On this LPC2104, I am writing a 1K block of Flash in IAP. I have measured the prog time now, and it is taking 400mSec. That is longer than I expected. This is all I do: Prepare Sector Erase Sector (8K) Prepare Sector CopyRAMtoFlash (1K) Should this be taking 400mSec? Is there anyway to speed this up? Any shortcuts?

I want to be able to update our LPC2104 firmware with a UART interface. It seems like the UART is setup to rely on INTs for transfer. Given that the code must be executed in RAM, I suppose the INTs for the UART must be setup in RAM as well. Are there any example files around of this kind of RAM code setup for moving the INTs into RAM. I see it talked a

There were lots of discussions and attacking on the LPC2114-2294 and LPC213x/4x flash memory read protection. But had never seen the chip's protection proven could be bypassed so far. Could we jus
