How to protect the firmware in the external flash from being read

Jump to solution

Hi all:

as we know, there is no internal  flash for the CYW20735, we should  store the firmware in the external SPI flash,

however the firmware is easy to be read from the external flash and may be artificially modified, so how can we let the device

boot safety!

thanks!
