Hi,

I am using the ST link V2 debugger and i have updated the firmware using stm32 programmer software and used the stsw-link009 and when i tried connecting it  shows me some below errors. After updating the firmware it worked for few moments and then  it suddenly stopped.

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

Check Pin 1 or 2 of the 20-pin JTAG Header, the board you're connecting too should present 3.3V, check your ground connections also.

Show the setup here, what's connected to what?
