RTOS/CC2640R2F: After CC2640 OAD upgrade, how to prohibit CC2640 OAD
If you're concerned about illegal firmware, you can use the Secure OAD feature to only allow signed images on your device. (Link to documentation: dev.ti.com/.../index-ble3-cc2640.html )
If you only want to allow one OAD, you can disable the OAD Service from the new image. (I.e. update to a firmware image with no OAD capabilities.)
