Hi everybody,

Would greatly appreciate any help with:

Trying to program the HCS12A64 device using a serial link. I have read through many of the apps notes but there does not seem to be a straight forward method.

In the application we have access to the serial link on the micro. I can issue a command trough hyperterminal which will start a bootstrap loader. I would like the bootstrap loader to then take a S19 downloaded file and overwrite the original application.

There must be a bootstrap loader in existance which can do this.

Anyone got any suggestions?
