[SOLVED] SB9 ST-LINK RESET

Post by FRANCISCOGIMENO » Fri Nov 17, 2017 8:46 am

Hi friends I have a question, when you feed the circuit by the + 5v pin it does not start.

After feeding with 5v, if I connect the usb starts and the program runs, if I remove the usb it stops again.

I have seen that the "SB9 ST-LINK RESET" bridge must be removed when it is powered with 5v.

Can someone tell me if this is correct?
And when removing this bridge I can continue programming from the usb?

a greeting
Fran

Hello friends, after several tests, confirm that if the module is used
With external current supply (+ 5V) that bridge (sb9) must be removed.
