Please be verbose in sharing logs, so that I can understand what is occurring on your end.

What is the error that you are seeing?

Instead of sharing one-and-one file, please share a .zip.

Objective is to run Simultaneous updates for both cores of the nRF5340 for SPI with board nrf7002dk/nrf5340/cpuapp/ns

Can you verify it works?

Thank you.

RE: mcuboot + spi ext flash + overwrite + tfm fails to jump to application

Håkon Alseth — Fri, 30 Jan 2026 12:32:38 GMT

Sorry, you are right. Look at this one, and check the SPI related configurations, ie. sysbuild.conf and sysbuild/ folder here:

[quote userid="2115" url="~/f/nordic-q-a/126603/mcuboot-spi-ext-flash-overwrite-tfm-fails-to-jump-to-application/559183"]L9_e3_sol (https://github.com/NordicDeveloperAcademy/ncs-inter/tree/main/l9/l9_e3_sol/spi) [/quote]

And combine this into your current project.

Kind regards,

Håkon

Hi Håkon,

I have a nrf7002dk and i just tested Simultaneous updates for both cores of the nRF5340 for SPI with board nrf7002dk/nrf5340/cpuapp/ns

I modified

mcuboot.conf

# Step 6.2 - MCUboot should use external flash
CONFIG_NORDIC_QSPI_NOR=n
CONFIG_BOOT_MAX_IMG_SECTORS=256

# Step 1.2 - Enable SPI driver for MCUboot

CONFIG_SPI=y
CONFIG_SPI_NOR=y
CONFIG_SPI_NOR_SFDP_DEVICETREE=y
CONFIG_SPI_NOR_FLASH_LAYOUT_PAGE_SIZE=4096
# QSPI drivers are enabled by defualt for some chips.
# Disable it explicitly to be sure QSPI is disabled.
CONFIG_NORDIC_QSPI_NOR=n 

# required by SPI driver
CONFIG_MULTITHREADING=y

and

sysbuild.conf

SB_CONFIG_BOOTLOADER_MCUBOOT=y
SB_CONFIG_MCUBOOT_USE_ALL_AVAILABLE_RAM=y

# Step 6.3 - Configure project to use external flash for DFU
SB_CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY=y
# Step 3.1 - For SPI, we need to set  this
SB_CONFIG_PM_OVERRIDE_EXTERNAL_DRIVER_CHECK=y

# Step 7.2 - Add b0n image
SB_CONFIG_SECURE_BOOT_NETCORE=y

# Step 7.3 - Set up multiple partitions
SB_CONFIG_MCUBOOT_UPDATEABLE_IMAGES=2

# Step 7.4 - Add support to netcore for DFU
SB_CONFIG_NETCORE_APP_UPDATE=y

# Step 7.5 - Add support to mcuboot for updating
# two cores simultaneously
SB_CONFIG_MCUBOOT_NRF53_MULTI_IMAGE_UPDATE=y

# Step 7.6 - Simultaneous FOTA does not support rollback
SB_CONFIG_MCUBOOT_MODE_OVERWRITE_ONLY=y

rest are exact same as in the example.

I am getting the same error. Cannot jump to the first image slot.

Thank you.

Hi,

Glad other samples work on your board.

Yes, nonsecure is supported:

https://github.com/NordicDeveloperAcademy/ncs-inter/blob/main/l9/l9_e5_nrf5340_both_sol/sample.yaml#L13

The exercises are aimed for a DK, so it is important that you test these on your custom board.

Kind regards,

Håkon

RE: mcuboot + spi ext flash + overwrite + tfm fails to jump to application

Hej Håkon,

The pointer *esf in this case will hold details of the CPU registers at the time of fault occurring. You can then use lesson2, exercise 2 (https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-2-debugging/topic/exercise-2-11/) to backtrace to where in the code this occurred, using addr2line.

I got ??.. as an answer.

I tried Exercise 3 – DFU with external flash and it works on my board, at least it jumps to main and runs blinky (haven't tested update).

Can you verify that Simultaneous updates for both cores of the nRF5340 for SPI with board nrf7002dk/nrf5340/cpuapp/ns works?

Thank you.

Hi,

In order to get a bit of a better overview, its important to debug this step-by-step, as it seems that mcuboot is failing to find your application image at this point.

Did you try to run L9 E3 first with board nrf7002dk/nrf5340/cpuapp/ns, to see if this works with the board?

RE: mcuboot + spi ext flash + overwrite + tfm fails to jump to application

Hi,

Have you entered a debug session to see if the main application boots at all?

Given the log, it seems to try to boot your application via TF-M.

When using L9_e3_sol (https://github.com/NordicDeveloperAcademy/ncs-inter/tree/main/l9/l9_e3_sol/spi) for board nrf7002dk/nrf5340/cpuapp/ns, I see this debug output once is CONFIG_MCUBOOT_LOG_LEVEL_DBG=y enabled:

And the main application just runs blinky.

These debug messages ("D:") are because I effectively have unknown content in the external flash.

Try entering debug mode, and see where your firmware is stuck.

If you see it is stuck in TF-M, try to disable logging with these config's:
