Not enough information to list image symbols.

Getting error for vTaskDelayUntil taskPosted by rtel on December 29, 2015 vTaskDelayUntil() is implemented in FreeRTOS/Source/tasks.c (that is
what the 'Task' in the function name means). You can search for the
function in that file to see that it has a dependency on
INCLUDE_vTaskDelayUntil.
Pre-processor symbols that remove entire functions are generally a waste
of space anyway, as most linkers will automatically remove functions
that are not referenced. The only toolchain I know that doesn't do that
by default is GCC - but most people (and GCC vendors) that use GCC
manually set the compiler options to remove dead code.
