Question
When I downloaded the bit file with MYD-C7Z010/20 development board, the download was intermittent. Sometimes the development board could be detected and sometimes it couldn’t be detected. When I run the hello_world program after power on, the development board kept printing hello_world. What’s the problem?
Answer

This is because on the CPU Module of this development board, JP1 jumper is connected to watchdog. If JP1 is not disconnected, the development board would be reset all the time, this cause the development board cannot be detected. When you run the program, the development board will keep resetting and restarting, so it will keep printing hello_world.
