The source file you copied here, is that from an nRF5 SDK? If yes, which version.

1. I tried to debug step by step. fs_initialized = true is retained till the execution comes out of while loop when the file_index < MAX_INDEX condition becomes false! I did a workaround by initializing fs_initialized = true after fs_data_reset(false). But this is not correct way. There might be other areas where the variable value changes and thus the application is not working as intended.

2. I made it and it is the same. But when I change the optimization level from none to any other option, it works!

I does clean and re-build very often.

1. I don't have any explanation to 1, maybe try and fail a bit to see if there is any code that is updating fs_initialized, for instance by adding some debug output each time fs_initialized change or set value.

2. You can try to make file_index volatile also.

Sometimes a clean and re-build (Alt+F7) can help.
