TI中文支持网Part Number:LAUNCHXL-CC1310Other 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_tbuf_num;for(buf_num = 0 ; buf_num < MASSAGE ; buf_num ++){transmitBuffer[buf_num] = buf_num;}SPI_init();SPI_Params_init(&spiParams); // Initialize SPI parametersspiParams.transferMode = SPI_MODE_BLOCKING; //spiParams.dataSize = 8;// 8-bit data sizespiParams.mode = SPI_MASTER; //SPI MASTERspiParams.frameFormat = SPI_POL0_PHA1; //SPI POL0 PHA0spiParams.bitRate = 4000000; //4MHZspiTransaction.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？
Kevin Qiu1：
下面是以前4*4的配置文件，与新的SDK相比有了一些小变化，你可以参考它修改现在的SDK文件
CC1310DK_4XD.zip
除了.c和.h文件外，ccfg和cmd文件也要保持一致

yuan jiadong：
你好，1、现在将spiCC26XXDMAHWAttrs.minDmaTransferSize改为比较大的值，也就是不使用SPIDMA，可以跑过，也有波形输出。但是我本意是想用SPIDMA的，不知道什么原因会导致无法使用。2、还有就是发现使用sleep函数的时候也会跑飞，不是很明白。

Kevin Qiu1：
如果在必须在 7*7的板子上可以正常运行，那么正确移植后也应在4*4的板子上正常执行

RX FIFO 变满之前再次调用SPI_transfer()以避免溢出
对照这里的说明在检查下SPI的使用：https://dev.ti.com/tirex/content/simplelink_cc13x0_sdk_4_20_01_03/docs/tidrivers/doxygen/html/_s_p_i_c_c26_x_x_d_m_a_8h.html

yuan jiadong：
你好，谢谢你的回复。现在我对着配置文件来来回回试了很多次还是不行，然后我单步调试一直跟到后面，发现是在SPI_TRAN之后卡在了SemaphoreP_pend函数中，一直等不到SemaphoreP_post函数释放线程。在SemaphoreP_pend函数中死循环了。但是在7X7中还是可以运行。所以是有什么配置文件会影响到这里吗？

Kevin Qiu1：
你的4*4的内存是否核原来7*7的一致？如果可能不一致则可能是内存不够用了
参考下面的任务2使用ROV看下任务运行核内存使用情况：https://dev.ti.com/tirex/content/simplelink_academy_cc13x0sdk_4_20_00_00/modules/rtos/tirtos_basics/tirtos_basics.html
