Secure Firmware Update for PSOC4?

[vegan_electron]

Dear forum members,

we would like to update the firmware trough OTA. We actually do this but now it's required to handle an encrypted firmware.

As far i have seen PSOC4 is not supporting this. Means we have to switch the platform maybe to psoc5 or so? Or is there

a better solution which doesn't end up in so many changes in the electric schematics? Read there is required an external

memory.

Thank you for any advice. Kind regards,

Daniel

CE222802 - PSoC 6 MCU Encrypted Bootloader supports encrypted firmware bootloading or with encrypted signature. PSoC 4 do not have any CRYPTO block. Instead you can use custom/external libraries.
