ST-LINK connection issue with VSCode

[jiangkoumo]

编译正常，也能识别到stlink，但是没办法运行调试烧录，也没办法升级stlink固件 ，一烧录就显示以下报错，目前没找到解决办法，但网上已有与我相同问题的用户

Translationn:

The compilation is normal and stlink can be recognized, but I can't run the debug burn, nor can I upgrade the stlink firmware. The following error is displayed when burning. I haven't found a solution yet, but there are users with the same problem as me on the Internet

Welcome @jiangkoumo, to the (English speaking) community!

What type of ST-LINK are you using?

Could you please include a photo of it, and if it is in a plastic case, please include a photo of the back as well?

Regards
/Peter

是自己设计的板子上板载的stlink，用的f103cbt6芯片做的，使用的stlink-v2的固件

Hi @jiangkoumo 

your ST-link FW may be not updated, please proceed to update and check again (hover on the connected board to get the update button)

您的 ST-link FW 可能未更新，请继续更新并再次检查（将鼠标悬停在连接的板上以获取更新按钮）

seems your board is not connected or well powered please check from this side 

If it is already the case sometime the ST-link FW needs a power cycle to work so I invite you to unplug and re-plug your board

 

似乎您的板子未连接或电源不足，请从这一侧检查。 如果已经是这种情况，有时ST-link固件需要重启才能工作，所以我建议您拔掉并重新插入您的板子。

If this is your own board and you want to build your own ST-LINK/V2 with an STM32F103, it CAN'T work with the software from STMicroelectronics. The ST-LINK firmware is subject to copyright, not released or available for self-built ST-LINKs, copies of this firmware are illegal and are understandably not supported.

STLINK-V3MODS are available for just such applications, which you can solder onto your own board. At least then you are not using illegally copied software.
