available runners in runners.yaml:
openocd, jlink
default runner in runners.yaml:
openocd
common runner configuration:

• build_dir: C:\Work\zephyrproject\zephyr\build
• board_dir: C:/Work/zephyrproject/zephyr/boards/arm/stm32f072b_disco
• elf_file: C:\Work\zephyrproject\zephyr\build\zephyr\zephyr.elf
• hex_file: C:\Work\zephyrproject\zephyr\build\zephyr\zephyr.hex
• bin_file: C:\Work\zephyrproject\zephyr\build\zephyr\zephyr.bin
• gdb: C:/gnuarmemb/bin/arm-none-eabi-gdb.exe

To Reproduce
Steps to reproduce the behavior:

1. Follow initial setup here - https://docs.zephyrproject.org/latest/getting_started/index.html
2. install openocd - https://docs.zephyrproject.org/latest/guides/debugging/host-tools.html#openocd-debug-host-tools
3. use west flass. See error log output in console log

@Sergi22 Seems that west complains on a path issue.
Can you provide the list of the west commands you run ?
Additionally, you could run commands in verbose mode for more information on your setup (west -v flash ...)

Hi @Sergi22,
West flash is working properly on my side.
As said @erwango, it looks like a path issue, so can you make sure you added openOCD binary directory to PATH environment variable (There is a mistake in the documentation it must be added to 'PATH' and not 'Path'):

On Linux, openocd is available though the Zephyr SDK. Windows users should use the following steps to install openocd:

• Download openocd for Windows from here: OpenOCD Windows
• Copy bin and share dirs to C:\Program Files\OpenOCD\
• Add C:\Program Files\OpenOCD\bin to ‘PATH’

Please run this command echo $PATH and verify it contains the openOCD directory.

[Sergi22]

Problem solved, C:\Program Files\OpenOCD\bin was recognized as a PATH variable only after Windows reset. Currently, no problems with flashing.
Please, close this ticket.

Getting the same problem.

I put C:\Program Files\OpenOCD\bin in my path, and nothing happened, so I added C:\Program Files\OpenOCD\share and C:\Program Files\OpenOCD just in case, and still no luck.

echo $path just replies with $path but echo %path% shows all three directories in my PATH variable.

If I type openocd --version into cmd, I get the version information, so I know the path is correct.

I also tried cmd as regular user and admin, and no difference.

Any ideas?

Hi @glenn-andrews ,
This issue is already closed thanks to proper definition of PATH environment variable.
It seems your PATH variable is correct, so it is probably a different issue ...
so it is better you open a new issue with your own description, your own setup and your own error log ...

[glenn-andrews]

My apologies. I'll do so now
