1.帮忙看一下这个代码，用UART4发送数据时，为什么数据只发送一次，就发送不了了，
eg：如下代码执行，只收得到UART HELLO WORD，收不到字符串sssaannnh
char testIdPrompt[24] = "UART HELLO WORD\r\n";
char crPrompt[16] = "sssaannnh\r\n";
UART_write(uart, (void *)(uintptr_t)testIdPrompt, sizeof(testIdPrompt));
//Osal_delay(100);
UART_write(uart, (void *)(uintptr_t)crPrompt, sizeof(crPrompt));
#if 1
/* Define the UART test interface */
typedef struct UART_Tests_s
{bool(*testFunc)(bool);booldmaMode;int16_t testId;chartestDesc[80];
} UART_Tests;
UART_PAR uartParity = UART_PAR_NONE;
uint32_t verifyLoopback = FALSE;
UART_Tests Uart_tests[] =
{{NULL, false, 1, "\r\n UART non-DMA read write test in block mode"},{NULL, }
};
static void UART_initConfig_test(bool dmaMode)
{UART_HwAttrs uart_cfg;/* Get the default UART init configurations */UART_socGetInitCfg(4, &uart_cfg);uart_cfg.edmaHandle = NULL;uart_cfg.dmaMode= FALSE;uart_cfg.loopback= verifyLoopback;/* Set the DMA enabled UART init configurations */UART_socSetInitCfg(4, &uart_cfg);
}
int UART_mcutest_print_test_desc22(UART_Tests *test)
{linData_tlinMasterData;UART_Handle uart = NULL;UART_Params uartParams;chartestIdPrompt[24] = "UART HELLO WORD\r\n";
charcrPrompt[16] = "sssaannnh\r\n";chartestId[16] = {0, };int8_tstatus= 0;uint8_tprotectId= 0;UART_init();appLogPrintf("APP: Init mcu2_1 print_test000 H0 EZHU... !!!\n");/* UART SoC init configuration */UART_initConfig_test(false);//关闭DMAappLogPrintf("APP: Init mcu2_1 print_test111 HEZHU... !!!\n");/* Initialize the default configuration params. */UART_Params_init(&uartParams);uartParams.parityType = uartParity;appLogPrintf("APP: Init mcu2_1 print_test222 HEZHU... !!!\n");uart = UART_open(4, &uartParams);if(uart == NULL){appLogPrintf("\nFailed to get the UART handle\n");return -1;}appLogPrintf("APP: Init mcu2_1 print_test333 HEZHU... !!!\n");/* Print unit test ID */sprintf(testId, "%d", test->testId);UART_write(uart, (void *)(uintptr_t)testIdPrompt, sizeof(testIdPrompt));//Osal_delay(100);UART_write(uart, (void *)(uintptr_t)crPrompt, sizeof(crPrompt));UART_write(uart, (void *)(uintptr_t)testId, sizeof(testId));//UART_write(uart, (void *)(uintptr_t)crPrompt, sizeof(crPrompt));UART_close(uart);return 0;
}

使用的SDK版本是：ti-processor-sdk-rtos-j721e-evm-08_01_00_13
串口使用的参数都是使用的默认参数，请问是否是不是某个参数不对，导致只发送一次的，帮忙看一下。谢谢
希望尽快帮忙查看一下，急！！
