Firmware Upgrade over BLE
• The TI CC254x style upgrade is based on the idea of three sections in code. First off is a
Boot Manager, which decided which image to run. This manager is never updated. The
other two sections are labeled Image A, and Image B. On Power up the Boot manger
decides which image to run. When it is time to update the device, the code in running
image allows for the other image to be erased (in other words, if Image A is running, then
you can only update Image B). Once Image B is updated and verified as good, Image A
will be tweaked so it no longer passes the CRC check. Now the boot manger will run the
newly updated Image B. On the next update, Image A will be erased, updated, and once
verified.. run.
Required Items

o A Image A and Image B File, can be compiled with scons via
