int32_t main (void)
{
// extern uint32_t SystemFrequency;
STR_UART_T sParam;
UNLOCKREG();
/* Ñ¡ÔñÄÚ²¿22MʼÖÕ*/
DrvSYS_SetOscCtrl(E_SYS_OSC22M, 1);
// DrvSYS_GetPLLContent();

sParam.u32BaudRate = 9600;
sParam.u8cDataBits = DRVUART_DATABITS_8;
sParam.u8cStopBits = DRVUART_STOPBITS_1;
sParam.u8cParity = DRVUART_PARITY_NONE;

// outp32(&SYSCLK->APBCLK, 0x08010000);
while(1)
{
printf("nihao\r\n");
//Delay(10000);
}
}
然后一直卡死在 while(UART1->FSR.TX_FULL == 1); 求助，，， |
