Ah, so you're running a completely different firmware image? Well in that case that would explain the different response for the firmware loaded indication. > Not a 0x1388.

These are not parts that have any form of default firmware in their ROM mask (i.e. not like the silabs or micronas parts which have a default firmware and the ability to patch the ROM via a software loaded code update). The firmware must be loaded every time the chip is brought out of reset or it won't work at all. Devin -- Devin J.
