I have a Nano 33 IOT, and for something that I have in mind to try I need to load an SSL certificate on it.
Reading around, this can be done with the Firmware Updater which is available in the Tools menu of the IDE. There is also an associated FirmwareUpdater sketch which is part of the WiFiNINA library. More on this later. There is also a CheckFirmwareVersion sketch with the same library. Running it it produces this output
WiFiNINA firmware check. Firmware version installed: 1.2.3 Latest firmware version available : 1.2.1 Check result: PASSED
Note that the output does not make sense
Running the FirmwareUpdater sketch produces this output
Unable to communicate with ESP32 boot ROM!
Obviously this is not a good sign either
Running the Firmware Updater from the menu produces this screen from which the Nano 33 IOT selectable but it does not appear in the "select firmware" list
Selecting Test Connection produces this error message
However, the FirmwareUpdater sketch is loaded on the board and has been compiled, see above
Just to be sure I clicked on the Open Updater sketch button but nothing happens
Background information :
Genuine Nano 33 IOT - loads and runs WiFiNINA examples OK
IDE version 1.8.10
WiFiNINA library version 1.4, which is the latest version on GitHub
Has anyone got any ideas how to update the firmware/load SSL certificates ?
There are previous threads on here asking for help with the same problem but none was forthcoming
