Hi

We are trying to implement OTA2 on modified WM-BN-BM-22 module which has STM32F412 microcontroller, 256KB SRAM, 1MB internal flash, 4 MB external QSPI flash. QSPI flash is memory mapped and can be used for code and data. Could you suggest what would be configuration and other changes required and also let us know if any reference platforms in SDK use a similar configuration.

Thanks

Hemanth

Hello Hemanth,

Please have a look at the OTA2 document in WICED doc directory. The external flash requirements for OTA2 is nearly 8MB.

Would you recommend earlier OTA process (ota_fr) instead of OTA2
