Found the problem!
The problem was the low level of the operating voltage.
Raising the level of the operating voltage to 3.3V solved the problem!

Now i have an issue with the MAC address, but i'll create a new ticket for that.

Hi,

It can be due to initialization of the external flash, which seems to fail:

[00:00:00.349,487] <err> spi_nor: Device id 00 00 00 does not match config c2 28 17

Could you try to remove/disable the external flash?

&spi4 {
    status = "disabled";
};

Kind regards,

Håkon
