I know that FlashMagic only works over serial comms.

Apparrently HCC are on the verge of releasing a USB boot loader for the LPC2148 chip so it can be done.

Just thought someone might have tried writing a small code stub that uses the IAP functionality to pass updates from USB into the LPC flash.

Thanks anyway.

Hi Guys,

Anyone know of any sources of information on having some code that can reflash LPC2148 using USB?

I figure some USB code sits in flash and acts as a gateway for firmware updates. Thought I'd ask before recreating the wheel.

Hi Andrew,

Thanks for your reply.

I'll just have to get the MCB900 (yet another dev board)!!

Hi All,

Have been reading all the discussion and app notes with interest.

I'm interested in using the P89LPC901 device and am amazed at how complicated it appears to program these devices??!!

As I understand it the simpliest/cheapest method would be to buy an MCB900 dev board and a PAB90x-1 programming adapter and use FlashMagic to do ISP over an ISP to ICP bridge, is that right?

Why is anything other than an RS232 chip needed to interface FlashMagic to the device? I could supply power and toggle reset independantley to get the device into reset mode and then just use serial comms to program the device? I looked at Maurits van de Lande schematic and that appears to be a automatic implementation of this?

I am already using the full version of Keil C51 and have other dev boards so dont really want to spend more money on another development board just for programming.

All I want to do is program the 901 either before or after soldering into the target hardware without having to invest in extra equipment.

I'd really appreciate your experiences on this as it's perfect for my app but might not be worth the hassle if so much effort is required to program it...

Many thanks,

Mark.
