Does it mean you use a board config that lacks "reset_config
srst_only" when in fact this board has SRST properly connected?

** [tickets:#149] ST-Link Unsupported status code 0x09**
**Status:** new
**Milestone:** 0.9.0
**Created:** Fri Mar 31, 2017 11:44 AM UTC by steve
**Last Updated:** Fri Mar 31, 2017 03:10 PM UTC
**Owner:** nobody
Using STM32L031 Nucleo for detailed investigation, although suspect similar problem \
on STM32L050 Nucleo. Running ST-Link software 2J28M18 (latest as of now). OpenOCD \
release 0.10 final Fails to connect to target.
Relevant debug output:
~~~
Debug: 256 47 stlink_usb.c:817 stlink_usb_init_mode(): MODE: 0x01
Debug: 257 47 stlink_usb.c:442 stlink_usb_error_check(): unknown/unexpected STLINK \
status code 0x9
Error: 258 47 stlink_usb.c:1779 stlink_usb_open(): init mode failed (unable to \
connect to the target) ~~~
Looking in the source, this status code does not appear to be recognised at all - \
presumably recent addition.
I tried reducing clock speed from 300kHz to 100kHz without any difference.
Note: I can connect to the target using ST-Link.
