west build failed with undefined node label 'qspi'

[snowuyl]

I found the following section in nrf52840.dtsi. But I can't find similar section in nrf52832.dtsi. Could I copy this section from nrf52840.dtsi to nrf52832.dtsi for solving west build error?

qspi: qspi@40029000 {
            compatible = "nordic,nrf-qspi";
            #address-cells = <1>;
            #size-cells = <0>;
            reg = <0x40029000 0x1000>, <0x12000000 0x8000000>;
            reg-names = "qspi", "qspi_mm";
            interrupts = <41 NRF_DEFAULT_IRQ_PRIORITY>;
            status = "disabled";
        };

Hello,

The nRF52832 does not include the QSPI peripheral, so you will need to select one of a SPI instance instead.

Best regards,

Thanks for your reply! I have replaced QSPI with SPI. But I encounter flash_erase() failed with error code  -19.

&spi1 {
status = "okay";

cs-gpios = <&gpio0 13 GPIO_ACTIVE_LOW>;
pinctrl-0 = <&spi1_default>;
pinctrl-1 = <&spi1_sleep>;
pinctrl-names = "default", "sleep";

w25q32: w25q32jv@0 {
compatible = "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <8000000>;
jedec-id = [ef 40 16];
size = <0x400000>;
has-dpd;
t-enter-dpd = <3500>;
t-exit-dpd = <3500>;
};

w25q256: w25q256jv@0 {
compatible = "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <8000000>;
jedec-id = [ef 40 19];
size = <0x2000000>;
has-dpd;
t-enter-dpd = <3500>;
t-exit-dpd = <3500>;
};
};

Source code to call flash_erase() is as follows.

int flashNorInit(void)
{
const struct device *flash_dev;
int rc;

flash_dev = DEVICE_DT_GET(DT_ALIAS(spi1flash0));

if (!device_is_ready(flash_dev)) {
printk("%s: device not ready.\n", flash_dev->name);
return -1;
}

printk("\n%s SPI flash testing\n", flash_dev->name);
printk("==========================\n");

/* Write protection needs to be disabled before each write or
* erase, since the flash component turns on write protection
* automatically after completion of write and erase
* operations.
*/
printk ("\nTest 1: Flash erase\n");

/* Full flash erase if SPI_FLASH_TEST_REGION_OFFSET = 0 and
* SPI_FLASH_SECTOR_SIZE = flash size
*/
rc = flash_erase(flash_dev, SPI_FLASH_TEST_REGION_OFFSET,
SPI_FLASH_SECTOR_SIZE);
if (rc != 0) {
printk("Flash erase failed! %d\n", rc);
} else {
printk("Flash erase succeeded!\n");
}

return 0;
}

Log messages are as follows.

I have added following configuration in prj.conf. Do I need to add other configuration?

# flash
CONFIG_FLASH=y
CONFIG_FLASH_JESD216_API=y
CONFIG_FLASH_PAGE_LAYOUT=y
CONFIG_MPU_ALLOW_FLASH_WRITE=y
CONFIG_SOC_FLASH_NRF=y
# SPI
CONFIG_SPI=y
CONFIG_SPI_NOR=y
