Hello,
I was trying to set up my computer to run some program on a STC89C52RC board, but something strange happed when I uploading the program. When I use Platform IO to upload the program, it will proceed to "Cycling power: done“ and my board shut down before I do anything. The word “done” appeared with “Cycling Power:”. At this step the power button won’t do anything when I press it. And the board will when back to normal when I stop the program manually in Platform IO or I disconnect and reconnect the USB cable.
But the same thing won’t happed when I use terminal to upload the program, the word “done” won’t pop up before I restart the board, and the program will run on the board with no issue. Can anyone help me with the problem?
Attached is an example of where I get stuck with the program:
