MayGion MIPS IPCam



The MayGion MIPS IPCam is a generic ethernet connected webcam.

Specifications



 * 360MHz MIPS processor (Ralink RT5350 SoC)
 * 4MB flash (MX25L3205D 32Mb SPI)
 * 27MB RAM
 * SoC provides one USB port, connected to an onboard USB hub (058f:6254), with these attached devices:
 * 0c45:6360 Webcam
 * 058f:6366 Multi-flash reader (with only SD card connector)
 * Hub and card reader are provided by Alcor Micro AU6350 single chip integrated USB2.0 hub and multimedia card reader controller
 * SoC provides 5-port ethernet switch:
 * One port is used for external LAN port
 * One port may be connected to the 802.11b/g/n wi-fi interface
 * Wolfson Microelectronics WM8988 Low Power CODEC with Headphone Driver provides speaker output and microphone input
 * ULN2803AG Octal High Voltage, High Current Darlington Transistor Array - presumably allowing GPIO control of the 5V PTZ motors
 * Fitipower FR9886D 23V, 2A, 380KHz Synchronous Step-Down DC/DC Converter

Serial console / bootloader access
There does not appear to be any way of accessing a serial port on the PCB, despite the kernel sending output to the SoC's serial port. see below

Serial port is available as shown in the photo -  [[Media:MaygUart.jpg| UART]] 57600 baud rate

The bootloader is U-Boot 1.1, and it appears to be set to boot over TFTP from 192.168.1.23 within five seconds after power on (according to the U-Boot environment variables in /dev/mtdblock1), although obviously this doesn't happen. The device does not emit any ARP queries or other network traffic until the Linux kernel has loaded.

A high resolution image of [[Media:Maygion.jpg|MayGion Board with solder mask removed]] is available. Data sheet reports TXD on P3 and RXD on N2.

JTAG is listed as A11 A12 A13 A14 B11   - JTAG_TRST_N JTAG_TCLK JTAG_TMS JTAG_TDI JTAG_TDO

Firmware
This firmware was pulled directly from the SPI EEPROM. It has not yet been verified, but appears to be complete. [[Media:MayGionMipsDump.zip|MayGion Mips Firmware]]

dmesg
This was obtained from the stock firmware by uploading a fully featured busybox binary and using it to run dmesg.
