Problem using an external flash together with MCUBOOT

[Paul123]

I have I custom board based on a NRF52832. I also have an external SPI Nor flash I use to store data.

I want to add MCUBOOT and don't use the external flash to store the second image. In fact I use the serial recovery if the DFU fails.

If I compile my project with

CONFIG_BOOTLOADER_MCUBOOT=n

I get no compiler error.

If I set

CONFIG_BOOTLOADER_MCUBOOT=y

I get the following compiler error (I couldn't insert it as code):

What does this error mean? Especially what means the error undefined reference to `__device_dts_ord_90'?

Hi,

What does this error mean? Especially what means the error undefined reference to `__device_dts_ord_90'? 

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

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 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]

I added CONFIG_BOOTLOADER_MCUBOOT=y in my prf.conf.

I use ncs v2.5.0

Kind Regards

Paul

Hi Paul,

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

Best regards,
Dejan

[Paul123]

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 share your dts and overlay files?

Best regards,
