SPI transfer is not working successfully

[shilpa]

Hello,

I am using SDK 15.2.0, nrf52840, s140.

We are using SPI for an analog Front End initialization. SPI initialization works successfully done. But when we read or write to the registers of the IC  using SPI transfer functions, the transfer is not done successfully.

I have connected the SPI clock pin to the RESET pin of BMD 340 (P0.18) in my custom board. Whether this can cause an issue? I am able to program each pin(MOSI, MISO, CLOCK, CHIPSELECT checked by setting the pin using nrf_gpio_pin_set) .

Regards,

Shilpa

Hi,

Could CONFIG_GPIO_AS_PINRESET resolve the issue?

That is not easy for me to answer, you did not describe the problem much beyond saying it does not work. I suggest you try it and post some screenshots of what happens on the SPI lines.

Hi

I tried it by removing CONFIG_GPIO_AS_PINRESET from configurations. All works well. Thank you so much.
