Hi ,
one of my customer met the F28069 using problem, and the problems show as below:
they can not download the program when using the serial port. GPIO37 was set to Low and GPIO34 was to high,and TRST is configured as low level. The chip will be re-energized and reset before downloading.
The serial port downloading tool is USB to TTL, the power supply voltage is 3.3V, and the software is C2prog.
more info pls see the screenshot as below:
could you give me some suggestion?
BR!
