NCS read flash GD25LQ32EEIGR

[yoyou]

Hi,

NCS1.9.1, VSCode, nRF52840

i want to read flash GD25LQ32EEIGR,using qspi_flash (that in  \v1.9.1\zephyr\tests\boards\altera_max10\qspi)

#define MAX_NUM_OF_SECTORS		1024
#define NUM_OF_SECTORS_TO_TEST		4
#define FLASH_SECTOR_SIZE		65536
#define TEST_DATA_LEN			4

void test_qspi_flash(void)
{
	const struct device *flash_dev;
	uint32_t i, offset, rd_val, wr_val;
	uint8_t wr_buf[4] = {0xAA, 0xBB, 0xCC, 0xDD};
	uint8_t rd_buf[2];

	#define CONFIG_SOC_FLASH_NIOS2_QSPI_DEV_NAME "QSPI"

	flash_dev = device_get_binding(CONFIG_SOC_FLASH_NIOS2_QSPI_DEV_NAME);
	zassert_equal(!flash_dev, TC_PASS, "Flash device not found!");

	for (i = 0U; i < NUM_OF_SECTORS_TO_TEST; i++) {
		TC_PRINT("\nTesting: Flash Sector-%d\n", i);
		offset = FLASH_SECTOR_SIZE * i;

		/* Flash Erase Test */
		TC_PRINT("	Flash Erase Test...");
		zassert_equal(flash_erase(flash_dev,
				offset, FLASH_SECTOR_SIZE),
				TC_PASS, "Flash erase call failed!");
		zassert_equal(flash_read(flash_dev, offset,
				&rd_val, TEST_DATA_LEN),
				TC_PASS, "Flash read call failed!");
		/* In case of erase all bits will be set to 1 */
		wr_val = 0xffffffff;
		zassert_equal(rd_val != wr_val,	TC_PASS,
					"Flash Erase Test failed!!");
		TC_PRINT("PASS\n");


		/* Flash Write & Read Test */
		TC_PRINT("	Flash Write & Read Test...");
		wr_val = 0xAABBCCDD;
		zassert_equal(flash_write(flash_dev, offset,
				&wr_val, TEST_DATA_LEN),
				TC_PASS, "Flash write call failed!");
		zassert_equal(flash_read(flash_dev, offset,
				&rd_val, TEST_DATA_LEN),
				TC_PASS, "Flash read call failed!");
		zassert_equal(rd_val != wr_val,	TC_PASS,
					"Flash Write & Read Test failed!!");
		TC_PRINT("PASS\n");


		/* Flash Unaligned Read Test */
		TC_PRINT("	Flash Unaligned Read Test...");
		zassert_equal(flash_write(flash_dev, offset + sizeof(wr_val),
				&wr_buf, sizeof(wr_buf)),
				TC_PASS, "Flash write call failed!");
		zassert_equal(flash_read(flash_dev, offset + sizeof(wr_val) + 1,
				&rd_buf, sizeof(rd_buf)),
				TC_PASS, "Flash read call failed!");
		zassert_equal(memcmp(wr_buf + 1, rd_buf, sizeof(rd_buf)),
				TC_PASS, "Flash Write & Read Test failed!!");
		TC_PRINT("PASS\n");
	}
}

log:flash devece not found!

&qspi {
        compatible = "nordic,nrf-qspi";
        #address-cells = < 0x1 >;
        #size-cells = < 0x0 >;
        status = "okay";
        label = "QSPI";
    	sck-pin = < 0x13 >;

        GD25LQ32E: GD25LQ32E_@0 {
                compatible = "nordic,qspi-nor";
                reg = < 0x0 >;
                writeoc = "pp4io";
                readoc = "read4io";

                label = "GD25LQ32EEIGR";
                jedec-id = [ C2 28 17 ];
                sfdp-bfp = [ E5 20 F1 FF FF FF FF 03 44 EB 08 6B 08 3B 04 BB EE FF FF FF FF FF 00 FF FF FF 00 FF 0C 20 0F 52 10 D8 00 FF 23 72 F5 00 82 ED 04 CC 44 83 68 44 30 B0 30 B0 F7 C4 D5 5C 00 BE 29 FF F0 D0 FF FF ];

                t-exit-dpd = < 0x88b8 >;
        };
};

i don't know how to write overlay file,

                writeoc = "pp4io";

                readoc = "read4io";

                sck-frequency = < 0x7a1200 >;

                label = "GD25LQ32EEIGR";

                jedec-id = [ C2 28 17 ];

                sfdp-bfp = [ E5 20 F1 FF FF FF FF 03 44 EB 08 6B 08 3B 04 BB EE FF FF FF FF FF 00 FF FF FF 00 FF 0C 20 0F 52 10 D8 00 FF 23 72 F5 00 82 ED 04 CC 44 83 68 44 30 B0 30 B0 F7 C4 D5 5C 00 BE 29 FF F0 D0 FF FF ];

                size = < 0x4000000 >;

                has-dpd;

                t-enter-dpd = < 0x2710 >;

                t-exit-dpd

I don't know the meaning of the blue words,

Can you take a look at this this case, which I think is somewhat similiar but with another qpsi flash device:
https://devzone.nordicsemi.com/f/nordic-q-a/85983/qspi-flash-sample-project-error/

The data in blue as specific for the flash device, so just keep them as-is.

