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.
