Hello, 

   

I have flashed the EZ-Serial image onto my CYBLE-012011 evaluation board from here. I connected USB-UART to pins P3.4 and P3.5. I opened the COM port on putty and did a RESET(shorted XRES to ground ). According to the firmware guide in here(page 8), the factory default behaviour should give a boot message like 

@E,0032,BOOT,E=0100,S=030100C2,P=0100,C=01,A=00A050E3835F 

But I am not seeing any output on the COM port. Also the guide says that local echo is enabled. I can't see anything being printed on the console when I type in. How does this work?

Thanks
Dheeraj

Hi Dheeraj,

   

The correct pins to use for UART host communication are P1.4 (RX) and P1.5 (TX), and optionally P1.6 (RTS) and P1.7 (CTS). Refer to Section 8.1 in the EZ-Serial User Guide for details on which pins perform which functions. Note that P3.4 and P3.5 are used for other purposes.
