about NRF52832 spi read and write

[tangyu]

Hi,

   I am using NRF52832 for development without bluetooth SDK, NFC and RTC.

   I am using a development board with SPI and a slave device that can communicate normally (using easy dma).

   SCK---p0.29  MOSI---p0.31  MISO---p0.30  CS---p0.6.

   Later we made a circuit board, SPI wiring was changed, the program was not changed, but the interface setting of SPI was changed.

   SCK---p0.0  MOSI---p0.2  MISO---p0.1  CS---p0.12.

    But his communication is not normal, Spi lead pin has been changed.No changes have been made to the program except for the spi pin number setting.Do i need additional configuration when using p0.0 p0.1 as the peripheral IO?I used nrf5_sdk_15.2.0_9412b96

Thanks

In what way(s), exactly, is it "not normal" ?

Have you checked the Product Specification to see if there are any specific requirements or limitations on amy of those those pins ... ?

嗨，

    执行读写操作时，SPI无法正确读写。

     数据手册中未发现使用限制。

     SPI的读/写将被卡在读/写中，这意味着它无法访问读/写完成中断。

So have you used an oscilloscope to see what's actually happening?

What happens if you try these pins on your "development board"   ?

Hi

    I measured the current circuit board SPI signal.CLK CS signal is normal.The MISO and MOSI signals are just a high level and then a low level, no waveform of data is generated.

So what have you done to investigate why that might be happening?
