Cannot debug Nucleo-F767ZI board... (Read 2993 times)

	The debug session for my F767ZI board fails with a popup stating "Unable to start debugging. The value of miDebuggerPath is invalid". I'm Running VS2017 with vMicro 1912.28.1. I can upload using the onboard STLink. Using Zadiq I updated "ST-Link Debug (Interface 0)" from 2.1 to 6.1. There are 2 other ST-Link interfaces (USBSTOR and VCP CTRL) that I did not update. Prior to Zadiq update, I could connect to the ST-Link 2.1 using ST Cube Programmer, after update to 6.1 I cannot connect. I am able to debug another board, an STM32F103, using an external ST-Link V2, and the V2 is detected by ST Cube Programmer. Any assistance appreciated, IK

	Thanks for the information so far and the driver installation sounds correct, but the tools used to connect aren't found is definitely a problem from the error. Just to help us further, could you attach the contents of the Output Window: 1) "Micro Build" when you try to attach the debugger? 2) "Build" when you build the project? (with verbose options enabled as shown in yellow at the top of the page)

	Apologies for not attaching those before. My 'Build' output is empty, both of the attached files are from 'Micro Build'. One from a Build and the other from Start Debugging. Thanks for the quick response, IK

	Thanks for the files, I can see I have forgotten to mention an option.... Can you set the vMicro > Uploader > Verbose to On and then try to attach the debugger again? (and attach the new log from Micro Build) This should add some additional JSON output on the end, which will show more detail of where the issue lies.

	Hello, the requested file is attached. Also attached is a screenshot of the directory structure around one of the tools directory. Indeed, the directory does not exist, the 'bin' subdir is missing. I did not create the _BAK directory, I'm not sure what application did. The non '_BAK' directory does have a 'bin' folder. If I copy the bin folder into the _BAK directory I get a different popup stating "Unable to start debugging. Unable to establish a connection to GDB. Debug output may contain more information." I've run out of attachment slots so I can't attach the micro output from that attempt. Thanks again for your assistance, IK

	Apologies for the delay, and thanks for the additional output and information. Can you try re-installing the SAM or SAMD core which installed these tools? (not sure why the _BAK folder is there, and this is the main reason it isn't working as expected) Once that folder is correct, and it contains the "bin" tools as expected, the board will also need an additional element (we will resolve in a future build), to ensure the target config is correct: Right Click on Project Add > Local Boards.txt Add the entry "build.openocdscript=target/stm32f7x.cfg" to the Boards.txt file. Once this is done the debugger should launch as expected...
