SF32LB56 SPI2用DMA，开机会出现小概率DMA一直timeout，重启后就又可以了。

贾进 · October 16, 2025, 8:04am

1、spi2 DMA配置如下：

#define SPI2_DMA_RX_IRQHandler DMAC1_CH5_IRQHandler
#define SPI2_RX_DMA_IRQ_PRIO 0
#define SPI2_RX_DMA_INSTANCE DMA1_Channel5
#define SPI2_RX_DMA_IRQ DMAC1_CH5_IRQn
#define SPI2_DMA_TX_IRQHandler DMAC1_CH8_IRQHandler
#define SPI2_TX_DMA_IRQ_PRIO 0
#define SPI2_TX_DMA_INSTANCE DMA1_Channel8
#define SPI2_TX_DMA_IRQ DMAC1_CH8_IRQn

2、软件开机配置：

rt_device_t spi_bus = rt_device_find(SPI_BUS_NAME);

if (spi_bus)

{

    rt_device_open(spi_bus, RT_DEVICE_FLAG_RDWR);

    LOG_D("Find spi bus %s:%x\\n", SPI_BUS_NAME, spi_bus);

    spi_dev_handle = (struct rt_spi_device \*)rt_device_find(ADC_DEVICE_NAME);

    if (spi_dev_handle == NULL)

    {

        rst = rt_hw_spi_device_attach(SPI_BUS_NAME, ADC_DEVICE_NAME);

        spi_dev_handle = (struct rt_spi_device \*)rt_device_find(ADC_DEVICE_NAME);

        if (spi_dev_handle == NULL)

        {

            LOG_E("Register spi_dev spi device fail\\n");

            return -RT_ERROR;

        }

    }

    rst = rt_device_open((rt_device_t)(spi_dev_handle), RT_DEVICE_FLAG_RDWR|RT_DEVICE_FLAG_DMA_RX|RT_DEVICE_FLAG_DMA_TX); //RT_DEVICE_FLAG_INT_RX  RT_DEVICE_FLAG_DMA_RX



    spi_dev_cfg.data_width = 16; //bit

    spi_dev_cfg.max_hz = ADC_SAMPLE_SPEED; // hz

    spi_dev_cfg.mode = RT_SPI_MODE_3 | RT_SPI_MSB | RT_SPI_MASTER;

    spi_dev_cfg.frameMode = RT_SPI_TI;//RT_SPI_MOTO; //RT_SPI_TI;

    rst = rt_spi_configure(spi_dev_handle, &spi_dev_cfg);

    LOG_D("rt_spi_configure result:%d", rst);

}

3、读取数据：

rt_spi_transfer((struct rt_spi_device *)spi_dev_handle,ping_buffer, ping_buffer, ADC_BUFFER_SIZE);

会发现概率性的，某次开机一直无法读到数据，一直是DMA timeout。板子重启就又可以了。

小概率出现并且稳定失败的话，怀疑是模块的配置出现问题。建议对比一下正常工作时和出错时DMA与SPI的寄存器配置。

感谢回复，有没有串口打印DMA寄存器的demo接口？

发现异常情况：

spi2 的STATUS:0x78142 正常情况 STATUS:0x78141，对照规格书：

[1] r 1’h0 CSS ClockSynchronizationStatus 0: SPIcontrollerisreadyforslaveclockoperations 1: SPIcontrolleriscurrentlybusysynchronizingslavemode signals [0] r 1’h0 BSY SPIcontrollerBusy 0: SPIcontrollerisidleordisabled 1:SPIcontrolleriscurrentlytransmittingorreceivingframed data

spi 在同步从模式。不明白怎么进入这个模式的。

另外数据寄存器也发现异常，正常是16bit的数据，这里DATA:0x32e94f3f ，明显不正常。

daisangebiao · October 17, 2025, 8:37am

看起来TOP_CTRL寄存器中的bit[2:1] FRF是1, 是ti ssp格式，确认下，这个是想要的设置吗

贾进 · October 17, 2025, 9:53am

是的，这这个模式，另外我试过MOTO模式也同样出现过。

我用56的开发板，问题也会复现。

此外发现一个现象：下载程序第一次开机，出现的概率有点大。

反复上电测试，大概20次左右会出现一次。

daisangebiao · October 17, 2025, 11:06am

麻烦确认下这个bit的现象：这个bit 每次出现timeout后这个bit是否都是1 ？在timeout后读多次是否一直为1？另外出现问题后也dump一下hpsys_rcc的寄存器。

贾进 · October 17, 2025, 11:18am

每次出现都是这个bit为1，下周一我来dump。

此外我测量电平信号，不正常的时候clk一直低，cs一直高

发现

fc 7, xtal 2000, pll 1678 这个有差异；

我每次重启看着两个参数是基本每次都不一样的，是在校准晶振吗？

pengwei · October 20, 2025, 3:28am

pll这个应该没影响。你能提供一个工程或者bin文件我们复现一下吗。另外看配置SPI DMA是CH5和CH8，但是CH7的寄存器为什么也有SPI对应的配置，是不是配错了。

贾进 · October 20, 2025, 3:51am

下午我整理一个可以复现的最小工程。

另外看配置SPI DMA是CH5和CH8，但是CH7的寄存器为什么也有SPI对应的配置，是不是配错了。

这里是我后来改了配置，把SPI的DMA配置到的通道7和8；

可复现问题 bin如附件；

贾进 · October 20, 2025, 8:46am

整理最小系统时候发现问题：

我们这里同时用了SPI1 和SPI2；如果去掉SPI1的配置就不会复现。

麻烦帮忙分析一下具体原因；

最小系统如附件；可替换sifli-sdk\example\hal\spi\src\main.c 验证；

如果出差打印：

10-20 16:39:39:266 [E/drv.spi] spi sem timeout!
10-20 16:39:39:268 [E/drv.spi] spi transfer errorB : 3, errcode=0

10-20 16:39:39:272 [I/DBG] DMA ERROR 0

用你们的开发板，连接串口，反复按reset键可以复现问题

main.c (8.0 KB)

。

Baker221 · October 21, 2025, 10:28am

您好，这边用你提供的bin文件烧录后，通过工具查看DMA相关寄存器发现和描述并不符合，描述中打开的是通道7和通道8，实际寄存器中只发现通道1和通道2有值，且CPAR和CM0AR都是0，像是没有工作的样子，没有启用SPI DMA。另外尝试将main.c放入\example\hal\spi\src\main.c下编译，出现有报错情况，可以提供实际的复现工程吗

贾进 · October 21, 2025, 10:46am

bin下载后，开机，需要按一下power键才进入spi dma模式。

main文件编译，需要开spi2的tx rx DMA。

具体变异错误是什么？

贾进 · October 24, 2025, 3:56am

请问，此问题还有在跟踪吗？

daisangebiao · October 24, 2025, 6:06am

已经可以复现你说的现象，还在找原因。麻烦再等等

daisangebiao · October 27, 2025, 8:40am

这边编不了你给的main函数。可以尝试下在spi2_init里面运行两遍rt_spi_configure，就是把这句话跑两遍：“rst = rt_spi_configure(spi_dev_handle, &spi_dev_cfg);”，看看是否还会出现问题

贾进 · October 27, 2025, 8:57am

编译不了，是什么错误吗？是不是需要配置SPI2的DMA？

好的，我验证后回复你。
