The ZD and ZE have the same amount of SRAM, 64kB.  This is correct in
the config files.  The ZD has 384kB of internal flash, whereas the ZE
has 512kB.  I have changed the .ldi and .h files for the ROM startup
type to reflect 384kB.

hal_startup_stack was set to be at start of SRAM+64kB.  Reducing the
64kB number didn't seem to help anything, but I'm not sure if it
should have done.  I also tried reducing the interrupt stack size in
my configuration from 4kB down to 2kB, but this also failed to help.

I have just built Redboot-ROM from the same set of libraries and
flashed it to the board and it appears to consistently boot correctly,
suggesting that the board itself should be OK.

Any ideas would be appreciated, particularly evidence that
applications built in ROM mode work/don't work on other people's
boards.

Thanks
