#define UART2_PADS \
// PAD_ENTRY(MII1_CRS, (MODE(6) | PULLUDEN | RXACTIVE)) /* UART2_RXD */ \
// PAD_ENTRY(MII1_RXERR, (MODE(6) | PULLUDEN)) /* UART2_TXD */ \
PAD_ENTRY(UART0_CTSN, (MODE(1) | PULLUP_EN | RXACTIVE)) /* UART0_RXD */ \
PAD_ENTRY(UART0_RTSN, (MODE(1) | PULLUDEN)) /* UART0_TXD */
然后main.c 也加了
OUTREG32(OALPAtoUA(0x44E10968), (0x1|(1<<5)|(1<<4))); /* GMII_SEL */
OUTREG32(OALPAtoUA(0x44E1096c), (0x1)); /* GMII_SEL */
电平仍然是高
注册表串口3，串口5都打开了测试一样结果
