A small question about the example sketches (e.g. Storage_test, UART_test, Printf)

see this.The UART_test have one initialize for uartA,it just doesnot work,so one delay can fix it.For other examples,some have the initialize for uartA and have enough time to do initialize,like AHRS_test.The Storang_test maybe do not have the initialize.
BTW,this is my pull.:joy: I am first try to make contributions and … I can’t believe they’re so efficient.
