FS26 TRK2 UV fault

[hbsantos]

I'm using FS26 with s32k344 and the FS_OVUV_REG_STATUS register shows undervoltage on TRK2 through SPI. But I don't have any load on TRK2, just two capacitors: 2.2uF/50V and 100nF/100V. I measured the TRK2 voltage with a multimeter and oscilloscope and it's equal to 5V, that is, it's correct. Could someone help me to solve this?

Hi hbsantos

Can you show me your schematic?

I want to see those capacitors, your problem sounds like you're affected by a voltage divider so I want take a look your connection

If you have any problems sharing your scheme through the community, I recommend opening a ticket on our support page so we can talk more confidently.

I will be waiting for your response

Have a great day and best of luck.
