ChibiOS Free Embedded RTOS

Hi friends,
May you please give me some times to help.
I am trying to debug stm32f407 using Eclipse, openocd, and stlink.
During the debug, I got that error (image file)
Do you know the reason for that problem, I think problem is in halInit() function.
Thank you so much.

I think, you are using GDB for x86, this is why it fails.

Not sure, are you using ChibiStudio or a self built toolchain? You may try our pre-configured VM and verify differences.

Hello Giovanni.
I am not using ChibiStudio. I am using Eclipse Luna, Openocd 0.10 and Chibios 3.0.2. So, I built toolchain by myself.
Yesday, when I tried to program for led blink, but the program did work incorrectly. In this program, for thread function, I just blink 1 led, and in the main loop, just checked button status. Then the led could not blink. So, I think there are some problem in configuration or init, but I did not know where.

How can I use your pre-configured VM?
Thanks

Self-built toolchains are a common cause of problems, we recommend using GCC built by ARM, they do patching on top of release code:

https://launchpad.net/gcc-arm-embedded

The VM is available here, all you need is VirtualBox, user/pass are chibios/chibios, launchers are in the task bar:

https://osdn.net/projects/chibios/releases/71386

You need to combine the 3 files in a single file:

cat VM_*.7z.* > VM_LinuxMint19.2_with_ChibiStudioP2.7z

Please see the whole discussion here, there are hints: viewtopic.php?f=3&t=5176

Thank you so much for your rapid reply.
how can I install VM in VirtualBox? Do you have any tutorial?
I will try VM.

Before I use ChibiOS. I tried to program stm32f407 for led blink using Eclipse, openocd, and arm-none-eabi-gcc. And it worked well. But for now, I made that error.
So I think the the problem is from gcc.
what do you think about that?

That is a real possibility. There is a wide range of compilers that Giovanni is not happy with because they mess up the "task switching code" or something like that.

In the past it happened several times that self-built GCCs or GCCs included in various Linux distros repositories didn't work very well.

This is why ChibiStudio exists, we are not interested in creating a toolchain, its purpose is to provide a known starting point for everybody.

Anyway, better start from a known compiler: https://launchpad.net/gcc-arm-embedded , it is maintained by ARM developers so it is the safest choice.
