Hi Dejan,

thank you very much for your help adding the chosen option and the three kconfig parameters solved my problem, I really appreciate you effort to help me solve my problem.

Kind regards,

Hi Paul,

You would need to have "chosen" added in an overlay file for both the application and bootloader as it is shown in external flash memory partitions. Since SPI NOR driver requires multithreading support and is required to be enabled in bootloader configuration, you could try to add the following configuration options to your bootloader configuration in <your_project_folder>\child_image\mcuboot.conf

CONFIG_SPI_NOR=y
CONFIG_PM_OVERRIDE_EXTERNAL_DRIVER_CHECK=y
CONFIG_MULTITHREADING=y

Best regards,
Dejan

Hi Dejan,

I started my project based on different samples such as the peripheral sample, but it grew bigger and bigger. It is basically a BLE project, and the last issue is to add DFU. If I don't use the SPI Flash the application works fine. But if I want to use the Flash and have DFU function, I get the described compile error.

What other information do you need?

Kind Regards

Paul

Hi Paul,

Is your project based on any of the NCS samples?

Hi Dejan,

I don't have an overlay file. I made a custom dts file

Kind regards

Hi Paul,

Do you have any overlay file?

Unfortunately I cannot share my whole dts file

Hi Paul,

Could you share your dts and overlay files?

Best regards,

Hi Dejan,

I am not sure what line you mean but here is the section of ordinal 90:

/* Node's dependency ordinal: */
#define DT_N_S_soc_S_spi_40004000_ORD 90
#define DT_N_S_soc_S_spi_40004000_ORD_STR_SORTABLE 00090

/* Ordinals for what this node depends on directly: */
#define DT_N_S_soc_S_spi_40004000_REQUIRES_ORDS \
	4, /* /soc */ \
	5, /* /soc/interrupt-controller@e000e100 */ \
	9, /* /soc/gpio@50000000 */ \
	28, /* /pin-controller/spi1_default */ \
	30, /* /pin-controller/spi1_sleep */

Is this the write code line?

Kind Regards Paul

Hi Paul,

Could you show the line with ordinal 90 from your devicetree_generated.h?

Best regards,
Dejan

I added CONFIG_BOOTLOADER_MCUBOOT=y in my prf.conf.

I use ncs v2.5.0

Kind Regards

Paul

Hi Paul,

It seems that your flash settings are enabled.

Where did you try to add CONFIG_BOOTLOADER_MCUBOOT=y?

Which nRF Connect SDK version do you use?

Best regards,
Dejan

Paul123 — Thu, 11 Jan 2024 08:49:35 GMT

Hi Dejan,

thank you for your response. How do I enable the flash support in my project?

my prf.conf looks like this:

CONFIG_SPI=y
CONFIG_FLASH=y
CONFIG_FLASH_PAGE_LAYOUT=y
CONFIG_FLASH_MAP=y
CONFIG_NVS=y
CONFIG_SPI_NOR=y
CONFIG_STDOUT_CONSOLE=y
CONFIG_FLASH_JESD216_API=y

My project woks with this setup as long as I don't set

CONFIG_BOOTLOADER_MCUBOOT=y

Do I need to add some defines to mcuboot.conf?

I tried adding these defines to mcuboot.conf but I still get the compiling error.

The only thing that works is, if I remove the Flash from my devicetree.dts.

But then I can't use the flash at all so this is not an option for me.

Kind Regards

Paul

Hi,

[quote user=""]What does this error mean? Especially what means the error undefined reference to `__device_dts_ord_90'? [/quote]

This is coming from devicetree_generated.h located in build/zephyr/include/generated. It might mean that you have not specifically enabled flash support in your project configuration.

Best regards,
Dejan
