Hello everybody, Is there a Bootloader wich load the firmware from a flash card (MMC or SD)? I use uVision3 for programming an LPC2148. I just found App Notes but no Examples.
Could anyone help me?

What you need to do is: * Understand IAP (in application programming). * USB basics (especially MSD). * Read the code. It really is not too hard. * Implement a SD card interface - that is complex, and RL-ARM (assuming you have a license) is rather ROM heavy.
Why do you need the SD card? isn't a RAM image provided via the MSD enough?
The Project Idea is to build a small, portable Datalogger, which firmware can easily be updated by MMC/SD-Card. Simultaneously, this Card is needed as storage for the logged Data. This Data you can view on your workstation. The case is that you can't always take out the Datalogger (For Ex. into a model aircraft).

I should have posted:
Why do you need the SD card in the bootloader? Why not use the MSD for firmware update and use the SD card in application?
I'd like to update my Datalogger "in the field", without using a workstation for updating. It's just more comfortable. And I don't need an USB-Port on the Datalogger which have to be very small. That's the reason why I need it.
The bottom line: you want a "turn-key" solution. It is rarely that simple!
Or, if it is that simple, it will not be free - not by a long way!
