GNU ARM Eclipse QEMU v2.8.0-20161227* released

Posted on December 27, 2016 by Liviu Ionescu.

Version 2.8.0-201612271623 is a new release, adding support for active graphical buttons to all supported boards.

Changes

The main internal change is the use of CMSIS SVD files to generate the peripheral registers. This ensures the best possible accuracy in the register bitfields implementation.

New features

• the most compelling new feature is the addition of active graphical buttons; the rectangles around the buttons are sensitive, and moving the mouse over them changes the cursor to a hand; clicking the buttons is also functional, the Reset button triggers a board reset; the user button is also connected to the correspondig GPIO pin, and can be checked by reading the GPIO pin input value; it is also possible to configure the EXTI device to trigger interrupts on GPIO pin changes;
• the STM32 implementation was extended to support the EXTI and the SYSCFG or AFIO peripherals; now it is possible to trigger interrupts on GPIO pin changes;
• the STM32F0DISCOVERY board was added, as a Cortex-M0 board.

Addressed bugs

• [#31] - the GPIO toggling using the ODR register is now functional;
• [#24] - command line options located after --semihosting-cmdline are no longer parsed, but passed to the application.

Known problems

• Ctrl-C does not interrupt the execution if the --nographic option is used.

How to test the buttons

An Eclipse project that can be used to test the STM32F4DISCOVERY button is available from

https://github.com/gnuarmeclipse/eclipse-qemu-test-projects/tree/master/f407-disc-blink

To use it, clone the gnuarmeclipse/eclipse-qemu-test-projects git and import the f407-disc-blink project. Build and run the application; the four coloured LEDs will lit for a second, then turn off; click the blue button; the LEDs will lit one by one. Click the black button; the board will reset.

Download

The new QEMU can be downloaded from the GitHub Releases page.
