[OpenOCD-devel] [openocd:tickets] #149 ST-Link Unsupported status code 0x09

[Spencer O. <nt...@us...>]

Just had a scan through some docs that ST sent us ages ago and I have the following error codes listed.

~~~

** [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

**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.
