External flash reading jesd216, "SFDP magic 000000 invalid"

[DoubleAmaing]

Hi，

I make a customer board and used GD25Q80C as the external Flash IC (not MX25);

Read the sfdp bfp of Flash by jesd216 sample (zephyr \ samples \ drivers \ jesd216),But it failed and prompted "SFDP magic 000000 invalid";

However, when I replaced GD25Q80C with MX25R64, it was successful;

My configuration is as follows:

I basically haven't changed the configuration of samples, only the IO port has been modified;

Can you see what the problem is?

The specifications for this IC are as follows

&spi2 {
	compatible = "nordic,nrf-spi";
	status = "okay";
	cs-gpios = <&gpio0 15 GPIO_ACTIVE_LOW>;
	pinctrl-0 = <&spi2_default>;
	pinctrl-1 = <&spi2_sleep>;
	pinctrl-names = "default", "sleep";
	mx25r64: mx25r6435f@0  {
		compatible = "jedec,spi-nor";
		reg = <0>;
		spi-max-frequency = <8000000>;
		jedec-id = [c8 40 14];
		size = <8388608>;//67108864
		wp-gpios = <&gpio0 22 GPIO_ACTIVE_LOW>;
		hold-gpios = <&gpio0 24 GPIO_ACTIVE_LOW>;
	};
};

	spi2_default: spi2_default {
		group1 {
			psels = <NRF_PSEL(SPIM_SCK, 0, 17)>,//19
				<NRF_PSEL(SPIM_MOSI, 0, 20)>,//20
				<NRF_PSEL(SPIM_MISO, 0, 13)>;//21
		};
	};

	spi2_sleep: spi2_sleep {
		group1 {
			psels = <NRF_PSEL(SPIM_SCK, 0, 17)>,//19
				<NRF_PSEL(SPIM_MOSI, 0, 20)>,//20
				<NRF_PSEL(SPIM_MISO, 0, 13)>;//21
			low-power-enable;
		};
	};

Hi

Changing what bit is the QE one was addressed in this Zephyr pull request: https://github.com/zephyrproject-rtos/zephyr/pull/42334 

I also see that you're using the MX25 " mx25r64: mx25r6435f@0" in your project, so if there are more differences between the GD25 and the MX25 you haven't taken into consideration you should make a GD25 overlay setting up the flash correctly, (on what write/read OCs you want to use, what frequency to use and the JEDEC ID (and potentially the sfdp-bfp).

Best regards,

Simon
