Hi
I am facing an issue by following modifying device tree. i create the file .overlay of type config in in my project directory .i created the folder by following the above instruction.

i just want to use the LED 2 for PWM0. and want to achieve though overlay file. I try both the method one by one by status label to okay in overlay file and 2nd time in nrf9160_common .but the did not change the LED2. please suggest me solution? Do i need to make changes in CMakeLists.txt file too?

Please note, if using nRF Connect SDK v1.6.1, need to add the following lines to Kconfig.zephyr in order for the light intensity controller to build.

config DEPRECATED_ZEPHYR_INT_TYPES
bool "Allow the use of the deprecated zephyr integer types"
help
Allows the use of the deprecated Zephyr integer typedefs defined in
Zephyr 2.3 and previous versions. These types are:
u8_t, u16_t, u32_t, u64_t, s8_t, s16_t, s32_t, and s64_t.

using Zephyr RTOS and segger Embedded studio to develep nrf5340 project , only in code Enable SPIM , not configure SPIM in prj.conf and not bind SPIM in .dts ,does project can work correctly?

I use Zephyr RTOS and segger Embedded studio to develep nrf5340 project. in a c file , i configurate spim2_ns below:

#define SPIM2_CS NRF_GPIO_PIN_MAP(0,15)
#define  SPIM2_SDO NRF_GPIO_PIN_MAP(0,18)
#define  SPIM2_CLK NRF_GPIO_PIN_MAP(0,12)
#define  SPIM2_SDI NRF_GPIO_PIN_MAP(0,14)

static void ADS129x_GPIO_Init(void){

nrf_gpio_cfg_output(SPIM2_CS);

nrf_gpio_pin_set(SPIM2_CS);

}

static void ADS129x_SPIInit(void){

nrf_spim_pins_set(NRF_SPIM2_NS, SPIM2_CLK, SPIM2_SDO, SPIM2_SDI);
nrf_spim_frequency_set(NRF_SPIM2_NS, NRF_SPIM_FREQ_1M);
nrf_spim_configure(NRF_SPIM2_NS, NRF_SPIM_MODE_1, NRF_SPIM_BIT_ORDER_MSB_FIRST);
nrf_spim_enable(NRF_SPIM2_NS);
}

In project file prj.conf, configration has not code about SPI, below code is project's prj.conf

project can build with no error ,

if i select nrf5340dk_cpuappns to build this project , does module SPIM2_NS can work correctly to read/write a SD card?

It seems to me that the project needs to be re-opened for changes to take effect in the multiplication example as well. Great tutorial btw!
