Hello.
I try to connect SPI memory W25Q80 to nRF52840DK (in the future it will be my own board) but I have problem with device tree. I modified original files (nRF52840dk_nRF52840) but still I can't build project.
dts file:
aliases {
led0 = &led0;
led1 = &led1;
led2 = &led2;
led3 = &led3;
pwm-led0 = &pwm_led0;
in0 = &input0;
in1 = &input1;
in2 = &input2;
in3 = &input3;
bootloader-led0 = &led0;
mcuboot-button0 = &input0;
mcuboot-led0 = &led0;
watchdog0 = &wdt0;
//spi-flash0 = &mx25r64;
spi-flash0 = &w25q80;
};
&qspi {
status = "disabled";
pinctrl-0 = <&qspi_default>;
pinctrl-1 = <&qspi_sleep>;
pinctrl-names = "default", "sleep";
// mx25r64: mx25r6435f@0 {
// compatible = "nordic,qspi-nor";
// reg = <0>;
// /* MX25R64 supports only pp and pp4io */
// writeoc = "pp4io";
// /* MX25R64 supports all readoc options */
// readoc = "read4io";
// sck-frequency = <8000000>;
// 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 = <67108864>;
// has-dpd;
// t-enter-dpd = <10000>;
// t-exit-dpd = <35000>;
// };
};
&spi3 {
compatible = "nordic,nrf-spim";
status = "okay";
cs-gpios = <&gpio1 14 GPIO_ACTIVE_LOW>;
pinctrl-0 = <&spi3_default>;
pinctrl-1 = <&spi3_sleep>;
pinctrl-names = "default", "sleep";
w25q80: w25q80@0 {
compatible = "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <8000000>;
jedec-id = [EF 40 14];
size = <1048576>;
};
};
Implementation in my W25Q80.c file:
const struct device *ex_flash_device = DEVICE_DT_GET(DT_ALIAS(spi-flash0));
I wanted to use "zephyr/samples/drivers/spi_flash" example from Zephyr repo, is it good choice for this type of memory?
Best regards
PW
