Infinity touch

SOC used is a SuperH (SH2A) architecture 7267 running at 144Mhz http://www.renesas.com/products/mpumcu/superh/sh7260/sh7266/device/R5S72670W144FP.jsp

WiFi module is a MICROCHIP - MRF24WB0MA (datasheet)

The back side of the board contains a 16Mbyte FLASH in a TSOP package. (datasheet)

U10 on the back (screen side) of the board appears to be a MAX485 IC (a better photo would be nice) and is surrounded by the expected resistor bridges and capacitors for that circuit block.

It appears to handle encryption on board and have a SPI bus interface, so as a last resort sniffing the SPI traffic could work. Fortunately that hasn't proved necessary.

It has a 14 pin H-UDI debug connector as well as at least one debug (ttl?) serial port broken out.

The serial port appears to be unconnected. Power cycled with logic probes attached to soldered headers shows that the RX pin goes lower after boot, but the TX pin appears to be NC.

All control apps seem to be based on Adobe AIR. Does it run Linux? Can it be rooted? Can the USB port be used for anything other than loading background images? Any ideas or knowledge welcome.
