SX1 hardware
-
You can find full SX1 schematic on the net, here is the small list of SX1 internals:
-
CPU -
![[WWW]](/moin/handhelds/img/moin-www.png)
TI OMAP310
-
SDRAM - Samsung K4S28163LD (16MB mobile SDRAM)
-
FLASH - there are two types of SX1, I call them "old" and "new":
-
LCD - 176x220 NEC display, with some kind of Epson-like controller on it.
-
Sofia - OMAP power control IC, it supplies power for OMAP, LCD, LCD backlight and keylight,
-
Egold - it is Infineon PMB7850 processor, based on Siemens C166 core, handles GSM modem functions,
-
Bluetooth - Infineon PMB8760. Connected to ttyS0 (UART1) on OMAP and PCM interface is connected to DAI interface of Egold. Seems to be supported by BlueZ (http://www.bluez.org/)
-
Irda - connected to ttyS3. LED power is controlled via GPIO1 (A_IRDA_OFF)

-
MMC slot, Bluetooth, SDRAM, FLASH. It is controlled with I2C bus.

this part seems to be based on Siemens S55 hardware and (maybe) software, connected to OMAP via serial port - ttyS1 (UART2) on OMAP side.

As I have only "new" variant of SX1, so here I assume you have such SX1 too.
