Custom board with Kinetis MKL03Z MCU

[tomazlov]

I have been able to sucessfully compile simple BLINK program and flash my custom board (Kinetis MKL03Z8VFG4R) with Jlink inside MCUXpresso v10.2.0 using command:

Operation was sucessfull, in console I can see this output:

I can then debug my custom board (I see printed characters from my PRINTF() function in JlLink GDB Server console), but my firmware runs only when in debug session. In source I have set internal LIRC clock (2Mhz) and I have only 1 configuration, ie. BOARD_BootClockRUN(), which I pressume should start CPU in "normal" mode.

Why is my board not starting if I only apply power lines to it? Is it depend on any project options: I used default project options, ie. "SDK Debug Console: Semihost", "Redlib (semihost-nf)", etc.)?

Edit:

I have also tried to set (Quick Settings-->SDB Debug Console) to "UART console" (as suggested in MCUXpresso IDE and Semihosting), but its not working either. My Preprocessor Defined Symbols are as below:

__REDLIB__

CPU_MKL03Z8VFK4

CPU_MKL03Z8VFK4_cm0plus

CR_INTEGER_PRINTF

PRINTF_FLOAT_ENABLE=0

__MCUXPRESSO

__USE_CMSIS

DEBUG

SDK_DEBUGCONSOLE=1

Using MCUXpresso Config Tools I have manually set UART0 line (is this a problem?). I tried even with different combinations of directives (NDEBUG, SDK_DEBUGCONSOLE 1/0), but CPU does not start running. 

My PINs initialization routine is:

void BOARD_InitPins(void)
{
   CLOCK_EnableClock(kCLOCK_PortA);
   CLOCK_EnableClock(kCLOCK_PortB);

   gpio_pin_config_t LED_GREEN_config = {
      .pinDirection = kGPIO_DigitalOutput,
      .outputLogic = 0U
   };

   GPIO_PinInit(BOARD_INITPINS_LED_GREEN_GPIO,    BOARD_INITPINS_LED_GREEN_PIN, &LED_GREEN_config);

   gpio_pin_config_t LED_RED_config = {
      .pinDirection = kGPIO_DigitalOutput,
      .outputLogic = 0U
   };

GPIO_PinInit(BOARD_INITPINS_LED_RED_GPIO, BOARD_INITPINS_LED_RED_PIN, &LED_RED_config);

PORT_SetPinMux(BOARD_INITPINS_LED_GREEN_PORT, BOARD_INITPINS_LED_GREEN_PIN, kPORT_MuxAsGpio);

PORT_SetPinMux(BOARD_INITPINS_LED_RED_PORT, BOARD_INITPINS_LED_RED_PIN, kPORT_MuxAsGpio);

/* PORTB1 (pin 9) is configured as LPUART0_RX */
PORT_SetPinMux(BOARD_INITPINS_UART_RX_PORT, BOARD_INITPINS_UART_RX_PIN, kPORT_MuxAlt3);

/* PORTB2 (pin 10) is configured as LPUART0_TX */
PORT_SetPinMux(BOARD_INITPINS_UART_TX_PORT, BOARD_INITPINS_UART_TX_PIN, kPORT_MuxAlt3);

/* PORTB3 (pin 11) is configured as I2C0_SCL */
PORT_SetPinMux(BOARD_INITPINS_SCL_PORT, BOARD_INITPINS_SCL_PIN, kPORT_MuxAlt2);

/* PORTB4 (pin 12) is configured as I2C0_SDA */
PORT_SetPinMux(BOARD_INITPINS_SDA_PORT, BOARD_INITPINS_SDA_PIN, kPORT_MuxAlt2);

SIM->SOPT5 = ((SIM->SOPT5 &
                     /* Mask bits to zero which are setting */
                     (~(SIM_SOPT5_LPUART0RXSRC_MASK)))

                     /* LPUART0 Receive Data Source Select: LPUART_RX pin. */
                     | SIM_SOPT5_LPUART0RXSRC(SOPT5_LPUART0RXSRC_LPUART_RX));
}

Hi,

Please probe the KL03 RESET pin status without debugger with power up.

And you can just toggle a led to check if your application code works without debugger.

Please let us know the KL03 RESET pin status during power up.

Have a great day,
Mike
