I was wondering if you guys can use the G1's driver. I was doing some researc and found resemblance wit the processor/graphics chip it has (MSM7201 which is I think on the GSM versions of the TP2) and both are ARM9 architecture and allow te use of complex and extended propietary instructions and signals. The G1 features a extUSB port... and of course likely reports to the whole QSD thing to tell it's status and process sound.
Another phone is the HTC Droid Eris which also features the MSM7600 that is on te CDMA versions of the Touch Pro 2. Also features a extUSB thing. Is it possible to get the driver for audio off the Droid Eris or G1 and port it to the Touch Pro 2..... since they basically use the same processors (CPU/GPU/ and Multimedia-wise) (More notes below) and feature the extUSB..... it's basically porting the same thing over ......
I may be wrong though but it's just a suggestion since I thought that extUSB really has something to do with it.... maybe the developers just overlooked it or something (no offense).
I heard the MSM7200 and the MSM7201 have some key differences. 45nm nand shrink for MSM7201 and the oter one is technically just produced by Broadcom (older nand shrink techniques but same ARM9 architecture) and was seperated numerically for legal purposes. All in all they use the same ARM9 architecture. MSM7200 on TP2 and MSM7201 on G1.
MSM7600 in Droid Eris and Touch Pro 2 CDMA are exactly the same. Well from what I've researched that is
Thanks for all the developer's efforts to making Android on TP2 possible |
just because teh chipsets are the same doesnt mean shit is initialized or that I/O between the processors/coprocessor/sound chipset is the same. please read and re-read OP explanation.
furthermore. Sound is working on TP1 which has extusb and similar chipset so there goes that explanation.
so far they've come to the conclusion that the only way to know for sure. without making wild guesses would either be the hardware debugging (which someone on xda is doing) and/or decompiling the windows drivers
to see exactly how windows initializes the sound for use.
I highly doubt it's extusb though given all the other extusb winmo phones that work just fine with android and have sound.
