Does K22F micro controller supports hardware reliable update feature?

Hi, 

 

I went through KBOOT source and found that it's hardware reliable update functionality which uses micro controller's flash SWAP feature. I found no support for flash swap feature (command 0x46) in K22F; which means i can not perform hardware firmware update on K22F microcontroller. 

 

Is my understanding correct or I am missing something here ?

 

Thanks, 
Swapnil Pendhare

Hi Swapnil Pendhare,

The ReliableUpdate command has supported software and hardware implementations, the hardware approach doesn't work if the device doesn't support the flash swap feature and only option is the software implementations.
