Thanks but the problem seems to be with the sd card, multiple sector write consuming more current. I don't think that is anything to do with nordic. That's why not posting about sd card issue.

Then I suggest you open up a new ticket for that issue where you give us as much information as possible, as the current post is about SPI configuration and it being sufficiently answered :)

I'm having some power consumption issues while accessing the SD Card through the SPI lines. So just making sure everything is intact with SPI connection in hardware and firmware

Yes, use nrf_gpio_cfg to set the configuration of a gpio. Why do you need pull resistors for SPI btw?

hi thanks

Does that mean I can set the pull resistors by GPIO ?

See the reset values of the SPIM's Registers. Pull resistors are controlled by the GPIO peripheral and they are unconnected by default.
