core voltage not adjusted

muaxi8 — Tue, 10 Aug 2021 10:02:36 GMT

LX2080a custom board.

The Uboot print has one line output: core voltage not adjusted。

Is this a voltage adjustment for the CPU core ?

Is there any problem with this adjustment failure? My board is now unable to Bringing up secondary CPUs. Is it related to this ?

Yes.

During the system initialization VID is read from the processor to adjust VDD accordingly.

When VDD is not adjusted then power consumption could be non-optimal (higher), but there could not be functional issues.

Not related.
