But no I didn't find it, seems I've looked at the wrong places. I gave up the "ROMRAM" target. I started writing flash drivers and using Redboot instead. Which I have now running (using a serial port) on our hardware. I load a "RAM" binary from FIS, which is a good replacement for "ROMRAM" (and more :-)). Pretty feature to be able to use the same code for debugging in RAM and for the production version loaded from flash. All the best Peter