Hi,

thanks for reply, wo read your link.

i can runing with mx25r64 flash on DK,it's work well.

but change to GD25LQ32EEIGR,log:flash devece not found!

&qspi {
	compatible = "nordic,nrf-qspi";
	#address-cells = < 0x1 >;
	#size-cells = < 0x0 >;
	reg = < 0x40029000 0x1000 >, < 0x12000000 0x8000000 >;
	reg-names = "qspi", "qspi_mm";
	interrupts = < 0x29 0x1 >;
	status = "okay";
	label = "QSPI";
	sck-pin = < 0x13 >;
	io-pins = < 0x14 >, < 0x15 >, < 0x16 >, < 0x17 >;// MISO=IO0  MOSI=IO1  IO2  IO3
	csn-pins = < 0x11 >;	// CS#

	mx25r64: mx25r6435f@0 {
		compatible = "nordic,qspi-nor";
		reg = < 0x0 >;
		writeoc = "pp4io";
		readoc = "read4io";
		sck-frequency = < 0x7a1200 >;
		label = "MA25R64"; //   GD25LQ32E
		jedec-id = [ C2 28 17 ];
		sfdp-bfp = [ E5 20 F1 FF FF FF FF 03 44 EB 08 6B 08 3B 04 BB EE FF FF FF FF FF 00 FF FF FF 00 FF 0C 20 0F 52 10 D8 00 FF 23 72 F5 00 82 ED 04 CC 44 83 68 44 30 B0 30 B0 F7 C4 D5 5C 00 BE 29 FF F0 D0 FF FF ];
		size = < 0x4000000 >;
		has-dpd;
		t-enter-dpd = < 0x2710 >;
		t-exit-dpd = < 0x88b8 >;
	};
};

Can you try this one? You likely need to change the overlay file to work with your board.

Hello,Kenneth,

thanks for your reply.

i' have change the pin in overlay file.

&uart0 {
	status = "okay";
	label = "UART_0";
	current-speed = < 0x1c200 >;
	tx-pin = < 0x08 >;
	rx-pin = < 0x28 >;
	rx-pull-up;
	rts-pin = < 0xFFFFFFFF >;
	cts-pin = < 0xFFFFFFFF >;
};
&uart1 {
	status = "disabled";
	label = "UART_1";
};
&spi2 {
	status = "disabled";
	label = "UART_1";
};
&egu2 {
	status = "disabled";
};
&egu3 {
	status = "disabled";
};
&egu4 {
	status = "disabled";
};


&qspi {
	status = "okay";
	sck-pin = < 0x13 >;
	io-pins = < 0x15 >, < 0x14 >, < 0x18 >, < 0x17 >;// MISO=IO0  MOSI=IO1  IO2  IO3
	csn-pins = < 0x16 >;

	GD25LQ32E: GD25LQ32E_@0 {
		compatible = "nordic,qspi-nor";
		reg = < 0x0 >;
		writeoc = "pp4io";
		readoc = "read4io";
		sck-frequency = < 0x7a1200 >;
		label = "GD25LQ32EEIGR";
		jedec-id = [ C2 28 17 ];
		sfdp-bfp = [ E5 20 F1 FF FF FF FF 03 44 EB 08 6B 08 3B 04 BB EE FF FF FF FF FF 00 FF FF FF 00 FF 0C 20 0F 52 10 D8 00 FF 23 72 F5 00 82 ED 04 CC 44 83 68 44 30 B0 30 B0 F7 C4 D5 5C 00 BE 29 FF F0 D0 FF FF ];
		size = < 0x4000000 >;
		has-dpd;
		t-enter-dpd = < 0x2710 >;
		t-exit-dpd = < 0x88b8 >;
	};
};

the pin PWR_1V8  voltage is 1.8V.(Measure with a multimeter)

The code I supplied should run as-is on the nRF52840-DK with no changes, does it work then?

Are you trying to interface your flash device from the nRF52840-DK in this case? I can see the supply voltage is different, so I don't know how this would work.
