We've used FlashMagic on the LPC17xx in the past. These devices have on chip ROM. We now have an LPC1830 system with off chip SPIFI ROM. I see the the LPC1850 is in the supported list. It has on chip ROM. Is there any way to use FlashMagic with off chip ROM on a device like this? I assume I will have to build code in to my image, and I don't expect it to work until the device is initially programmed with appropriate code. But is it reasonable to make FlashMagic work in this sort of system? If not, I'll be writing something from scratch.
