09:19.40ao2hi p3t3r__ I found out that with 2.6.21 kernel the usblan thing works on A910. Even if mmc is still dead. Still no luck with 2.6.24.
09:20.12p3t3r__ok, nice.
09:20.31p3t3r__but strange that it doesn´t work with 2.6.24
09:20.56p3t3r__(i don´t understand much about kernel stuff.......)
09:21.47p3t3r__(i needed a long time that USBLAN on Ubuntu 7.10 didn´t work because of "zaurus" module misssing ;) )
09:22.45ao2some update in mailine linux could have caused the problem, or, more likely, a bad port from me.
09:23.22ao2I have to find a way to see the whole backtrace, maybe a serial console if I manage to find the right testpads on the PCB

19:22.46ao2hi, how to check if these testpads on the right provide UART? http://people.openezx.org/ao2/pictures/a910/00004.jpg solder and test with a max232 interface? Can I supply power to the max232 from a usb port from PC?
19:23.57ao2btw, A910 have also what looks like a pigtail connector, so maybe we could also connect an external antenna for wifi http://people.openezx.org/ao2/pictures/a910/00006.jpg
19:26.13LuitvDyou should be able to power a max232 from USB... it only uses 10mA
19:27.07ao2what about voltage? are 5V fine?
19:27.29LuitvD5V is the only right voltage for the MAX232
19:27.39LuitvDI don't know what those test pads do though...
19:27.55ao2well, actually my interface is built around a MAX3232CPE
19:28.48LuitvDhmm, that does make a difference
19:29.46LuitvDthat one only uses 300µA :O
19:30.23LuitvDI guess you should power it from the battery
19:30.27LuitvDno wait...
19:30.34LuitvDfrom the power regulator on the phone
19:30.55LuitvDor a good lab supply capable of delivering 3.3V
19:31.12ao2so I have to find that line on the phone first
19:31.26LuitvDperhaps
19:33.56LuitvDyou should check the signal with a scope first, IMHO
19:34.49ao2what if I wanted to build a converter from the USB power line to suppy the values needed by the MAX3232 ?
19:35.07ao2I only have a multimeter...
19:35.23LuitvDyou'd need a power regulator to get 3.3V
19:36.05ao2ok, now I know it is called "a power regulator" :P
19:36.38LuitvDwith that multimeter: switch to AC mode, put the negative lead on the testpad on the groundplane, and the positive on one of the pads while trying to send some data over UART
19:36.47LuitvDsee if it reads something
19:37.35LuitvDor can't you switch the phone on while it's taken apart like this?
19:38.13ao2not really
19:38.23LuitvDhmm
19:39.22ao2ok, see you later, thanks LuitvD
19:39.27LuitvDyou should get some thin wires soldered to those pads :P
19:39.33LuitvDbye ao2

