MPC5775E EQADC Sampling Problem

Dear NXP Community,

I'm having a problem with my new EQADC configuration. I would like to describe my configuration below.

For A phase current by adjusting the EQADC_A ADC0 internal ADC - AN24,

For B phase current by adjusting the EQADC_A ADC1 internal ADC - AN25,

For C phase current by adjusting the EQADC_B ADC0 internal ADC - AN26,

For DC Bus voltage by adjusting the EQADC_B ADC1 internal ADC - ANB1 and I observe that EQADC is sampling successfully.

I want to sample by adjusting the EQADCB ANB21 and ANB23 channels to measure temperature, but when I make the necessary settings for these channels, I cannot sample.

My settings on the configurator are as follows.

Since the configurations of phases A, B, C and DC Bus Voltage are similar, I did not include them all. I set the RotorTemp and StatorTemp channels and groups for ANB21 and ANB23. They are as follows.

When I check the EQADC's RFIFO2 and RFIFO3, I don't see any sampling. Why can I only convert for one ADC channel under each ADC Hardware Unit? How can I reproduce this?

Could you help me?

Best regards.
