Hello all, I'm attempting to store all of my __irq() functions in the internal RAM. I have created an IRAM2 section (for LPC2129) I have the code mapped to the IRAM2 section. But, I haven't seen a good example of how to get the code into RAM. On previous ARM projects, I would have copied the IRAM2 section into flash in the "Startup.s" code. I don't understand how to get the "IRAM2_START" and "IRAM2_END" addresses for the ROM and RAM. I'm assuming that these are available and could be used in the assembly startup code. Thanks, Al
