TS-4710 Booting up the board

From Technologic Systems Manuals
WARNING: Be sure to take appropriate Electrostatic Discharge (ESD) precautions. Disconnect the power source before moving, cabling, or performing any set up procedures. Inappropriate handling may cause damage to the board.

Using one of the "off the shelf" baseboards, be sure to refer to that baseboard's manual here. Different baseboards use different power connectors, voltage ranges, and may have different power requirements.

The macrocontroller only requires a 5V rail from the baseboard which may be regulated from other voltage ranges. Refer to the #TS-Socket Connector section for the POWER pins. While operating the board will typically idle at around 350mA@5V with the PXA166 or 450mA with the PXA168, but this can vary slightly based on your application. For example, every USB device can consume up to 500mA@5V. The ethernet interface can draw around 50mA while the interface is up. Every DIO pin can source up to 12mA from the FPGA. A Sandisk SD card can draw 65mA@3.3V during a write, and larger cards can consume more. A typical power supply for just the macrocontroller will allow around 1A, but a larger power supply may be needed depending on your peripherals.

Once you have applied power to the baseboard, look for console output. The next section of the manual provides information on getting the console connected. The first output is from the bootrom:

The "Booting From" message will indicate your boot media. The 2 dots after indicate steps of the booting procedure. The first dot means the MBR was copied into memory and executed. The next dot indicates that the MBR executed and the kernel/initramfs were copied into memory and executed.
