Hi!

I have a firmware that works only after Nucleo flashing (using System Workbench). After the flashing if I disconnect, and reconnect microUsb of Nucleo, the program doesn't work anymore. This is not the first time that this happen. What kind of problem could be?

This happen only in Nucleo with Hardware Version: C-02

With C-03 it's ok.

Nucleo Board: Nucleo L152RE

I have updated the STLink Driver.

After flashing, If I press reset button the app works correctly.

If I drag and drop the .bin file in Nucleo folder, it's the same: the app works only the first time, if I remove and reconnect microusb it doesn't work anymore

Hi carbone.fabio,

It seems you are booting from RAM. Connect the BOOT0 pin to GND to boot from flash.
