upload failure on vmemega v1a

[mfe5003]

Upload to vmeMega board fails using:
$ make upload_<target name>
, but succeeds with normal r3 mega board.
Workaround is to disable flash memory erase by adding -D option after the avrdude command.
To get avrdude command run the next line and copy-paste:
$ make upload_<target name> VERBOSE=1

output of $ make upload_<target name>:

avrdude: Device signature = 0x1e9801
avrdude: NOTE: "flash" memory has been specified, an erase cycle will be performed
         To disable this feature, specify the -D option.
avrdude: erasing chip

avrdude done.  Thank you.

Temporary fix applied by adding -D to all avrdude calls.
You can now upload to a VMEMega v1a with the standard procedure of:
$ make upload_<target name>
