iriver h1x0 - RTC (real time clock) mod
Peter200lx:
Well, I've installed the chip (Without the alarm mod for now) and have a patched version of rockbox, but it's still not showing time anywhere. I applied the rtc_with_alarm.patch . I even have gone to /General Settings/System , but there is no set time option. I am using rockbox with flashed firmware, could that be the problem? If you have any ideas, please tell me.
--EDIT--
ACK I didn't notice that I needed to uncomment those two lines, clock is working, and as soon as I sodder the alarm button on, I can test that! Thanks A Lot!!!

Glad to hear it worked!

Well, did some further testing and the clock is working great, tested the clock plugin and scrobbler and such, working great. The one caveat is that the alarm isn't working in any way. Right now I just have that wire going nowhere. Whenever I hook it up it starts the last song and play/pauses it forever. I have a patched firmware with both of those two lines uncommented, so I thought that it took care of that. Any ideas?

Rockbox with the the alarm mod patched and enabled should disable the alarm pin on start-up. So you can check that you have the menu entry "wake-up alarm" under General Settings/System.
Also you might want to double check that you haven't accidentally shortened the SQW/INT pin with another one (i.e. the SCL) when soldering on the wire.
That is all I can think of at the moment.

I finally had success with the mod!
However, it was a sobering experience. My first attempt resulted in an H120 that would not power on. Resetting the H120 did not work. I thought I bricked it. I disconnected the mod and still it would not power on even with a reset. But about a half hour later I tried plugging it into a charger and it powered on!
BTW, I followed the suggestion about using mouse wires. I found an old serial connected mouse and cut up the cable to obtain the thin flexible wires inside.
I decided that since my first attempt did not permanently brick it that I could try again. This time I looked for another Vbackup source other than the power connector on the other side of the mainboard. I found a source that was the same voltage as the battery. The bottom right of the mainboard (oriented with the headphone jack on top) has two square solder coated objects. The rightmost of the two has a 4.1 volt reading, so I decided to use that solder point. It saves unscrewing the mainboard and flexing more leads and routing the Vbackup wire around the board.
This time I tried to be very careful of where the dangling unsoldered wires wandered about the board. Everything went fine and the clock plugin started working. It did not work without the RTC chip installed.
BTW, I like the date-time naming of the recorded filenames. That avoids problems with editing the file contents and changing the date-time modified value.
Overall, using the flexible mouse wires and using the new Vbackup source made the project relatively easy.
