Flush the current LittleFS log file(s), forcing a write to flash.

Note

This function is meant to be called periodically in an RTOS task.

This function can be called very frequently. It tracks its own internal configuration.

LOG_to_file_lazy()

void LOG_to_file_lazy	(	const char	filename[],
		const char	msg[] )

Write a log message to an LFS log file.

Parameters

msg	The message to be logged

Note

LFS files are not updated until the file is closed or synced. Syncing is done periodically in the rtos_background_upkeep task.
