 technical manual. If you apply more than 2.5V, from memory, all bets are off. While you may lose some resolution, leaving yourself some safety margin would be a good idea... One thing I haven't checked with my latest HW is whether ADCIN7 still floats around 1.4V. I had a suspicion that perhaps it wasn't muxed out properly (I don't remember which adcin lines on the tps can be reconfigured, but 7 sounds suspiciously familiar).
