UART dont run

[fmaesso]

Hi, I'm using Maix bit and remaped the uart1 to pins15 and 26. When I test my script with IDE everything run fine sendig data to uart1, but when save it in the board and running stand alone the data is not sent to UART1. What I losted ? Can one help me?

fm.register(15, fm.fpioa.UART1_RX, force=True) fm.register(26, fm.fpioa.UART1_TX, force=True)

uart1 = UART(UART.UART1, 115200, 8, None, 1, timeout=1000, read_buf_len=1024)
