I tried your OUT file, after loading I do not see anything, neither UART port output or USB device driver detection in the Windows.
Looks like to me even the Ext ref Oscillator did not turn ON and that maybe because PTA29 is NOT turned ON in your binary image.
I do this for enabling external clock:
void SystemConfigureClocks(uint32_t clkdiv1, bool enableUsb)
{
// CMSIS CLOCK_SETUP=1
/* SIM->SCGC5: PORTA=1 */
SIM->SCGC5 |= SIM_SCGC5_PORTA_MASK; /* Enable clock gate for ports to enable pin routing */
// /* This is for External CLOCK */
PORT_PCR_REG((PORTA_BASE_PTR), 29) = PORT_PCR_MUX(0x01); // set OSC_EN (PTA29) to be a GPIO function
GPIO_PDOR_REG(PTA_BASE_PTR) |= (uint32_t)0x20000000UL; // set to high
GPIO_PDDR_REG(PTA_BASE_PTR) |= (uint32_t)0x20000000UL; // make it an output
PORT_PCR_REG((PORTA_BASE_PTR), 19) = PORT_PCR_MUX(0x01) | PORT_PCR_DSE_MASK; // VSW_8V0_PWM
