User manual Thyone-I
The zip packages used for this update process needs to be signed by Würth
Elektronik eiSos.
Unsigned update packages, packages not suitable for
Thyone-I or packages signed by a third party will be discarded.
The secure UART bootloader will not allow downgrading to old firmware ver-
sions. It will also not allow installing a Bluetooth Low Energy (i.e. Proteus-III)
firmware on the Thyone-I.
A firmware update will revert to the default the factory settings of Thyone-I.
15.1.4. Update via host
In case you want to enable your own host to perform UART firmware updates, please refer to
the documentation and source codes available from Nordic Semiconductors. Tools supplied by
3rd party providers are not guaranteed to be working with Thyone-I.
There is no generic host firmware updater for Thyone-I available. In case of an update via host,
customers are required to refer to the DFU example and documentation of the Nordic SDK for
an own implementation.
The firmware update package of Thyone-I itself may take up to 1 MB of memory in the host.
Source codes for pc-nrfutil are available from Nordic Semiconductors in Python only. Any other
programming language is currently not available or not supported directly by Nordic Semicon-
ductors.
15.2. SWD interface
This method is for production and development purposes only. Using this interface will invali-
date any certificates, declarations and qualifications of the module.
