> Dear all,
>
> the JetDroid project has made some good progress in the past. In order to
> ensure we can continue at this pace and make good progress in the future I
> am now asking you for help. What is needed is some missing information about
> the Jet hardware. Knowledge of this is essential for further development and
> driver support for all parts of the phone hardware. Without this information
> support for some parts of the hardware cannot be developed (at a reasonable
> effort)
>
> How can you help?
> If you know someone who has access to Samsung schematic diagrams please ask
> if you can get the missing information or take a photo of parts of the
> schematics. I know that it is most probably impossible to get a copy (e.g.
> PDF) of the schematics, thus I am just asking for some information. So, if
> you best friend is working in a phone repair shop and he or she as access to
> this kind of information, please ask this person.
>
> What is needed?
> To fully understand the phone hardware we need to know to which port e.g. of
> the main phone processor the peripheral chips (e.g. WLAN, bluetooth, modem,
> sensors, etc.) connect to. All pins/ports of the processor have names and we
> know them. What we need to know is to which signal (names) these pins
> connect to. In some cases the connection to the main processor (S3C6410) is
> known but it is not known where the other end is connected to.
>
> How to provide this information?
> Below I have compiled 4 lists. List A lists pin names of the phones main
> processor S3C6410 (in the schematic diagrams it is referenced as UPC701). If
> you can help please provide connections like e.g. XM0ADDR12 -> LCD_SCLK
> (which means pin XM0ADDR12 connects to signal LCD_SCLK). Completing this
> list is of highest performance
> List B list signals of which the name is known but it is not known where on
> UPC701 they connect to. Please provide connection information like for pin
> A. All signals on this list should connect (at least) to one pin from list A
> List C lists signals of which the name is know as well as the connection to
> UPC701. For these signals the other end of the connection is needed. Please
> specify connects like BT_HOST_WAKE -> U201 (BT_GPIO_1) which means signal
> BT_HOST_WAKE connects to pin BT_GPIO_1 of U201. For this list only
> connections to components other than UPC701 are needed.
> List D lists signals of which the name is know but it is not know where they
> connects. For these signals information like for list C are need but the do
> not necessarily connect to the main processor UPC701
>
> Too complicated?
> If you have access to the required information but don't know how to read
> the schematic diagrams, please search for as many of the names below and
> shoot photos for the different sections of the schematic diagram and mail
> them to me.
>
> I hope you can help to resolve the missing connections.
