I’d just bought the ARM7 LPC2478STK development board from Sparkfun. When I was first power in this board it appear Linux (penguin logo) and a few text say that "U-Boot 1.3.2 (Oct 7 2008 - 07:02:24) " but nothing was sent through the RS232 interface of the board(I use RS232 cable to connect this board to my PC), and nothing(no any text and no any logo) appear in my terminal program too.Is it have a problem or not???
Another thing is that I had a problem when I use Flash magic tool to communicate with this board.When I try to flash the hex file to the board it appear and error “Operation Failed. (failed to autobaud - step 1)”. What is the cause of this problem and I want to know how can I resolve this problem.

Thank you very much

Hi, first you have to set up correctly your hyperterminal (look at your board datasheet) generally 115200 bps, 8N1 works.
then reset your board and you should see the U-bool loading.
when you use the flash magic you have to setup your board to suport SPI and external reset. you may have to jumpers for this purpose. you have to setup both jumpers before you can use the flashmagic tool.
last thing to do is to config the flashmagic tool to use the DTR and RTS.
