nRF5 SDK 17.1.0 systeminit for nRF52840 and TRACE data

kchuva

Hello Support Team!

I use nRF52840 and migrate to nRF5 SDK 17.1.0. But I can't use Trace functionality, because SystemInit method from system_nrf52.c file use wrong pins - not for nRF52840. And system_nrf52840.c include system_nrf52.c.

/* Enable Trace functionality. If ENABLE_TRACE is not defined, TRACE pins will be used as GPIOs (see Product
   Specification to see which ones). */
#if defined (ENABLE_TRACE) && defined(CLOCK_TRACECONFIG_TRACEMUX_Pos)
    CoreDebug->DEMCR |= CoreDebug_DEMCR_TRCENA_Msk;
    NRF_CLOCK->TRACECONFIG |= CLOCK_TRACECONFIG_TRACEMUX_Parallel << CLOCK_TRACECONFIG_TRACEMUX_Pos;
    NRF_P0->PIN_CNF[14] = (GPIO_PIN_CNF_DRIVE_H0H1 << GPIO_PIN_CNF_DRIVE_Pos) | (GPIO_PIN_CNF_INPUT_Connect << GPIO_PIN_CNF_INPUT_Pos) | (GPIO_PIN_CNF_DIR_Output << GPIO_PIN_CNF_DIR_Pos);
    NRF_P0->PIN_CNF[15] = (GPIO_PIN_CNF_DRIVE_H0H1 << GPIO_PIN_CNF_DRIVE_Pos) | (GPIO_PIN_CNF_INPUT_Connect << GPIO_PIN_CNF_INPUT_Pos) | (GPIO_PIN_CNF_DIR_Output << GPIO_PIN_CNF_DIR_Pos);
    NRF_P0->PIN_CNF[16] = (GPIO_PIN_CNF_DRIVE_H0H1 << GPIO_PIN_CNF_DRIVE_Pos) | (GPIO_PIN_CNF_INPUT_Connect << GPIO_PIN_CNF_INPUT_Pos) | (GPIO_PIN_CNF_DIR_Output << GPIO_PIN_CNF_DIR_Pos);
    NRF_P0->PIN_CNF[18] = (GPIO_PIN_CNF_DRIVE_H0H1 << GPIO_PIN_CNF_DRIVE_Pos) | (GPIO_PIN_CNF_INPUT_Connect << GPIO_PIN_CNF_INPUT_Pos) | (GPIO_PIN_CNF_DIR_Output << GPIO_PIN_CNF_DIR_Pos);
    NRF_P0->PIN_CNF[20] = (GPIO_PIN_CNF_DRIVE_H0H1 << GPIO_PIN_CNF_DRIVE_Pos) | (GPIO_PIN_CNF_INPUT_Connect << GPIO_PIN_CNF_INPUT_Pos) | (GPIO_PIN_CNF_DIR_Output << GPIO_PIN_CNF_DIR_Pos);
#endif

May be I include wrong files?

Please help me.

Best regards,

Konstantin
