Marcelo Jimenez wrote an Arduino library to apply XSVF patterns on a JTAG interface using the Arduino as a JTAG adapter. It is especially useful for FPGA/CPLD programming. In the example provided in the GitHub repository, the XSVF file is passed through the serial port using a client-side python script. Some time ago I started some similar […]
Full disclosure: I work at ST Microelectronics, but what I write here is purely my opinion and my work, conceived and conducted in my spare time. The ST Nucleo boards are development platforms mounting an STM32 microcontroller, made for the same enthusiasts that are attracted to Arduino and the like. They have between 64KiB and 512KiB of […]
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.
This new blog called Ångstroms And Algorithms has a complete tutorial on developing and debugging for ARM microcontrollers on Windows. In particular he’s using a STM32-E407 board, an ARM-USB-TINY-H JTAG adapter, ARM GCC toolchain and Eclipse. The tutorial is divided in 4 parts: Free Eclipse ARM GCC OpenOCD Toolchain for Windows Introduction ARM GCC Eclipse IDE GDB / OpenOCD Debugger Personally I am not […]
This post shows how to debug a program running on the Olimex STM32-P152. The setup consists of free software such as GCC, GDB and OpenOCD, and FTDI USB cables.
A great and detailed post about setting up Linux kernel debugging on OLinuXino board: Debugging the iMX233-OLinuXino via SJTAG with OpenOCD — Christian’s Blog.
Dangerous Prototypes recently announced the availability of the open source Bus Blaster v2 in their shop (here the announcement). The Bus Blaster is an USB tool to debug microcontrollers and embedded cores in general, and its design is completely open source. I already did a post on the first version of the Bus Blaster, but […]
The Bus Blaster v1 is a prototype board (from Dangerous Prototypes) that allows to access the JTAG connection of integrated circuits through USB, using the FTDI FT2232H chip for the conversion. The prototype is on sale at around 35$ as they say on their page, but keep in mind that it is still a prototype, […]
A tutorial that shows how to debug an ARM Linux program inside a platform emulated with QEMU. The tutorial uses gdbserver to connect the program executing in the guest system to the debugger running on the host system.
Using Icarus Verilog and a custom built GDB to debug software running inside a simulation of a OpenRisc System On Chip, thanks to the Verilog Procedural Interface.
