Hello,
I am working on a QN9080SIP based project.
I bought a QN9080SIP-DK board. I was able to compile/debug on the board.
After I configure hardware (I used MCUXpresso Config Tools) to enable external 32MHz clock and disable internal oscillator. The problem is that the generated code disable OSC32M before enable external clock.
After I upload the compiled code, I am no more able to access the board to download program/debug.
Is there some way I can solve this?
This is the MCUXpresso Config Tools generated code:
void BOARD_BootClockRUN(void)
{
/*!< Power up/Power down the module. */
POWER_EnablePD(kPDRUNCFG_PD_RCO32K); /*!< Power down RCO32K */
POWER_EnablePD(kPDRUNCFG_PD_OSC32M); /*!< Power down OSC32M */
/*!< Set up clock selectors - Attach clocks to the peripheries */
CLOCK_AttachClk(k32M_to_XTAL_CLK); /*!< Switch XTAL_CLK to 32M */
CLOCK_AttachClk(kXTAL32K_to_32K_CLK); /*!< Switch 32K_CLK to XTAL32K */
CLOCK_AttachClk(kXTAL_to_SYS_CLK); /*!< Switch SYS_CLK to XTAL */
CLOCK_AttachClk(kAPB_to_WDT_CLK); /*!< Switch WDT_CLK to APB */
/*!< Set up dividers */
CLOCK_SetClkDiv(kCLOCK_DivXtalClk, 0U); /*!< Set XTAL_DIV divider to value 1 */
CLOCK_SetClkDiv(kCLOCK_DivAhbClk, 0U); /*!< Set AHB_DIV divider to value 1 */
CLOCK_SetClkDiv(kCLOCK_DivFrg1, 0U); /*!< Set FRG_MULT1 to value 0, Set FRG_DIV1 to value 255 */
CLOCK_SetClkDiv(kCLOCK_DivFrg0, 0U); /*!< Set FRG_MULT0 to value 0, Set FRG_DIV0 to value 255 */
CLOCK_SetClkDiv(kCLOCK_DivApbClk, 0U); /*!< Set APB_DIV divider to value 1 */
/*!< Enable/Disable clock out source and pins.*/
/*!< Enable/Disable the specified peripheral clock.*/
}
