Translate the query first:
We have added the OTA function in CYBL11573. While power on and power off the chip quickly, chip crashed. Only download the FW again can recover it. We suspect the Flash has crashed. But delete the OTA function can solve the issue.
Have you check the difference between the flash data in normal and abnormal situation? If yes, what's the result ？
Which type of OTA do you use: Fixed stack or Upgradable stack OTA?
Generally speaking is the flash programming always sensitive to power losses: programming consists of a sequence of (row-wise) erase and a new programming. Even a low-power detect will not help, since a program cycle often cannot be interrupted. A solution can be to detect a power loss on the primary side of the power supply and keeping the PSoC supply voltage stable until the current program row cycle has finished.
