Hello everyone. My name is David and study engineering at Taranto, Italy. I’m studying the LPC-P2148 Olimex board. That is the question: how can I communicate lpc-p2148 (then enter in ISP mode!!!) with hyperterminal in Windows XP via an RS232? Help me. Thanks
I recommend that you use FlashMagic to communicate with your board instead. It specifically supports communications with the LPC2xxx MCUs:davidino84:

Hello Chris. FlashMagic put in the Eclipse and when I start FlashMagic says “Failed to Autobaud”. I wonder also how do I communicate lpc2148 with hyperterminal. I can not understand where I’m wrong.
Read all of the tips in the Flash Magic App Note 4 "What to do if ISP does not work":davidino84:

We intermittently get the “Failed to Autobaud” error on various board / USB port / COM port combinations. It often works on the second or third attempt so try, try and try again. Keeping the baud rate low (e.g. 9600) usually gives the best reliability.
Ok thanks but I have to make some changes on the board lpc-p2148? Thanks

I followed what was written but does not work. I have to do something on the board lpc-p2148???
Help thanks!
Did you ensure you had a way to short BSL to GND while resetting the PCB to put it in ISP mode?
Some UART converters will give you DTR and RTS that can be used by tools like flash magic to hold BSL low while resetting the PCB, but it did not work with my converter cable, so I came up with a small contaption (
) - I just hold the button pressed while I press the RESET button - it works just fine for me.
Anyway this is only needed if you reprogram your boot code.
I tested an LPC-P2148 board myself a couple of days ago. All you need to do is set both DIP switches to ON. FlashMagic can then both program the board and automatically reset the MCU to run your program when you run its terminal emulator (Tools > Terminal).davidino84:
