Part Number: LAUNCHCC3220MODASF
Hello all,
as I understand it correct, the TI default Trusted Root Catalog is used:
- to check the TLS server connections (CC3220 is the client)
- to verify that the MCU firmware file mcuflashimg.bin is signed by a TI well know CA (included in the TI Trusted Root-Certificate Catalog)
Right so far?
To activate the signature verification of the mcuflashimg.bin signed by a certificate that is inside the Trusted root catalog I must set:
- the default Trusted Root-Certificate Catalog in the UniFlash project settings
- the signature file for the mcuflashimg.bin to a certificate that is derived from a TI known root CA (included in the TI default trusted Root-Certificate Catalog file)
Right?
It is possible to subsequently activate the usage of the Trusted Root-CA signature verification process for the mcuflashimg.bin by an OTA update?
For example for an device that was flashed with an image that used the playground certificates instead of the Trusted Root catalog?
Many thanks,
Roman
