I try to using uart0 as console but I found that there is nothing out from console.
In board.c
sunxi_usart_t usart0_dbg = {
.base = 0x02500000,
.id = 0,
.gpio_tx = {GPIO_PIN(PORTE, 2), GPIO_PERIPH_MUX7},
.gpio_rx = {GPIO_PIN(PORTE, 3), GPIO_PERIPH_MUX7},
};

in t113 datasheet ,uart0 is Function 6
I fix to MUX6 and uart0 works.
