There was a problem with an earlier version of the P3 bootloader which is
the likely cause of this error.
Due to some inaccurate information in the datasheet, a control bit for the
CPU is set wrongly, which prevents the bootloader from writing to the very
top of the internal flash memory.
With a firmware image over a certain size, the last few blocks will not
write, and you get a checksum error.
The P3 may still boot and run, but if it attempts to access any of the data
stored in the unwritten blocks, weird things may happen.

Download and run the bootloader update from Yahoo files.
The sysex file is here:

There are instructions in:
