Hi,

In my project I use CMSIS Ethernet library and use USART as communication channel to talk with other boards. All function work perfectly but after adding FLASH_ReadOutProtection to protect my micro-processor it's execution speed decrease (for example before enabling ReadOutProtection it could process each received Ethernet package less than 50ms but after that it takes more time(about 4times more) to process a simple package.

 

what's wrong with ReadOutProtection ?

 

Thanks
