Unable to start debug using Open OCD

[SSaur]

Hi

I am using STM32L476VG micro controller on STM32L476 Discovery board.

I just configured the Eclipse project to build using arm gcc and successfully compiled the code to generate binaries. I am facing issue to debug the code.

I have attached console log for more information.

Please help

Thank You

Hi there,

same topic: .... Unluckily, I am not allowed to ask a new question regarding Openocd issues (is that not the point about communities? The "ask a question" button was not greyed out...), so I attach my question here.

build error when setting up Openocd in Eclipse

make: *** [system/src/stm32l4xx/stm32l4xx_hal.o] Error 127

system: Mac, Eclipse, gcc, STM32L476 nucleo-64 with STM32L4476RG 64 pins

I am new to programming µC. Following the instructions of an old udemy course I got above mentioned message. Of course, different versions of Eclipse, Openocd etc. are used. I got stuck, as I do not know where to search for faults.

The lecture tries to set up Eclipse for use with Openocd and confirming with the debug of a blinky project. At an earlier stage, building of blinky was successful. After starting Openocd as "external tool" in Eclipse I got an error message.

The console throws out:

10:39:59 **** Build of configuration Debug for project Blinky-STM32L476 ****

make all

make: *** [system/src/stm32l4xx/stm32l4xx_hal.o] Error 127

"make all" terminated with exit code 2. Build might be incomplete.

10:39:59 Build Failed. 2 errors, 0 warnings. (took 87ms)

I double checked the paths in "external tools configuration", but could not find anything conspicious. Using a mac, I filled in "openocd" only instead of adding the extension .exe as mentioned in the lecture (which was for Windows-PC) when setting up the location for the external tool:

(...) /openocd-esp32/bin/openocd

I was not sure about the point working directory, as the openocd folder structure of my up to date version is slightly different to the one shown in the old online course. The scripts folder is in a deeper branch in the version of my openocd folder So, what is the proper "working directory" path for the make process? But I assume this is not the issue causing the error.

Any help is warmly welcome!

Ciao Andreas
