 ## Using mdloader
 
 To work with this repo's fork of mdloader, build and run the ```mdloader``` tool with ```--list```. I have patched the code to show *all* of the chip ids for boards found. Once you have the chip id, edit ```mdloader_common.c``` and change the chip id as necessary. Rebuild the tool and run per the standard documentation.
