Hi everyone, I need some help with ST-LINK/V2.

EntwicklerJVI · ‎2020-03-25

I am using this ST-LINK/V2 for programming bluetooth chip BGM11S through SWD.

This bluetooth chip has SWD-pins for communication.

But ST-LINK/V2 can not connect with this bluetooth chip, there is an error: "Unknown or unsupported device (DevID = 0x0000)".

The screenshot is under, do you guys have any idea about this? Thank you very much from Germany.

The St Software obvious does not work with none-St chips. You can use the StlinkV2 with pyocd, openocd or bl*ackm*g*c with the pc-stlinkv2 platform.

B.t.w. to my knowledge, StlinkV3 actively denies cooperation with non-ST parts. An it is more picky to connect to ST parts.

The problem is the toolchain, and it's support of debug pods.

Segger has a JLink firmware for ST-Links, available for free download. That should work with other toolchains and MCUs as well.

Hi Uwe, hi Ozone. Thank you for your replies.

@Ozone Which JLink firmware do you mean? I have tried with JLink Commander, but it does not work. Thank you in advance.

No - Segger used to have a firmware for the ST-Link pod, that "converted" the ST-Link into a JLink.

Alternatively to the ST-Link firmware.

The advantage is the JLink support by toolchains - and Segger tools.
