Hello,

I updated AC6 framework to the last compiler + openOCD.
I can’t connect anymore to my stm32l476 based board. (Modifying stm32l4.cfg reset configuration is no longer working)

It seems the reset configuration is forced elsewhere:
srst_only separate srst_nogate srst_open_drain connect_assert_srst

here is the complete openocd log.

Please help, I’m stuck in a rut !!
Thanks for your help,
