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.

Correct. 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.
