Porting App from PCA10056 to PCA10059

Question

Hi to all, 
 i had developed an app for PCA10056 and now i want port it on PCA10059, there is any guide or white paper that indicate how can i done that?? 
 i read in the froum that changing PCA10056 to PCA10059 in preprocessor defines may help but it dose not work for me. 
 
 thanks

Have you based your app on one of the 52840 pca10056 nRF5 SDK examples? If you are using the LED on the 52840 dongle, this could be related to a UICR issue which does not set the GPIO output voltage to 3.0 Volts. See e.g. the gpio_output_voltage_setup() example defined in the ble_app_blinky example pca10056 example from SDK v15.2.0:

#if defined(BOARD_PCA10059)
/**
 * Function for configuring UICR_REGOUT0 register
 * to set GPIO output voltage to 3.0V.
 */
static void gpio_output_voltage_setup(void)
{
    // Configure UICR_REGOUT0 register only if it is set to default value.
    if ((NRF_UICR->REGOUT0 & UICR_REGOUT0_VOUT_Msk) ==
        (UICR_REGOUT0_VOUT_DEFAULT << UICR_REGOUT0_VOUT_Pos))
    {
        NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Wen;
        while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}

        NRF_UICR->REGOUT0 = (NRF_UICR->REGOUT0 & ~((uint32_t)UICR_REGOUT0_VOUT_Msk)) |
                            (UICR_REGOUT0_VOUT_3V0 << UICR_REGOUT0_VOUT_Pos);

        NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Ren;
        while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}

        // System reset is needed to update UICR registers.
        NVIC_SystemReset();
    }
}
#endif

It may also be related to this code in the bsp_board_leds_init():

    #if defined(BOARD_PCA10059)
    // If nRF52 USB Dongle is powered from USB (high voltage mode),
    // GPIO output voltage is set to 1.8 V by default, which is not
    // enough to turn on green and blue LEDs. Therefore, GPIO voltage
    // needs to be increased to 3.0 V by configuring the UICR register.
    if (NRF_POWER->MAINREGSTATUS &
       (POWER_MAINREGSTATUS_MAINREGSTATUS_High << POWER_MAINREGSTATUS_MAINREGSTATUS_Pos))
    {
        gpio_output_voltage_setup();
    }
    #endif

I am assuming you have checked that your app for the 52840 pca10056 DK worked on the 52840 DK before you ported to the 52840 dongle, correct?
