I'm unable to reproduce your error. Using SDK 16, I can add __disable_irq(); fine.

Multiple ways, easiest is by turning optimization off at compiler level. If you google "How to disable optimization for specific function", you'll see various examples.

HI，Ivan：

example：BLE_APP_MOUSE

SDK16

one more another question：the source code as below,the "for"statement would be optimised,how to prevent it?

void sensor_init(void)
{
    uint32_t VAR1;
    uint32_t VAR2;
    
    nrf_gpio_cfg_output(power);
    nrf_gpio_cfg_output(cs);
    nrf_gpio_pin_set(cs);
 //   nrf_gpio_pin_set(power);
    nrf_gpio_pin_clear(cs);


   nrf_gpio_pin_set(cs);
   for(VAR1=0;VAR1<10000;VAR1++)
   {
      
   }
   nrf_gpio_pin_clear(cs);

Are you using an example? If so, which one? It should automatically be included through the cmsis_gcc.h header file.

Hi,Ivan:

yes! I have written the function __disable_irq() in my source code,but the compiler Can't find the function.I search the whole solution files.I also can't find it.
