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.
Regards,
Mark.
Mark,
Talk about timing. I am about to start using this same device. I was
going to use Linux and go that route. When I first started out I used
FlashMagic. I'm not sure yet about whether their ISP firmware support
for USB. But I will find out. I probably will be ordering devices today. I
found a good source for emulation sockets too. Other people I talked to
would have a minimum quantity of 10, but not my latest source. They
accepted an order for 1 socket.

Flash Magic doesn't know about anything other than RS232 communications.
Andy,
I suspected that Mark might be talking about the flash utility that
Philips provide, a program called "LPC210_ISP.exe". Although I
just looked at the data sheet for his device. They upped the baud
rate to 230k for serial ISP. But I see no mention for USB support.
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 ,
The LPC2148 and other LPC2000 32bit flash ARM7TDMI-S micros come with a default UART serail boot loader (not USB).
So either Philips would have to pre-load a USB boot loader - for default production OR a bootloader would have to be written and downloaded serially or via JTAG to each LPC2148 purchased.
Some LPC2000 designs have already written a Bootloader that can load / run your code from a flash mem card (interesting).
There is a good forum on the Philips LPC2000 series (including the LPC2148)
at http://groups.yahoo.com/group/lpc2000/
The Flashmagic programming interface is getting quite mature and supported by Philips..... Perhaps a version of Flashmagic can support the LPC2000 series with a little prompting from Philips in the future ;-).

Perhaps. ;)
Medic,
What does "HHC" stand for?
