ADC issue for external channels on S32k146 controller.

Hi,

"ADC conversion not happening for external channels when S32k144 compiled code loaded on S32k146 controller".

I have taken adc_swtrigger_s32k144 example code and configured external input channel 10 to read voltage and is working as expected on S32k144 controller but when the same code is flashed on S32k146 controller not getting expected value.

Is S32k144 compiled code compatible with S32k146 controller?

While debugging observed that ADC conversion is happening but result register RA is showing value as 7 every time. 

Also, I've tried to measure the reference BANDGAP voltage, as per the ref manual result should be 1V but I am getting around 0.6V.

 

Anyone, please suggest the solution.

Hi PawanGupta,

Is S32k144 compiled code compatible with S32k146 controller?
No.
Why not direct use adc_swtrigger_s32k146 example?
You can compare the different between these two project.

Best Regards,
