Flash Installation

This process assumes that a Microsoft Windows machine with the Embedded Systems Academy Flash Magic utility is available.

The first step is to set up the board as described in the Embedded Artists documentation. The FlashMagic tool from http://www.flashmagictool.com must be installed to program applications or RedBoot into flash. Older versions of Windows may also require the FTDI USB driver from http://www.ftdichip.com/Drivers/VCP.htm be installed and configured as described in the Embedded Artists documentation.

Install the ISP jumpers (P2.10 and RESET) and press the reset button. The board is now running a special NXP boot loader. Start FlashMagic and set the Serial Port to the FTDI USB COMx device activated when the target hardware is connected to the host by a suitable USB cable. Select 38400 baud and change the device to LPC2468. Older versions of FlashMagic also require the Interface “None (ISP)” and 12MHz Oscillator Frequency - these settings are available under preferences in newer versions and are set correctly by default.

Test communication with the board by using the “ISP->Read Device Signature” menu entry. If communication is not successful, check that the correct USB cable is used and connected, the ISP jumpers are installed and the correct COM port is being used.

Check “Erase blocks used by Hex File” under “Erase” OR in recent versions of FlashMagic select “Sectors used by File” next to “Erase”. In the “File” section, select the redboot_ROM.hex file. Under “Options”, all boxes should be clear except “Verify after programming”. Now press the “Start” button. The utility should show the progress of the flash erase and write operations.

When the process completes, the utility should be closed. Verify the programming has been successful by starting a terminal emulation application such as HyperTerminal or minicom on the host PC and set the serial communication parameters to 38400 baud, 8 data bits, no parity, 1 stop bit (8N1) and no flow control (handshaking). Remove the ISP jumpers. Reset the board and RedBoot should start. The output should be similar to the following:

It is now necessary to initialize the flash file system and the flash configuration. This can be done with the following commands:

RedBoot> fis init
About to initialize [format] FLASH image system - continue (y/n)? y
*** Initialize FLASH Image System
... Erase from 0x803f0000-0x803fffff: .

RedBoot>

Replace the IP addresses in the above with those for your own network. The above also accepts the default for the MAC address, if more than one LPC2468 is to be used on the same network then different MAC addresses should be used; Embedded Artists boards are supplied with a sticker showing an assigned MAC address, and this should be used by preference.

It is it ever necessary to reinstall RedBoot, the above directions can be repeated. Alternatively, a new RedBoot may be installed from RedBoot itself. It is not possible to do this directly, since RedBoot is executing from the flash that needs to be erased and reprogrammed. Instead it is necessary to run a RAM version of RedBoot, use that to download the new ROM RedBoot to RAM, and then program that to flash.

The following shows an example session to do this. It assumes that redboot_RAM.srec and redboot_ROM.bin are available via TFTP on the server set up in fconfig.

RedBoot> load redboot_RAM.srec
Using default protocol (TFTP)
