The specific architecture is ARMv6-M. The SAM C21 microcontrollers use little endian. There are two buses present; AHB, Advanced High-performance Bus and APB, Advanced Peripheral Bus. Some peripherals are connected to both of the buses, most are only connected to the APB. text/html 2022-09-12T00:30:54+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.jegatron.se/doku.php?id=arm:stm32&rev=1662942654&do=diff Minnesanteckningar för att komma igång med STM32F0xx Länkar att spana in <https://electronut.in/stm32-start/> <https://freeelectron.ro/arm-cross-compiler-tutorial-stm32/> och <https://freeelectron.ro/bare-metal-stm32-led-blink/> <https://web.eecs.umich.edu/~prabal/teaching/resources/eecs373/toolchain-notes.pdf> <https://jacobmossberg.se/posts/2018/08/11/run-c-program-bare-metal-on-arm-cortex-m3.html> MSYS2 & OpenOCD MSYS2 Kom ihåg att öppna via genvägen MSYS2 MinGW 64-bit, annars fung… text/html 2022-09-12T00:30:54+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.jegatron.se/doku.php?id=arm:stm32f3discovery&rev=1662942654&do=diff STM32F3discovery MCU: STM32F303VCT6 ARM core: ARM Cortex-m4 ARM architecture: Armv7E-M STM32CubeIDE STM32F303VC -- Drivers and stuff for the MCU. stm32f3discovery -- Product page for the development board STM32F3 HAL reference manual Features * LSM303AGR -- 3D accelerometer and 3D magnetometer * I3G4250D -- 3-axis gyroscope General No external crystals are mounted. text/html 2022-09-12T00:30:54+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.jegatron.se/doku.php?id=arm:toolchain&rev=1662942654&do=diff General GCC Online documentation Good options Command line options, Arm options * -march=armv6-m * -mtune=cortex-m0plus * -mcpu=cortex-m0plus * -mlong-calls * -mthumb * -mno-unaligned-access * To find unused functions: -ffunction-sections -fdata-sections -Wl,--gc-sections,--print-gc-sections
