Dear All,
In my System, I am using ARM7-LPC2478.I was updating the configurable parameters using IAP mode to write data in Internal Flash. I am having one more requirement. I have to update the firmware via USB in IAP mode. I am using Keil Micro Version3 IDE. How to Invoke the Hex file generated by Keil.
I gone through the Intel hex file format, and understood the hex file format.
I want to know difference between Data updation and Firmware updation using IAP. Whether Firmware updation requires UU-Encode.
Kindly provide some simple sample code to achieve the above mentioned requirement (Firmware Update using USB device in IAP)
Thanks & Regards, E.SundarRajan +91-8904468284

I've seen a HID bootloader elsewhere, but I can't remember it. You'll see many variety of USB bootloader for LPC2148 on the net. The USB device engine and IAP is (almost) common throughout LPC2000 families You may apply bootloader for LPC2148 to LPC2478 just with minor change.
