WM8753 Speaker Playback ZC Switch
Hi All,
I am happily hacking on my FR and was toying with the wolfson.
I happen to notice that in order to get any sound from the earpiece i
had to switch on the Speaker Playback ZC Switch.
That switch is mentioned in the statefile, but i can't find it in any of
the diagrams on [1] [2]
Is there someone with an updated version of the diagrams, that includes
the two switches below?
control.9 {
comment.access 'read write'
comment.type BOOLEAN
comment.count 2
iface MIXER
name 'Headphone Playback ZC Switch'
value.0 false
value.1 false
}
control.10 {
comment.access 'read write'
comment.type BOOLEAN
comment.count 2
iface MIXER
name 'Speaker Playback ZC Switch'
value.0 true
value.1 true
}
Kind regards,
Ed

The one in the wiki is just an annotation of the Wolfson diagram, adding alsa
control numbers to the visible elements where I could identify them. I think
there were some elements I couldn't identify a control number for, and there
are a lot of controls that have no representative element in the diagram,
usually because they involve digital processing rather than an identifiable
analogue element. If you find a mistake or something to add then please make
the correction.

I happen to notice that in order to get any sound from the earpiece i had to switch on the Speaker Playback ZC Switch. This is used to enable/disable Zero Cross detection, i.e. the gain will be changed only on zero cross (or timeout). I'm afraid you'll need to refer to the actual datasheet to understand this in details. Feel free to ask me if anything is unclear.

Re: [GTA04] When is the next and more powerful openmoko releasing
Hi all, time for another update. Am 06.11.2010 um 12:35 schrieb Sylvain Paré: Thanks for the news Yesterday I received the second board where we did populate the TPS65950 (power controller). The results of measurements are: * the 32 kHz RTC clock is operating * when inserting a battery, most voltages are available as expected Bad news: * we have a short circuit on the 1V8 rail I have spent most of the night and this morning to track this down. It appears to be a solder short circuit under the TPS chip (a 0.4 mm pitch BGA). So I am currently sitting at our SMD rework company and looking over the shoulder of the CTO who has a lot of experience. Unfortunately I can't make photos. We already have unsoldered the TPS chip (that needs a really sophisticated machine) and the short has disappeared. The next step is to solder it back again and do the next tests. If that works, i.e. we get all voltages from the power controller, the 26 MHz oscillator should also start working. If that is ok, the OMAP and the POP memory will be soldered. Maybe we manage to get it today. Then, we can see if the CPU is doing something. Current status: the 1.8V is now working but the VDD2 (1.2 V) not. The TPS chip aborts the power up sequence early. We could solve that by adding a jump start resistor. Rene will upload some photos of the board and we will post a link. Here: http://download.goldelico.com/gta04/images/DSC00671.jpg http://download.goldelico.com/gta04/images/DSC00672.jpg Then, we soldered the OMAP3530 and Pop Memory chip and connected RS232: http://download.goldelico.com/gta04/images/DSC00679.jpg It did identify itself as 40W on the RS232 but did not boot beyond that. Fortunately the OMAP has a ROM bootloader (which generates the 40W sequence) and we could use it to download a special second stage boot-loader that has a simple commandline console on RS232. Note that it must fit into 64k SRAM built into the OMAP chip. So we are back to C64 times :) With this tool, we could identify that the (external) SDRAM has a stuck-at-1 error on a single bit-line. So we expected another soldering issue and had the OMAP+Pop replaced on Monday. But the error pattern remained the same! Unexpectedly, we were able to put the board into a 3D X-Ray machine on Tuesday (during Electronica Fair). Here are machine results: http://www.yxlon.com/y.Cheetah http://download.goldelico.com/gta04/images/2009%20Xray/ Fortunately it is *not* a soldering issue. And likely not a PCB production issue. Yesterday late at night we found the problem. It is a bad BGA ball assignment in our component library. VDDS_MEM (1.8V) is assigned to B17 instead of B18. And, B17 is data line 14 of the SDRAM and should have been left NC. Therefore we have tied one data line to a high-level... I think we can fix that for our samples but it needs some time and we run out of components for the samples. Especially memory chips have quite a long lead time. For the series version this will be very easy to fix. Nikolaus ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
