Does SFLASH Encryption Disable the Serial Port Input? (CYW943907AEVAL1F)

[ChMa_3922746]

I have a quick question: Does anyone know if enabling SFLASH encryption disables the serial port input?

When I add SECURE_SFLASH=1 into the make command, then it appears that the serial port outputs data, but no longer accepts input from the console.

hello:

  did you try the command console app for the input test ?   and disable all the flow control flag like RTS/CTS .

Thank you for the suggestion.  I tried it out and saw that it was not an SDK issue because the console app worked fine when encrypted.

I did some digging and found that the problem was the way my UART RX routine was coded.  When I reverted back to wiced_uart_receive_bytes(), it worked fine with secure SFLASH enabled.  Case closed!
