Hi.

I was just programming my stm32f217 board via serial wire interface and everything was ok, but when I wanted to program once more the message ''No target connected''displayed and it didn't program my MCU anymore.

But when I use IAR to program stm8 it works.

What is the problem?

I tried updating the firmware but the message bellow displayed that I don't know what it is.

I have a new problem. Every time I want to program I have to make Boot0 high, reset, plug out the st link(because IDE don't recognize st-lin k),plug in the st link and at last program.It wasnt like this before.I cant use debug option either.

You need to review what you are doing with the PA13/PA14 pins in your design, or if you are powering off the device.

When 

iuse cubemx

 I mostly tick the 'set all the free pins analog to optimize power consumption' this made the

swdioandswclk

 analog and this was the problem. Thanks.
