Dear all,

Is it possible to loas s-record into flash of the QY4A without using usb-Mon-08 from P&E or cyclone pro.

Is it possible to use monitor mode entry ckt available in datasheet to program the flash of controller.

The security feature is very confusing in it.It says that to load data into flash the security bits has to be entered into flash

locations FFF6-FFFD,but these locations are ISR vector addresses.Please some could clarify on these things.

Hello and welcome to the fora madhub.

Yes this is possible.

To get past security you must send the same value as is programmed into these vector locations at the appropriate time.

You can get a free programme to do this from here.
