I need help on grayed out part of the code

[demir]

Hello All,

I am working on open bootloader. I have copied all required files. When I compile the code on demo project provided by open bootloader, it works just fine. On the other hand, when I compile on my own project, I get the following error.

I have compared files and I have noticed that even though I have copied the exact same files, my file has grayed out parts, unlikely to the original file. How can I make the grayed out part seen as normal (white) ?

Could you please guide me with that ?

Hi,

seems in your copy missing the define:

#define USE_FULL_LL_DRIVER

[demir · Accepted solution]

Hi,

I have found the issue. The copy is correct actually, but the build settings are different. So, the solution is to add USE_FULL_LL_DRIVER into project --> properties --> settings --> C/C++ Build --> settings --> MCU GCC Compiler --> Preprocessor --> Define symbols (-D). Click Add, and type USE_FULL_LL_DRIVER.
