STLink can not connect to Nucleo as ''Wrong device detected''

Hello,

I am a new for STM32.

I bought Nucreo-L053R8 board, and installed latest Systemworkbench and STLink USB driver stsw-link009 on my PC. My OS is windows 8.1. I made a very short program and it could be compiled.

When I connect Nucreo board to my PC, I can see it as 'USB BUS DEVICE-STM32 STLink'.

Then I did run on Systemworkbench, then a window is opend and said 'OpenOCD Problem Occured, Reason: Wrong device detedted'.

After few second, USB is disconnected and I can see it as unknown device.

When I made the project, I select the device as L053.

Console shows like following.

Maybe wrong configuration - you have ST-LINK v2 but you actually has v-1 in cfg file.

stlink-v2.cfg:

VID/PID 0x0483 0x3748 for ST-Link/V2

VID/PID 0x0483 0x374b for ST-Link/V2-1

Bogdan,

Thank you for your reply.

I changed the config file as ST-Link/v2, and the error massage of 

'

Info : vid/pid are not identical: 0x0483/0x374B 0x0483/0x3748'

is disappered. but the result is still same.

My board usb hardware infomation's PID is 0x3748, so my board is ST-Link/v2 for sure. 

And I noticed that, the log said,

'

Info : STLINK v2 JTAG v25 API v2 SWIM v14 VID 0x0483 PID 0x3748'

so it will connect as SWIM, but my project debug config has 

 'transport select 'hla_swd'

that mean I think the config setting is SWD but the hardware is SWIM.

If this is the problem, how can I change the config from SWD to SWIM? I tried to change the hla_swd to hla_swim, but when I build it, the swim character is change to swd automatically.

Dear Takayoshi Ishii,

You said 'that mean I think the config setting is SWD but the hardware is SWIM.',

but ALL STLink/V2-1 in Nucleo uses SWD interface despite supporting JTAG/SWD/SWIM.

Currently OpenOCD cfg's default SWD clock settings for L0 is too fast,

so you need to reduce clock below 1000kHz.

I met same problem STM32L053C8-Discovery,and avoid the error to reduce SWD clock.

See my article for more information.
