Not sure what you talking about.

The ST-Link adapter, sold separately by ST, is actually a SWD/JTAG + SWIM adapter. The SWIM interface is for STM7/STM8 controllers. The integrated ST-Link, which comes with discovery boards, is SWD only. It should not support SWIM. Could you possibly have ''updated'' it to a wrong firmware ? Have you checked the ST webpage for updates for both the ST-Link Utility and ST-Link firmware ?

http://yadi.sk/d/OfqyzOAv229la - st-link-upgrade On the St-Link-utility when i press ''Connect'' button i see ''STLink USB communication error'' But when i remove STM32L-Discovery board from USB i see  No STLink detected. So i think than board is a live I have all updated from official site www.st.com - not working. I try to use differen version of ''STLinkUSBDriver.dll'' from other IDE by KEIL and ARM

http://yadi.sk/d/OfqyzOAv229la - st-link-upgrade I don't know that sites, and how old this 'updates' are. What about this instead:

http://www.st.com/internet/evalboard/product/251168.jsp

Current version is 2.16.4.On the St-Link-utility when i press ''Connect'' button i see ''STLink USB communication error'' But when i remove STM32L-Discovery board from USB i see  No STLink detected. So i think than board is a live I don't think so. If it says ''STLink USB communication error'', it can't even communicate correctly with the ST-Link part. It may be alive, but there is something wrong. Have you consulted the Windoze HardwareManager ?I try to use differen version of ''STLinkUSBDriver.dll'' from other IDE by KEIL and ARM There is also a Windows USB driver, by the way. Do you have another discovery board, or can you check you board on another PC ?

This is README -

Did you try this with the latest ''ST-Link Utility'' software ?

I have exercised this here with a F0 discovery. Upon startup, the ST-Link Utility told me:  08:33:34 : Old ST-LINK firmware detected!              Please upgrade it from ST-LINK->'Firmware update' menu.   08:33:34 : Connected via SWD. I did that, and ''ST-Link->Firmware update'' told me:    Firmware Version : V2.J14.S0 JTAG Debugger     Upgrade the firmware to V2.J16.S0 Did you change some jumper settings on the board ? I never came across such issues. Edit: I get the same result as you when I try to update a STM8 discovery, which actually uses SWIM. Not sure what you are doing.

Posted on February 21, 2013 at 14:39I have the same problem with my STM32L DISCOVERY. On-board  STLink programmer still not working.ST-Link Upgrade Utility detect my  board as V2.J0.S4 SWIM Debugger. When I try to connect a target or to change settings I get an error: ''STLink USB Communication error'' . All drivers and utilities have latest version. How can solve this problem?

Based on the discussion so far I'm not sure it's recoverable.

You could perhaps try to roll it back to a prior firmware?

I just updated STLink firmware by the STLink Upgrade Utility because it asked me about it...

Is it possible to roll it back to a prior firmware?I have anoter STLink programmer.

Yesterday I tried to read original firmware from another working  STM32 Discovery's STLink.

Of course it was read-protected. In result  of those manipulations I have got blank MCU STM32F103C8T6.Is it possible to find firmware for it?Can anybody help me?
