Remove the get debounce clockfailure message as it is noisy for other platforms.This would be good to get in during the -rc cycle if possible to removethe bogus warnings on non-2430 weblink

If you ls -l /dev/mmcblk* for both cases you notice sometimes /dev/mmcblk0 has correct minor number 0 and sometimes it has 8 which according to kernel naming belongs to mmcblk1 device.

Instead of fixing it in kernel (in few lines) so both kernel and userspace have the same view of mmcblkx devices, we made a half working fix in userspace (udev rules?)

Linville Someday the world will need a hero, and you [email protected] might be all we have. Personally, I just poll (maybe 100Hz or so) and when I get some number in a row that are the same logic state, I call it good and be done with Jim Jim Wagner Oregon Research Electronics, Consulting Div.

This extends couple of in-kernel structures in addition to mmc modules so it needs also new matching kernel. We want to enable the debounce clock only for OMAP2430, Right? When I increase the capacitor size to 0.33uf the bouncing I see on the logic analyzer channel increases in length, not much though. Comment 2 Frantisek Dufka (reporter) 2008-02-19 15:15:29 UTC Looks like this is by design, see comment http://lxr.linux.no/linux+v2.6.21/drivers/mmc/mmc_block.c#L470 ...

I guess, if our application calls for some more robust solution, than this simple delay thing wouldn't be appropriate.

You have to decide what works for you.

I don't have the numbers handy, so the following numbers are rough: It cost something like 20 clocks every 10 ms - that's 2K clocks per second, or a processor load

There is also a small amount of capacitance and inductance. I assume that documenting this would be welcome? L datasheet has a chart, indicating about 0.5V of hysteresis at 5V Vcc. (cannot paste from the locked datasheet). check over here The other boards are there for the micro and other assorted chips.

Instead, I am still left with no virtio-net backend implemented, and you were left designing, writing, and testing facilities that I've already completed. The current name change is a hack, > agree. And the "big" button probably wants to see a higher current on its contacts.

So do you guys think I am actually seeing something other than bouncing?

If you drive it wrongly then it is hard to investigate without understanding it. At least on my N900 when microSD is inserted at boot time it gets mmcblk0 and eMMC gets mmcblk1.

Please explain to me how you see this because I cannot. this content If the pin was made an output and set low, current will flow.

Everyone else swears by the Peter Dannegger debounce routine. Yikes. 5 watts? Sometimes, tighter tolerances may be needed. Sep 4, 2002 Posts: 26616 View posts Location: Orlando Florida #52 Posted by bobgardner: Tue.
