Run/Debug problem in SW4STM32 using ST-Link/V2 SWD

Posted by mostafanfs on 2015-10-28 18:50

I’ve just started using SW4STM32 and wrote a sample project to check it out but after setting up my board and its connection and a Run/Debug configuration I got this error when I want to deploy my program using ST-Link/V2 SWD:

I can program the chip using every other tools I have on my computer like Keil and STM32 ST-LINK Utility pretty easy and I wasn’t expecting any problems at this stage!
ST-LINK has the latest firmware and I have installed the latest ST-LINK USB driver so I sort of blame SW4STM32.
Any thoughts?

Just make a copy of your project *.cfg file in the same directory and remove this phrase in your new file
srst_only
select the new file in the second tab of your project debug configuration instead of default *.cfg file and you’re good to go.

Thanks, this actually worked for me. I can now debug my custom board in sw4stm32 eclipse IDE

I am developing a very important application using System workbench.

I can not tell you the number of times the debugger fails to load, it is constant. Why? Who knows. Why does it start working? Who knows. It just does.

This is a HUGE problem and from what I can tell no one seems to care in the least.

When I switched to Linux I thought perhaps it would work better, nope. Still just as bad.

My release was yesterday, and I can’t fix the problem because the debugger just says “Error erasing flash with vFlashErase packet”.

What does this mean? No one knows. How do I fix it? No one knows.

I have found that to get more information click the down-arrow next to the console icon, then select the gdb traces console, or the openocd console.

The openocd console says “Error: timed out while waiting for target halted”.

What does that mean? Dunno.

This is why it is free.
