Over-the-Air Download (OAD)

The following sections aim to describe the lower layers of OAD software that are common across all protocol stack implementations. This includes the OAD image header, the flash layout, Boot Image Manager, and the oad_image_tool.

Warning

The TI 15.4-Stack OAD does not implement or perform any security or authentication mechanisms as part of the firmware update process. System developers should take measures to adequately authenticate peer devices and only accept and/or apply firmware images transferred from trusted sources via OAD.
