程序需要使用SPI，再添加SPI初始化后发现程序不运行，在SPI初始化前后各加了打印函数。然后只会打印第一个。
SDITask_PrintfToUART("%s\r\n", "Hello from SPP BLE Server!");
HwSPIInit();
SDITask_PrintfToUART("%s\r\n", "Hello from SPP BLE Server!");
后来发现修改任务栈大小后，可能会一个都不能打印，#define SBP_TASK_STACK_SIZE 1144//644，1044，1344。
1144大小就不能打印了。1044可以打印1个。但是如果不加这个SPI初始化，1344仍可以打印2个，而且会执行到后面的广播，会打印广播信息。这是RAM不够用吗？
在.MAP文件里发现RAM只用了13K。难道程序在运行的过程中，会消耗7k的RAM，SPI消耗的大？麻烦了解的大佬给指点下，是什么原因，我改如何调试？
还有我也不确定是否使用uDMA，我想使用uDMA应该如何配置？

{
// hSPIPins = PIN_open(&SPIPins, SPIPinsCfg); //SPIIO配置，后再主程序开始时配置
SPI_init();
SDITask_PrintfToUART("%s\r\n", "Hello from SPP BLE Server!"); //执行不到此处
SPI_Params_init(&SPIparams);
SPIparams.bitRate = 2000000; //2MHz 32：1.8432MHz
SPIparams.dataSize = 8;
SPIparams.frameFormat = SPI_POL0_PHA1; //相位1极性0
SPIparams.mode = SPI_MASTER; //SPI主从模式
SPIparams.transferMode = SPI_MODE_CALLBACK; //回调模式
SPIparams.transferCallbackFxn = spiSlaveCallback;//回调函数
SPIparams.transferTimeout = SPI_WAIT_FOREVER;
