Hi I'm using a STM32G030F6. I cant find how to remap the IO ports to the pins: example: Pin1= PB7 /PB8 ? Pin20= PB3/PB4/PB5/PB6 ? register SYSCFG_CFGR1 only selects PA9/PA11 && PA10/PA12 thanks Yona

You can't remap the pins, they are simply connected together internally.

so under what port do I manage pin1 ? PB7 or PB8

Consider them as two/four pins soldered together. Never set more than one of them as output. Set the "unused" ones to analog mode in GPIOB->MODER. This is the default setting after reset, so just leaving the MODER bits alone is fine.

seems strange.( I would have designed it with a remap configuration.)

thanks for the clarification

The product manager would complain loudly, because then they couldn't use the same silicon for different packages.
