spi_transceive (nrf9160) vs nrf_drv_spi_transfer (nrf52)

[paul_tanner]

I have a legacy SPI device that works well with an nrf52 application using nrf_dev_spi_transfer()

I want to use the same device from an nrf9160 application.

The problem arises in multi-byte SPI transfers where differences in the SPI protocol mean that spi_transceive() only achieves single-byte transfers.

Is there a way to configure SPI for the nrf9160 to make it compatible?  In other words, can nrf_dev_spi_transfer() be emulated in the zephyr environment?

Hello,

can you do a logic trace from both the nrf52 and nrf91 SPI transfer? I want to see if there is a difference in the delay between the two cases.
