Other Parts Discussed in Thread: CC1310
首先参考这篇文章SimpleLink MCU代码移植指南：CC1310从VQFN48(7×7)到VQFN32(5×5)代码移植流程参考 - 嵌入式处理 - 技术文章 - E2E
设计支持 (ti.com)，将CC1310_LAUNCHXL.h中除了SPI0的IO都赋值PIN_UNASSIGNED。

主函数如下：
void *mainThread(void *arg0)
{
uint16_t buf_num;
for(buf_num = 0 ; buf_num < MASSAGE ; buf_num ++)
{
transmitBuffer[buf_num] = buf_num;
}
SPI_init();
SPI_Params_init(&spiParams); // Initialize SPI parameters
spiParams.transferMode = SPI_MODE_BLOCKING; //
spiParams.dataSize = 8; // 8-bit data size
spiParams.mode = SPI_MASTER; //SPI MASTER
spiParams.frameFormat = SPI_POL0_PHA1; //SPI POL0 PHA0
spiParams.bitRate = 4000000; //4MHZ
spiTransaction.count = MASSAGE;
spiTransaction.txBuf = (void *)transmitBuffer;
spiTransaction.rxBuf = (void *)receiveBuffer;
spi = SPI_open(Board_SPI0, &spiParams);
if (spi == NULL) {
while (1); // SPI_open() failed
}
SPI_transfer(spi,&spiTransaction);
usleep(100);
return (NULL);
}
代码会在跑完SPI_transfer之后跑飞。代码在7X7封装上依然可以运行，但是在4X4上会跑飞。请问还有哪些地方需要修改，才可以正常工作？
