Debugger stuck at Hardware fault

We just bought ST-Link to debug our software. Everything works great with Atollic and Seger J-Link with ST32F407 chip.

But when we switch to ST-Link, we can flash the chip, but when start the debugger (in JTAG mode), it stops everytime SVC call is made to switch context with Hardware_Fault.Any ideas?I have tried copying startup script for J-Link into ST-Link and that doesn't help.Thanks in advance #st-link-atollic-seger-gdb

Hi

You are not really suppose to change debugger on the tool chain. Have you tried clean and rebuild? Atollic is an awful toolchain. I suspect is sets lots of internal variables when the project is first set up (including the debugger - hence my comment about not changing debugger). Eclipse (Atollic is built on top of Eclipse) is constantly doing 'stuff' in the background- I hate it. I hate it. I HATE IT!

If the J-Link works why are you fighting the ST-Link? The Segger pod is a far better commercial solution. Make sure you have the most current firmware and drivers for the ST-Link.

Thanks guys. The reason I am changing to ST_Link cuz it's cheap :) My preference is to stay with Segger but company wants me to evaluate a cheaper debugger.

Hi

Yes, I gussed you would be looking because it is cheap. The only think I can suggest is to create a new project with the ST-Link as the debugger. This should create the correct settings for the project from the start. (Just shows what a pile of sh*t Atollic is) I use Atollic and St-Link here where I work. Did I mention I HATE IT! (I used IAR and J-Link at my previous company - much better!)

Yes, I do have latest firmware. When I step through using Segger, I see the handler for Hardware fault.

But when I try the same on ST-Link, it says no such file or directory.

'' When I step through using Segger, I see the handler for Hardware fault. But when I try the same on ST-Link, it says no such file or directory.'' Definitely Atollic getting it's internal nicker in a twist then. What a pile of kack! The new project trick should work in that case. I have never tried to change debugger in IAR before BUT IAR does have a nasty habit of switch to simulator every now and again. Had no problems switching between a J-Link and J-Trace but that is because they are almost identical.

Not a big fan of Atollic here either, bloody Eclipse..

Though last time I priced it, it was still quite expensive. Thought about Rowley? For that matter Eclipse CDT and GNU/GCC (Yagarto) are free and easy enough to integrate. Keil has something at the $2500-2600 range for Cortex parts these days as I recall. eBay often has used and bootleg J-Links
