Nucleo 32 3.3v bridges

Post by macarion »

Hola,
I'm a bit lost with this board in order to power up with 3.3v, the board it's NUCLEO-G031K8 and Datasheet

As per manual, I remove SB3 and SB2 (SB2 it's default off) solder bridgeS but I'm not able to power up it from 3.3v, the power led it's ON but seems the code it's not running
When the board is powered by +3V3 (CN4 pin 14), solder bridges SB2 (NRST) and SB3 must be OFF.
I also tried to desolder SB11, but now then power light it's also OFF
SB11 OFF: 3.3 V main voltage regulator output disabled (useful when
powering the STM32G0 Nucleo-32 with a 3.3 V applied on
CN4 pin 14)
I'm not sure if I'm doing something wrong, I don't know what else to try, any help is welcome.
