求助，K230的SPI通信连接失败

我使用两个K230，意象建立SPI通信，但是目前一个发送成功，但是另外一边没有接收到
1.我使用的代码，和历程的SPI一致，只是包装成了接口函数

2.两个可执行文件初始化一致

    SPI_Config cfg = {.mode = 0, .cs_pin = 0, .speed_hz = 10000000};
    if (!SPI::Init("spi0", &cfg)) {
        printf("SPI init failed!\n");
        return -1;
    }

3.发送端的部分代码：

        const char* tx_buf = "333666"; 
        size_t length = 6;            
        
        if (SPI_Write(tx_buf, length) < 0) {
            printf("SPI_Write failed!\n");
            return -1;
        }

4.接收端的部分代码：

        uint8_t rx_buf[6] = {0}; 
        size_t length = 6;       
        
        if (SPI_Read(rx_buf, length) < 0) {
            printf("SPI_Read failed!\n");
            return -1;
        }
        
        printf("Received: ");
        for (int i = 0; i < length; i++) {
            printf("%02X ", rx_buf[i]);
        }
        printf("\n");

5.接收端调试信息一直显示00 00 00 00 00 00
发送端一直发送

6.除了代码外，我还怀疑是dts文件配置IO口可能不是SPI，但是我不清楚这个怎么配置

7.平台是01Studio，用的是RTOS的SDK，RT-Smart
连线按照其图纸：

连接SPI0的MOSI、MISO、CS0、SCLK,互相连接

求助大佬帮忙解答！

而且我看你的应用，其中一个230应该做spi从机，但是230的驱动目前是不支持spi从机的。

K230不支持主从配置呀，那建议使用什么进行快速通信呢，感谢大佬解答

用串口吧……

xelll•

也可以用usb

你好，可以参考https://www.kendryte.com/k230_rtos/zh/main/api_reference/peripheral/spi.html 这个需要拉最新的sdk
