rp2040: Use nvs fail. the prompt is written successfully, but cannot be read

[zhang-wenchao]

Describe the bug

Use nvs demo, the prompt is written successfully, but cannot be read

Add overlay

samples/nvs/boards add pico overlay

rpi_pico.overlay

&flash0 {
	partitions {
		compatible = "fixed-partitions";
		#address-cells = <1>;
		#size-cells = <1>;

		code_partition: partition@100 {
			label = "code";
			reg = <0x100 (DT_SIZE_M(1) - 0x100)>;
			read-only;
		};

		storage_partition: partition@100000 {
			label = "storage";
			reg = <0x100000  DT_SIZE_M(1)>;
		};
	};
};

Erase flash

 /usr/local/bin/openocd -f interface/cmsis-dap.cfg -f target/rp2040.cfg -c "init; reset init; flash erase_sector 0 0 last; reset; exit"

Build and flash

west build -b rpi_pico samples/subsys/nvs -- -DRPI_PICO_DEBUG_ADAPTER=cmsis-dap -DOPENOCD=/usr/local/bin/openocd -DOPENOCD_DEFAULT_PATH=/usr/local/share/openocd/scripts && west flash

@soburi You should be an expert on pico. Do you have time to look into this? I'm sorry to bother you, thank you very much for your time.

@soburi You should be an expert on pico. Do you have time to look into this? I'm sorry to bother you, thank you very much for your time.

While I am certainly a maintainer, I am not a full-time Zephyr developer, so this is a volunteer effort, and I cannot guarantee that I will be able to resolve the issue in a sufficiently short timeframe.

@zhang-wenchao, it seems that nothing is written to flash at all. Please enable flash debugging and rerun the test (the output can be limited to only one reboot).

How enable flash debugging，add CONFIG_FLASH_LOG_LEVEL_DBG=y in vain.

I am seeing a similar problem. My application uses NVS. It previously worked, but now it can only read NVS items that have already been written (it cannot erase them or overwrite new values to them). I've determined that changeset "6e3a1fda493a63806a315f56b57959ba57a2c9ba : manifest: hal_rpi_pico: Pull partial flash write changes from hal_rpi_pico" us the one where things broke on the Pico W (I haven't tried Pico 2 W yet). 6e3a1fd

[zhang-wenchao]

My hardware is broken, and I don't have a test environment right now. I'm waiting to buy a new one.

Is this an issue with the Zephyr NVS subsystem or the HAL architecture?
