nexpaq 1:55a6170b404f 14 * The stack size is defined in cmsis_os.h mainly dependent on the underlying toolchain and
nexpaq 1:55a6170b404f 15 * the C standard library. For GCC, ARM_STD and IAR it is defined with a size of 2048 bytes
nexpaq 1:55a6170b404f 16 * and for ARM_MICRO 512. Because of reduce RAM size some targets need a reduced stacksize.
