Hello,
I made a minimal system board with s32k144. After I finished soldering the component and power the board on (no software flashed), I used an oscilloscope to watch the waveform of PTB6 and PTB7. There is no waveform, solely a constant dc voltage which is about 0.8V high.
Is it normal to have a constant dc voltage at these pins? I thought it should be a sine waveform. Please see the circuit below.
Hi,
I have a custom board using s32k144 and I'm using S32 Design Studio for S32 Platform.
My code stucks in timeout when starting external crystal:
CLOCK_SYS_ConfigureSOSC function:
while ((CLOCK_SYS_GetSysOscFreq() == 0U) && (timeout > 0U))I my processor expert there isn't an option for external crystal:
Thanks.
Hi ZZD,
The sine waveform is not generate by default. You need to initialize system oscillator (SOSC) first.
If Processor Expert is used, you can achieve it by configure SOSC in clock_manager.
Best Regards,
Robin
