on page 19 of the board manual (request ERG-00328-001). The following
is a summary of that information:
- Connect ICE and establish connection to it from WorkBench/OCD.
- Ensure you have background mode (BKM) in the OCD terminal window.
- Select the appropriate flash type (listed above)

Convert from FF80_0000 to FFFF_FFFF (or to FF83_FFFF if you are
trying to preserve your old environment settings and user flash).
- Set the start address of the erase/flash process to FF80_0000
- Set the target RAM required to 64kB.
