JLink debug

[medovarsky]

Hi,

After some time not using JLink, I am unable to run JLink as debugger anymore, using debug_tool = custom as documented according to platformio.ini instructions on the documentation page.

On the contrary, I am currently able to debug and upload to STM32L073Z-EVAL board using JLink with extra_script.py as described in issue #1029, using PlatformIO version 3.5.0a13 and VSCode.

My vote for adding JLink as a standard driver.

Do you see any errors? Could you provide your platformio.ini?

platformio.ini:

Could we close this issue?

Yes, please close. Still, JLink does not work.
