Hi, guys, anyone has met such an issue?

I was trying to generate code by CubeMX, and I also wanna generate USART1 IRQ handler but failed.

here are my settings, anyone can help me with this?

Are you looking at the correct file where it gets generated?

the IRQ handler should be at main.c ?

Umm, no. It's in stm32l4xx_it.c file.

But you shouldn't need to do anything in that file anyways. All your coding would be done in the callbacks which are in stm32l4xx_hal_uart.c or stm32l4xx_hal_uart_ex.c. You just override the weak callbacks that you want to use.
