Hello to all,

We are currently using the Upgradable Stack OTA and are planning to add external flash to use external memory OTA. Currently we have launcher, stack and application. But in the external OTA I see there is only bootloader and application. From the HW perspective we already prepared it for the external memory OTA, but did not have time do to also the SW changes. Can we use OTA approach to switch from the upgradable stack OTA to the external memory OTA as now some customers are already using the device? It would not be a problem if the launcher would still remain in the flash. Or must we use programmer for flashing?

Thanks for the answer, Frenk

No, it won't be possible to use OTA approach to switch from upgradable stack OTA to external memory OTA.

Please use a programmer to switch to external memory OTA.
