STM32-P152 development with Eclipse on Linux

February 23, 2014

In this post I show how to use Eclipse to create a simple "blink" program, flash it on a STM32-P152 board and attach to it with a debugger. This has been executed with the help of Eclipse plugins, GCC ARM Embedded toolchain, OpenOCD, C232HM FTDI JTAG cable. This approach can be adapted to many Cortex-M targets and many JTAG adapters.

Using the CodeSourcery arm-none-eabi toolchain to compile a minimal "Hello World" example for Stellaris lm3s6965 microcontroller. The microcontroller is emulated through QEMU and the output is written to a serial port.

ARM Cortex-M3 boards with STM32 chip

The ARM Cortex-M3 is the baseline of ARM 32-bits microcontrollers. Many products spawn from its design: the Cortex-M0 (a stripped-down version for small systems), the Cortex-M1 (specifically designed to be implemented in FPGA) and the Cortex-M4 (with Digital Signal Processing extensions). One chip family that contains the Cortex-M3 is the STM32. STMicroelectronics recently introduced the […]
