Software Image Handler

Parts have been written, but some important components still missing. Architecturally, the image handler has 2 primary modes:

Image Copying Engine:

• There are 3 binary slots per SD card. Implement and/or test command to replace one slot with another (e.g overwrite primary slot with update)

Scrubbing Engine:

• Implement scrubbing of NOR-Flash image using sent hamming code
• Implement scrubbing of SD-Card image using sent hamming code
• Optionally: Automatic periodic scrubbing?
