Hello Everydoy!

I've got a DEMO JM Board wich I was using withou problem till just a few seconds ago. Now I can't download the code to the MCU. The MCU is MCF51JM128 (red daugther card), and I've got no other harware.

I was testing the MSCAN module, writing some code, then downloading it... the I did a few changes to the code and when I went to download it, some error windows appears and this is what they say:

 

WINDOW TITLE: NVM Programming

MESSAGE: The operation has been canceled

 

 

WINDOW TITLE: Elf Loader

MESSAGE: Error while writing to 0..200

               Information: No memory at this address

 

WINDOW TITLE: Hi-Wave

MESSAGE: Failed to load <project path>

 

 

And in the  command window this is what I get:
