Using nRF5340-PDK with zephyr adxl372 sensor sample project

Question

I'm new to the nRF5340 and zephyr and ncs, but I have gone through the tutorial series https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/b/getting-started/posts/nrf-connect-sdk-tutorial 
 We're developing a product that will use the SPIS peripheral on the nRF5340 and I have a few nRF5340-PDK boards 
 Since I haven't found any SPIS sample projects, I started with the zephyr adxl372 sensor sample project. 
 I wanted to get it to a point where the SPIM peripheral was working (wiggling pins as expected) then create my own sensor and change it to SPIS. 
 I re-mapped the SPI pins to pins on port 1. 
 I started by using the non-secure build, but couldn't get any SPI activity on the pins. 
 It looked like the chip select pin was being handled as a GPIO pin (rather than as part of the SPIM peripheral) and when I tried to manually change registers in the GPIO1 peripheral through the SES through the registers view, all the SPIM1 registers showed as 0 and I couldn't change them. 
 I wondered if GPIO1 was not under the application processor's control, because the NRF_P1 is missing from the peripheral domain status printed at bootup. 
 Peripheral Domain Status 00 NRF_P0 Non-Secure OK 01 NRF_CLOCK Non-Secure OK 02 NRF_RTC0 Non-Secure OK 03 NRF_RTC1 Non-Secure OK 04 NRF_NVMC Non-Secure OK 05 NRF_UARTE1 Non-Secure OK 06 NRF_UARTE2 Secure SKIP 07 NRF_TWIM2 Non-Secure OK 08 NRF_SPIM3 Non-Secure OK 09 NRF_TIMER0 Non-Secure OK 10 NRF_TIMER1 Non-Secure OK 11 NRF_TIMER2 Non-Secure OK 12 NRF_SAADC Non-Secure OK 13 NRF_PWM0 Non-Secure OK 14 NRF_PWM1 Non-Secure OK 15 NRF_PWM2 Non-Secure OK 16 NRF_PWM3 Non-Secure OK 17 NRF_IPC Non-Secure OK 18 NRF_VMC Non-Secure OK 19 NRF_FPU Non-Secure OK 20 NRF_EGU1 Non-Secure OK 21 NRF_EGU2 Non-Secure OK 22 NRF_DPPIC Non-Secure OK 23 NRF_GPIOTE1 Non-Secure OK 24 NRF_REGULATORS Non-Secure OK 
 When I choose Project > Configure nRF Connect SDK Project (in the non-secure project) it shows two options - menuconfig and spm_menuconfig 
 I tried the secure build, and then I saw SPI activity. 
 But when I try to view the configuration with Project > Configure nRF Connect SDK Project (in the secure project) it does not show me two options. It just takes me to a config. 
 
 Q1: Why doesn't the non-secure project work to control the SPI pins? 
 Q2: Why doesn't the secure project show both menuconfig and spm_menuconfig?

I am really sorry for the late reply. I managed to make it work by modifying the files subsys/spm/spm.c and subsys/spm/Kconfig . 
 Could you try to apply the patch below to NCS v1.2.0 (nrf repo) and see if you can make it work. I was able to make it work with the P1 pins with these changes.

Regarding referencing the P1 pins by using the index plus 32, you are correct, it seems like this function will find the correct port. I have not used this approach before, so I apologize for the confusion. I am learning every day
