ncs external flash ota change qspi to spi

[Август]

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.

I also test the flash, after ota there are no data in the flash.

Could you try with the sample uploaded by Håkon here: https://devzone.nordicsemi.com/f/nordic-q-a/82686/fota-smp-very-slow/343080#343080 

I was able to perform BLE DFU with qspi external flash. I first built and flashed the sample:

• west build -b nrf52840dk_nrf52840 -p && west flash

Then I set CONFIG_BT_DEVICE_NAME="HELLO" in /smp_svr/prj.conf and built it again:

• west build -b nrf52840dk_nrf52840 -p 

Then I uploaded the file smp_svr/zephyr/app_update.bin to the phone, and performed DFU using the nRF Connect Device Manager app:

As you can see in the end of the video, the device is advertising with "HELLO", which means the update was successful. 

By the way, this blog post may be useful: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/ncs-dfu 

Best regards,

Simon

Update:

For some reason it was not possible to play the video I uploaded, so I uploaded it again in zipped format:

Hi

Thank you for you response.qspi + mx25r64 external flash ota it works well,but I need spi + mx25r64.

I will continue to implement this method, once successful, I will share my method and joy with you. 

Thank you.

Ah, sorry. I totally forgot that you used SPI (even though that was the main topic of this issue).

Sounds good. Use DFU over Bluetooth and the sample uploaded in my last reply as guidance on how to implement BLE DFU. If you don't get it to work please tell me and I'll look into it.

Best regards,

Simon

hi

I have tried it but it can't work, personally I think we should change spm 

img_mgmt_impl_write_image_data and mcuboot.

Hope you can find another simple way.

Thank you.
