ADC triggering on the wrong pin

Hello,

I ran into an issue on the s32k311 with the RTD 5.0.0. I am using Tresos 29.0.0.

So, I want to use Adc0_s14 on the pin Ptc16 but it is triggering on the pin Ptb0. The channel is always reading close to max count because ptb0 is my Spi chip select. The channel is supposed to read close to 1.0V. To confirm, I changed Ptb0 to a Gpio and I triggered the Adc while toggling the pin. I was now reading values alternating between 0 and max count.

I feel like the issue is similar to this one: https://community.nxp.com/t5/S32K/S32K3-ADC-Channcal-configure-problem/td-p/1527680

Do we have a fix for the RTD 5.0.0 concerning this type of issue?

This issue is discussed here: S32K311_S32K310 ADC mux-mode channels was abnormal
