Help¶

When enabled log is processed in the context of the call. It impacts performance of the system since time consuming operations are performed in the context of the log entry (e.g. high priority interrupt).Logger backends must support exclusive access to work flawlessly in that mode because one log operation can be interrupted by another one in the higher priority context.

Direct dependencies¶

(LOG && BOARD_NATIVE_POSIX) || (LOG && BOARD_NRF52_BSIM) || (!LOG_MINIMAL && LOG)

(Includes any dependencies from ifs and menus.)
