As well as the more common "A-profile" CPUs (which have MMUs and will run Linux) we also support the Cortex-M3 and Cortex-M4 "M-profile" CPUs (which are microcontrollers used in very embedded boards. Maybe silly question: I was wondering: if I cast a pointer to a uint32_t to an array "buff" of uint8_t, what is held in buff [0], MSByte or LSByte? Or in other words, what is the endianness on. STM32 Cortex®-M4 MCUs and MPUs programming manual Introduction This programming manual provides information for application and system-level software developers. Select Architecture¶-march =<arg> ¶ Instruct the compiler to generate code for the Arm architecture variant indicated by <arg>, where <arg> can be: thumbv6m - appropriate for -mcpu=cortex-m0 or -mcpu=cortex-m0plus. The Link Register (LR) is register R14. out file can be loaded and run on a TI Arm Cortex-m4 processor (like MSP432E4, for example). fpv5-sp-d16 - available in combination with -mcpu=cortex-m33. For the Cortex-M3 and Cortex-M4 processors the NVIC supports up to 240 interrupt inputs, with 8 up to 256 programmable priority levels (also shown in figure 4).
