Comment moved to your other post on the same subject: devzone.nordicsemi.com/.../fake-nrf52832
its getting the program. but not running. also reading chip id showing error. i have collect it from aliexpress. same program running on Dk board and one of our other board.
If it's not bough from one of Nordic's distributors, the quality can not be guaranteed. It can be handled incorrectly and have ESD damage and it can even be stolen factory rejects.
