G400D

Overview

The G400D System on Module (SoM) is a 400 MHz ARM9. It is made just for running .NET Micro Framework.

Tip

Not recommended for new designs, consider SITCore System on Chip.

Development Options

Development Options

The UCM development options can greatly simplify the process of building a product or prototype using the UC5550. Options include a development board and displays which can get you programming in minutes.

.NET Micro Framework (NETMF)

The NETMF software on G400 is mature and complete. For more information on NETMF you can go to the NETMF Introduction page. The NETMF Getting Started page covers NETMF from setup of the host computer to program deployment on both an emulator and target device.

Bootloader v1 is needed for G400 to work with NETMF. It is available in the NETMF SDK.

Loading Bootloader

Download the G400 bootloader file and load onto the dataflash using the Microchip (Atmel) SAM-BA tool and the following instructions.

To set the chip in SAM-BA mode, hold down the dedicated button on your board (SYS A on UCM Dev and Breakout boards) while the system powers up (or during reset). If there is no such button, connect G400D pin SPI1_MISO to ground. Keep the button pressed (pin grounded) for three seconds after power up or reset, then release the pin. The device manager will show a COM port similar to "Bossa Program Port" or "GPS Detect".

  1. If it is not already installed, download and install the SAM-BA tool from Microchip. The latest version we have tested is 2.18 for Windows. (The tool may not show correctly. Try to make the window larger to see all hidden buttons!)
  2. Open the SAM-BA program then select the COM port for your device in the connection box and your board type below it (at91sam9x35-ek for G400), then click connect.
  3. Near the middle of the window, go to the DataFlash AT45DB/DCB tab.
  4. Under Scripts, select Enable Dataflash (SPI0 CS0) then click the Execute button.
  5. Under Scripts, select Erase All then click Execute. This will take some time to complete. It seems that if SAM-BA loses focus during the erase procedure it can seem to lock up. We recommend that once you click the Execute button you leave the computer alone until the erase procedure is completed.
  6. Under Scripts, select Send Boot File, click execute, then browse to and select the bootloader for the device.
  7. Once the transfer finishes, go to File > Quit and then reset the board. Make sure to properly quit the program or connection errors may result on subsequent uses.
  8. Now reset the board. Congratulations, your board is now running the loaded program!

Loading the Firmware

  1. Activate the bootloader, hold the LDR0 signal (SYS B) low while resetting the board.
  2. Open the FEZ Config tool and follow the instructions.

You can also update the firmware manually. Download the firmware and learn how to use the GHI Electronics Bootloader manually.

Start Coding

Now that you have installed the bootloader and firmware, you can setup your host computer and start programming. Go to the NETMF Getting Started page for instructions.

Datasheet

This documentation page replaced the legacy datasheet PDF but it is here for reference.

G400D Pinout

Many signals on the G400D are multiplexed to offer multiple functions on a single pin. Developers can decide on the pin functionality to be used through the provided libraries. Any pin with no name, function, or note must be left unconnected.
