Hi. I have the following code which runs perfectly on several C IDEs ( including Eclipse, Dev-C++, Code:Blocks and on the Linux Terminal using gcc as well ). However, when I put it on the board ( using either Keil or Eclipse ), the board does not give back any results. The Expected results and the results being obtained are shown below:
Code:

The Expected Results are:

Array Index 2 has value 1
Array Index 3 has value 2
Array Index 4 has value 3
Array Index 5 has value 4
Array Index 6 has value 5
Array Index 7 has value 6
Array Index 8 has value 7
Array Index 9 has value 8
Array Index 10 has value 9
Array Index 11 has value 10
SIZE: 16 LENGTH: 11
Array Index 1 has value 11
Array Index 2 has value 12
Array Index 3 has value 13
Array Index 4 has value 14
Array Index 5 has value 15
Array Index 6 has value 16
Array Index 7 has value 17
Array Index 8 has value 18
Array Index 9 has value 19
Array Index 10 has value 20
SIZE: 16 LENGTH: 10
Program Complete. Going into infinite while loop...
Results that are coming via UART from the nRF52 board are:
Starting Program...
Array Index 1 has value
Array Index 2 has value
Array Index 3 has value
Array Index 4 has value
Array Index 5 has value
Array Index 6 has value
Array Index 7 has value
Array Index 8 has value
Array Index 9 has value
Array Index 10 has value
Array Index 11 has value
SIZE: 16 LENGTH: 11
Array Index 1 has value
Array Index 2 has value
Array Index 3 has value
Array Index 4 has value
Array Index 5 has value
Array Index 6 has value
Array Index 7 has value
Array Index 8 has value
Array Index 9 has value
Array Index 10 has value
SIZE: 16 LENGTH: 10
Program Complete. Going into infinite while loop...
This shows that the the board is failing to either store the values or is not able to read them back..... Please help.
