how to layout net-core flash

[leisir]

i changed the net-core flash partition and saved it to pm_static.yml.
everything is ok while i build multi-image(mcuboot, cpuapp, b0n, cpunet) until my partner wants to build single net-core image.
it always prompts "Partition manager failed: Incorrect amount of gaps found in static configuration.".
is here anyone who can help me to solve this problem?

complier prompt this:

Partition 'nvs_storage' is not included in the dynamic resolving since it is statically defined.
Partition manager failed: Incorrect amount of gaps found in static configuration. There must be exactly one gap in the static configuration to support placing the dynamic partitions (such as 'app'). Gaps found (0): The most common solution to this problem is to fill the smallest of these gaps with statically defined partition(s) until there is only one gap left. Alternatively re-order the already defined static partitions so that only one gap remains.

IC: nrf5340

single image command (NG):
west build -d build_nrf5340dk_nrf5340_cpunet -b nrf5340dk_nrf5340_cpunet -p

multi image command (OK):
 west build -d build_allinone -b nrf5340dk_nrf5340_cpuapp . -DCONF_FILE=prj_multiple_image.conf

Hi,

What sample are you trying to build? The hci_rpmsg sample ?

What version of nRF Connect SDK (NCS) are you using? v1.6.0 ?

[leisir]

I'm sorry for the incomplete information.

the SDK version is 1.6.1, and borad is nrf5340dk.

here is the prj_multiple_image.conf file:

###multiple_image

We enabled CONFIG_BOOTLOADER_MCUBOOT and CONFIG_BLE_NETWORK_CORE to build 4 images: mcuboot, b0n, net-core-image, app-core-image.

We plan to reserve a small amount of storage for the net-core for future use.

[Sigurd]

multi-image(mcuboot, cpuapp, b0n, cpunet) until my partner wants to build single net-core image.

A solution might be to don't apply the pm_static.yaml on the single net-core image build, or have a separate pm_static.yaml for that build.

[leisir]

we give up the 4-in-1(mcuboot, cpuapp, b0n, cpunet) compile method now. but we cannot fixed the cpunet compile error.  would you give me some help?

compile command:

west build -d build -b nrf5340dk_nrf5340_cpunet

compile error:
