Problem with serial write

Hi everyone!

I have a problem, that I try to send a command to the MCU (STM32F756), and the transmit is done I checked it with analyzer. But the nothing happens on the mcu site. Howewer when i send the command from tera term it works. What is wrong, is it any properties what i dont know?

serialportObj = serialport("COM17",115200,'Databits',8,"Parity","none","StopBits",1);
%getpinstatus(serialportObj);
%serialportObj.ClearToSend=1
%serialportObj.DataSetReady=1
%setCTS(serialportObj,true);
%getpinstatus(serialportObj)
%setRTS(serialportObj,true);
%getpinstatus(serialportObj)
writeline(serialportObj,'flashmode_on')
delete(serialportObj)

Lacking any knowledge whatsoever about the target, even a link to vendor documentation, it's impossible to know.

But, one possible issue might be the devce is expecting a command terminator character while whatever "tera term" is does so transparently.

Hi Gyorgy,

I tried the model on F767ZI. Receive the data via USART3 and sent it back via USART 2 when data is available.

MATLAB was used to send the data and Putty was used to get back the loopback data.

It worked as expected.

Can you check in the algorithm do you need

1. Flow control which is a name value pair for serialport
2. Configure the terminator
