Using the ST-LINK debugger with 3V3 external power supply
Dear all,
I’m working on the development of a new prototype using the NUCLEO F303RE platform.
I need to power it by using an external 3.3V power supply, but I still want to program and debug it by using the integrated ST-LINK.
If using an external 3V3 power supply, the datasheet indicates that the following jumpers must be removed:
- SB2 (3V3 regulator)
- SB12 (NRST)
The problem is that if we remove SB12, I can’t use the integrated ST-LINK (the NRST signal is unconnected!).
This is the question:
__Is it possible to use the NUCLEO F303RE platform powered by an external 3V3 voltage (SB2 OFF), but programming it with the embedded ST-LINK (SB12 ON)?
__
Thanks in advance
Flavio
