Hi Peter,

[quote user="peter.min"]2.What firmware can be burned into nRF9160 to enable nRF9160 to update app core hex firmware via serial port?[/quote]

mcuboot can be used for this purpose, either via the "smp_svr" example (link) with serial backend, or by using the serial recovery, like thingy91 does. Here's the mcuboot configuration for thingy91, which enables serial recovery:

Kind regards,

Håkon

Hi Håkon Alseth,

1.I have learned that nRF9160 without burned program cannot update hex firmware in app core via serial port.

2.What firmware can be burned into nRF9160 to enable nRF9160 to update app core hex firmware via serial port?

Thank you for all your assistance.
Kind regards,

Hi,

All ICs are delivered blank from us, so you must initially program them using the SWD interface.

Kind regards,
