STM32H503EBY uart bootloader

Hello! The AN2606 manual does not describe which pins of STM32H503EBY UART1 uses.

STM32H503EBY have WLCS25 package, but i found information only for others packages

On SO8, WLCSP18, TSSOP20, and UFQFN28 packages USART1 PA9/PA10 IOs are
remapped on PA11/PA12.

Could you tell me which pins shoud be use with WLCS25 ?

Hello @unknown

On this package, you should use the USART2 on pins PA15 and PA5.

Best Regards.
