Hello，
I am using ncs1.7.1, qspi + mx25r64 external flash ota it works well, but I don't know how to change qspi to spi.
I need your help thanks
I change the parament .overlay file
/ {
chosen {
nordic,pm-ext-flash = &FM25Q08B;
};
};
&spi0 {
compatible = "nordic,nrf-spim";
status = "okay";
sck-pin = <28>;
mosi-pin = <26>;
miso-pin = <24>;
cs-gpios = <&gpio0 30 GPIO_ACTIVE_LOW>;
FM25Q08B:FM25Q08B@0 {
compatible = "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <0x400000>;
label = "FM25Q08B";
jedec-id = [ C2 20 18 ];
size = < 0x8000000 >;
};
};

I find the code at ncs\bootloader\mcuboot\boot\zephyr\main.c I need binding the flash but I don't know how to do it. Can you help me solve this problem. Thank you.
Personally I think JEDEC_SPI_NOR_0_LABEL and CONFIG_XTENSA is important.