21:55.37ao2hi stefan_schmidt
21:55.59stefan_schmidthi ao2
21:56.14ao2stefan_schmidt, do you know if the serial console via USB is still possible with 2nd gen ezx phones?
21:56.38stefan_schmidtao2: No idea. I only tested it with the 1st gen phones
21:56.58stefan_schmidtao2: Never had a look at the EOC code
21:57.54ao2ok, thanks. Because I have a oops with usblan on 2.6.24 on A910. While usblan works with 2.6.21
21:58.33stefan_schmidtao2: hmm, checked for a newer pxa_udc patch?
21:58.57stefan_schmidtao2: Could be that something changed upstream and there is already a new patch from RP
21:59.03ao2still no luck regarding mmc controller. The driver used on A910 is different from the one used on other phones, because of the SDIO stuff, so maybe some initialization is a bit different.
21:59.30ao2stefan_schmidt, the one we are using is from Rodolfo Giometti, and no updates from him
22:00.15ao2the one from RP provides ethernet gadget?
22:00.49ao2(I hope my english teacher is not on #openezx...)
22:01.01LuitvD:P
22:02.00stefan_schmidtao2: hmm, not sure about the latest and greatest in pxa_udc land. I just now that there are floating around various patches which all need work for mainline inclusion
22:02.17AndiMstill stuck with amplifier stuff
22:02.20stefan_schmidtAt least everytime they appear on l-a-k long discussions start
22:02.51stefan_schmidtAndiM: yeah, the fun off low level stuff. It can take ages to get anywhere. :)
22:03.32AndiMI really don't know any more which kind of driver interface I'm supposed to implement or not...
22:03.45AndiMpure versionitis...
22:03.46*** join/#openezx tombhadAC (n=tombhad@pD95DD425.dip.t-dialin.net)
22:16.33ao2AndiM, can this be useful to you http://www.rpsys.net/openzaurus/patches/mmcsd_no_scr_check-r2.patch ?
22:16.39stefan_schmidtao2: ah, a lot more detailed photos
22:17.36ao2yes, I was looking for some testpads for a serial console, maybe the three in that corner... don't know yet
22:18.17stefan_schmidtao2: I was also surprised to find none on the first glance
22:18.36AndiMao2: NOT AT ALL. It *is* a bug, using a dumb workaround is not an option.
22:18.49AndiMao2: (but thanks for pointing to it)
22:18.52stefan_schmidtao2: On the RAZVR2 V8 there are also no obvious onces. Perhaps integrated in the display connector...
22:19.00LuitvDao2: what happened to that front-panel LCD display?
22:19.30stefan_schmidtLuitvD: That was already broken before p3t3r donated it
22:19.38LuitvDah, shame
22:19.40AndiMdoes anyone know why I keep getting i2c_pxa_wait_bus_not_busy errors whenever I manage to do at least *something* useful with my driver?
22:19.58stefan_schmidtLuitvD: Not really. It was the _reason_ he donated it. :)
22:20.07LuitvD:P
22:22.41LuitvDwhere do they even sell these phones
22:22.45LuitvDcan't find any :P
22:23.22stefan_schmidtLuitvD: GB and FR
22:23.31LuitvDreally
22:23.36LuitvDhow expensive are they?
22:24.02stefan_schmidtLuitvD: Cheap, you should be able to get one on ebay for ~70Eur
22:24.15LuitvDoh nice
22:24.26stefan_schmidtNo touchscreen though
22:24.33stefan_schmidtMore like the ROKR E2
22:24.53stefan_schmidtOnly the wifi is interesting :)
22:25.10LuitvDcan't find any on eBay :P
22:25.23stefan_schmidtLuitvD: Not only .nl search...
22:25.43stefan_schmidtOr there are just none atm
22:25.48LuitvDsearching internetionally
22:26.01LuitvDi guess they're all out atm
22:26.26stefan_schmidtok
22:26.49LuitvD90% of the hits are UK parts, and some DE, but no complete phones

22:47.20LuitvDhm, looks like Orange sells the A910 too...
22:47.39LuitvDwhat battery is used in the A910?
22:47.58stefan_schmidtBT60
22:49.53LuitvD1Ah right?
22:50.35stefan_schmidtNo idea
22:51.46LuitvDI guess it's 1000mAh, too bad it's a little different from my ROKR's batteries
22:51.51LuitvD(BC70)
22:52.41ao2BT60 3.7V
22:52.44LuitvDstill like to have a phone to use while I'm hacking my ROKR though...
22:53.18LuitvDeither a A910, or something using NXP's yet-to-be-released design
22:54.38LuitvDsomething not too expensive, and more fun then my first mobile phone :P
22:55.43LuitvDao2: nice toothpick by the way ;)
22:56.10ao2from the SAK
22:56.17LuitvDI know :)
22:56.53LuitvDwhere did you get the torx screwdriver?
22:57.12LuitvDjust bought one?
22:57.41LuitvDgonne buy one too I guess... take this ROKR apart
