Hello,
We have the custom board with nRF54H20. The VDD_EXT pin is used to power some GPIO ports of nRF54H20 (P1/P2/P7).
The voltage we see on VDD_EXT is about 1.3V instead of 1.8V as we expected.
1) Could you please clarify how we can manage the output of VDD_EXT properly?
2) Is there a setting we could use with our firmware to get correct voltage on VDD_EXT?
3) The datasheet on nRF54H20 says that there is a switch for VDD_EXT pin. How can we use it?
Thanks.
