commit 9aa131650862bf060e193a14ed241d95bfb740ad Author: raiden00pl <[email protected]> AuthorDate: Fri Oct 30 12:53:35 2026 +0100 boards/nucleo-l496zg: Enable VDDIO2 for the port G I/Os. PG2-PG15 are supplied by VDDIO2 and stay unpowered until PWR_CR2.IOSV is set, which leaves the LPUART1 console on PG7/PG8 (ST-LINK VCP) dead.
