STM32VL Debug

[StuntMonkeh]

I am trying to run the demo code for the STM32VL board using ChibiStudio.



What am I doing wrong?

Hi,

I see two problems there:
1) You have to select the project right before launching the debugger, it is an Eclipse quirk. That message is caused by that.
2) You have to select ST-Link V1. V2 is for newer Discovery kits.

I got a step closer. After I select 'stm32vldiscovery.cfg' I get the following error in the console.

If I remember well somebody else reported this problem with the VL, I don't have one at hard to make a test. This issue is probably not specific of ChibiStudio but more general with OpenOCD.
You may try to search in the OpenOCD forum and mailing list if similar problems have been reported for the ST-Link V1.

Anybody else could make a test?

For ST-LINK v1, you have to replace default Mass Storage drivers with the WinUSB or libusb drivers using the zadig utility.

This should solve it for you.

I tried both drivers. Unfortunately they didn't work. I have tried on two different PC's, always the same problem.

I can see how its a OpenOCD problem but I dont know how to fix it.

Hi, is there any update on what exactly shall be done to run debug with stm32vldisco and the newest CBS5?
Getting error (as above) with any .cfg related to stm32f1.. from target dir..

PS: I've installed the https://sourceforge.net/projects/libwdi/files/zadig/ utility and updated the old driver with WinUSB driver. It does something now..
PS1: I had to set Option>List All Devices (in zadig's tool) in order to see the old driver (while stm32vl connected and all other usb stuff disconnected) and then replaced with WinUSB.

I cannot get it working, however. The stlink communicates, but I get errors like:

Ok, I have to choose the stm32vl "board" .cfg, not the "target" .cfg.. Confused by the word "target" in the openocd dropdown item description..
