QEMU with STM32 Microcontroller Implementation Official Homepage: http://beckus.github.io/qemu_stm32/ OVERVIEW This is a copy of QEMU that has been modified to include an implementation of the STM32 microcontroller. It also implements an Olimex STM32_P103 developmentvboard. This project runs the demos located in the stm32_p103_demos project located at: https://github.com/beckus/stm32_p103_demos . Commands for a typical build: ./configure --enable-debug --target-list="arm-softmmu" make Useful make commands when rebuilding: make defconfig make clean If you receive a warning during compilation, this may cause the build to fail. In this case you can pass the following option to the "configure" command to ignore warnings: --disable-werror The generated executable is arm-softmmu/qemu-system-arm . Other configure options which control the STM32 implementation: --extra-cflags=-DDEBUG_CLKTREE Print out clock tree debug statements. --extra-cflags=-DDEBUG_STM32_RCC --extra-cflags=-DDEBUG_STM32_UART --extra-cflags=-DDEBUG_STM32_TIMER Print debug statements for specific peripherals. --extra-cflags=-DSTM32_UART_NO_BAUD_DELAY Disable the BAUD rate timing simulation (i.e. the UART will transmit or receive as fast as possible, rather than using a realistic delay). --extra-cflags=-DSTM32_UART_ENABLE_OVERRUN Enable setting of the overrun flag if a character is received before the last one is processed. If this is not set, the UART will not receive the next character until the previous one is read by software. Although less realisitic, this is safer in case the VM is running slow. Other QEMU configure options which are useful for troubleshooting: --extra-cflags=-DDEBUG_GIC qemu-system-arm options which are useful for trobuleshooting: -d ? To see available log levels -d unimp,guest Enable logging to view warnings when an unimplemented register is accessed or when an invalid register access is attempted. This is especially useful since many registers are not implemented. -d cpu,in_asm Enable logging to view the CPU state during execution and the ARM instructions which are being executed. I believe --enable-debug must be used for this to work. By default, you can find the output in /tmp/qemu.log: UNIT TESTING Unit test scripts are included for the STM32 implementation. These test will be executed when running "make" with the standard check targets (see tests/Makefile for documentation of QEMU's unit testing features): make check make check-qtest-arm DOCKER CONTAINER A Docker container containing qemu_stm32 can be built from the Dockerfile: docker build . -t qemu_stm32 It can run the examples in stm32_p103_demos: docker run --rm qemu_stm32 /usr/local/bin/qemu-system-arm -M stm32-p103 -kernel /stm32_p103_demos/demos/freertos_singlethread/main.bin The original QEMU README follows: Read the documentation in qemu-doc.html or on http://wiki.qemu-project.org - QEMU team
