Resolved! X-NUCLEO-BNRG2A1: how to set EXTI on PB14 instead of PA0?
Table 4 of UM2667 says: PA0_SPI_IRQ_PB14_BNRG1BOOT: Default STM32 port = PA0Optional STM32 port = PB14To use the optional port, mount R82 and unmount R85However, on my X-NUCLEO-BNRG2A1, both R82 and R85 are mounted. What should I do?
