When I build my first blinky sample, I met a error and correct it with (https://devzone.nordicsemi.com/f/nordic-q-a/120279/update-to-ncs2-9-1-compilation-error/529668). It built successfully but an warning occurs (TFM_VERSION_MANUAL mismatches to actual TF-M version. Please update) . I wonder why this warning happened and may it has some influence on my project?
