Yes, perhaps. Well, tried on my WL-700gE and it also works (the only change is SDA gpio pin). :) It use the same ricoh chip.

Well, looks like we need to make general purpose: i.e. allow to specify sda/scl as module parameters.

Btw, does 24h switch destroys current clock setting completely? Or just hour value?

Also, this driver should have automatic devfs registration...

That shouldn't be a problem to implement. I assume you can do this yourself ;).

The switch to 24h mode doesn't really destroy the setting. Depending on the current time, it just leads to invalid time values within the chip. And according to the data sheet: "Any carry from lower digits with the writing of non-existent time may cause the time counters to malfunction." In any case, I don't think it's worth optimizing this, as it is only relevant the very first time you load the module.

The driver uses misc_register(), which already does devfs registration.

BTW.: Did you need to make any adjustments to my code, or was it already correct?

Yes. :)

Ghm... Right. /dev/misc/rtc is available. I've added hwclock applet to busybox and it works fine.

It was correct.

Well, do we still need compatibility with original asus code? I mean reading/writing via /dev/rtc?

In my opinion, this isn't needed at all. The reason why I implemented it compatible to the original asus code was just the missing hwclock applet.

Hi all,

thanks for your great work!

The WL-700gE has a RTC? I have to update my HowTo.
Can anybody tell me if the new driver will work with an older oleg firmware?
I am not able to test it atm.

Unlikely, it use new features.

Finally, this driver would be available in the firmware. The name was changed to gpiortc to honor existing rtc.c.

Anyway, clock synchronization will now be done automagically during the boot. RTC would be synced back at shutdown/reboot. No need in scripts, etc.

andi, thank you for your work.

I shouldn't have called this simply rtc.c at all, as the name wrongly implies some generic rtc stuff. I'd recommend rtc-rv5c386a.c which fits the current naming scheme of rtc drivers in the linux kernel.

Hi all,

i just want to report i finally updated to the new oleg firm, changed the driver and everything is working like a charm :-))))

Thanks so much to oleg and andi!!!

It appears this driver hasn't made it upstream yet. Is it available somewhere other than in Oleg's own sources? E.g. is it available for OpenWRT somewhere?

The OpenWRT wiki page for the WL-HDD still exists. The code there is for WhiteRussian. There's also some source code for Kamikaze, see ticket #1873.

Note that it only supports the WL-HDD, not the WL-700gE as Oleg's software does.

Thank you. I've adapted the package for Kamikaze so it now runs on my WL-700gE with 2.6.25.20 (and even automatically adapts to either one of wl-hdd and wl-700ge).

Code:

Hi there,

I'm also trying to get a solution to have a Real Time Clock on my WL500g, which does not have the required hardware unfortunately. However, I have a Dreambox (linux based satellite receiver), which has an RTC built in itself. I was thinking if it's possible, that my WL500g router connects to the dreambox and reads the time out from it.

I use my WL500g in client mode and I would like to set up a timeframe for "uptime" and "downtime"

Thanks for the help in advance!

I don't think this would enter the scope of what is usually considered "RTC".
You can use any kind of network-time tool, like NTP, rdate, ...

Hi,

This is exactly what I was looking for! Thanks a lot!

For the ones who are seeking for a similar solution, heres a little help from openwrt:
