BOOSTXL-CC3120MOD: updating servicepack

Part Number: BOOSTXL-CC3120MOD
Other Parts Discussed in Thread: CC3120MOD, LAUNCHXL-CC26X2R1, CC31XXEMUBOOST

Hello,

If I understand it well the CC3120MOD can be updated with new service pack by uart and by SPI. 

By SPI for example by XDS110 programmer ( I have LAUNCHXL-CC26X2R1 development board available).

By UART for example by CC31XXEMUBOOST evaluation board.

What is the simplest way to update a CC3120MOD chip at production level?

The uart connection is used as host controller interface.
SPI connection is not used functional.

Greetings Peter
