Bad cell count for /ahb/spi@1f000000/flash@0/partitions

Installing and Using OpenWrt

Hi,
during startup of my Archer C7 V2 i see these message:

kern.err kernel: [ 0.370040] OF: Bad cell count for /ahb/spi@1f000000/flash@0/partitions

What does it mean ?
Should I be worried ?

regards Klaus

It means your flash is fucked (ish).

Carry on. You should have enough free cells for a while yet. Get a new device when your Archer no longer boots.

No. This message is harmless, and doesn't indicate any physical issue. It came up here before, see for example this recent topic.

Ah, good to know. The symptoms match (those described through the links) for C7v2, whose parent DTS qca9558_tplink_archer-c.dtsi has:

&spi {
	status = "okay";

	flash@0 {
		compatible = "jedec,spi-nor";
		reg = <0>; // <-- here
		spi-max-frequency = <25000000>;

		mtdparts: partitions {
			compatible = "fixed-partitions";
			#address-cells = <1>;
			#size-cells = <1>;
		};
	};
};
