I'm using CYW20721. My application which supports OTA is around 750Kb. Since the total internal flash is 1Mb, I think it's not possible to do a OTA FW Upgrade coz my new app will also be around the same size.
Is there a provision to connect an external flash to the CYW20721? I want to connect an external flash of size 2Mb (Will stop using Internal flash 1Mb then).
If connecting an External flash is possible, does this need any changes in the SDK?
