yes, the version of sdk you got is old, You better get the latest version of the code

Thanks for the reminder... Indeed my branch is outdated :-(

I checked the upstream code by Bouffalo Lab, it looks different...

https://github.com/bouffalolab/bl_iot_sdk/blob/master/components/hal_drv/bl602_hal/hal_spi.c#L334-L342

    if (NULL != RxData) {
        DMA_LLI_Init(arg->rx_dma_ch, &rxllicfg);
        DMA_LLI_Update(arg->rx_dma_ch,(uint32_t)prxlli);
        DMA_Channel_Enable(arg->rx_dma_ch);
    }

    DMA_LLI_Init(arg->tx_dma_ch, &txllicfg);
    DMA_LLI_Update(arg->tx_dma_ch,(uint32_t)ptxlli);
    DMA_Channel_Enable(arg->tx_dma_ch);

Since I'm pulling updates from pine64/bl_iot_sdk, could you kindly ask the Pine64 maintainers to pull the updates from bouffalolab/bl_iot_sdk?

Once Pine64 has updated their repo, I'll run the SPI regression test on PineDio Stack BL604. (Probably using the onboard SPI LoRa SX1262 module)

Also could you explain this wifi_ram section? Thanks! :-)
