MCUBoot not a compatible amount of sectors NRF54L15

[Fernando Fontes]

Hi guys,

I'm trying to do FOTA updates on my board and I was able so far to download the image but not able to apply it.

I've followed the academy FOTA over WiFi example but during bootup I see the following warning message:

[0:0:0.8,150] <wrn> mcuboot: Cannot upgrade: not a compatible amount of sectors

[0:0:0.8,156] <dbg> mcuboot: slot0 sectors: 180, slot1 sectors: 163, usable slot0 sectors: 179

What could be the issue here? On the partition manager I see both mcu_primary and mcu_secondary with the same size.

Please check my pm_static.yml:

EMPTY_0:
  address: 0xd800
  end_address: 0xe000
  placement:
    after:
    - mcuboot
  region: flash_primary

EMPTY_1:

    - app
    align:
      start: 0x1000
    before:
    - end
  region: flash_primary
  size: 0x6000

Also my sysbuild.conf:

SB_CONFIG_BOOTLOADER_MCUBOOT=y
SB_CONFIG_PARTITION_MANAGER=y

Any ideias? I'm trying to have a stable version with FOTA so that I can move to the production pilot.

Best regards,

Hi,

 

This exercise is mainly for the nRF7002-DK, which has a nRF5340+nRF7002 device.

To setup a DFU wise project for the nRF54L-series device(s), please see here:

https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-9-bootloaders-and-dfu-fota/topic/exercise-5-fota-over-bluetooth-low-energy/

 

I understand that you want to do DFU over Wi-Fi, but the setup-wise process around sysbuild/devicetree/mcuboot etc, is similar here.

 

Kind regards,

Håkon

Hi, 

Thank you for the reply.

Ok, but where can I see the pm_static.yml for the FOTA over bluetooth example? 

Best regards,

The generated partition layout will be found in build/partitions.yml file.

If you want to statically store this, copy it to application_folder/pm_static.yml

 

Kind regards,

Ok,

But flashing the application on l9/l9_e5 gives me exactly the same output:

*** Booting MCUboot v2.1.0-dev-9b4ae4cbc9e2 ***
*** Using nRF Connect SDK v3.1.1-e2a97fe2578a ***
*** Using Zephyr OS v4.1.99-ff8f0c579eeb ***

[0:0:0.1,414] <wrn> mcuboot: slot0 sectors: 182, slot1 sectors: 161, usable slot0 sectors: 181

Maybe it's my custom dts files the issue?

These are the partitions on the zephyr.dts generated file:

				partitions {
					compatible = "fixed-partitions"; /* in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:9 */
					#address-cells = < 0x1 >;        /* in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:10 */
					#size-cells = < 0x1 >;           /* in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:11 */

					/* node '/soc/rram-controller@5004b000/rram@0/partitions/partition@0' defined in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:13 */
					boot_partition: partition@0 {
						label = "mcuboot";     /* in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:14 */
						reg = < 0x0 0x10000 >; /* in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:15 */
					};

					/* node '/soc/rram-controller@5004b000/rram@0/partitions/partition@10000' defined in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:18 */
					slot0_partition: partition@10000 {
						label = "image-0";         /* in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:19 */
						reg = < 0x10000 0xa6000 >; /* in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:20 */
					};

					/* node '/soc/rram-controller@5004b000/rram@0/partitions/partition@b6000' defined in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:23 */
					slot1_partition: partition@b6000 {
						label = "image-1";         /* in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:24 */
						reg = < 0xb6000 0xa6000 >; /* in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:25 */
					};

					/* node '/soc/rram-controller@5004b000/rram@0/partitions/partition@15c000' defined in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:28 */
					storage_partition: partition@15c000 {
						label = "storage";         /* in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:29 */
						reg = < 0x15c000 0x9000 >; /* in zephyr/dts/vendor/nordic/nrf54l15_partition.dtsi:30 */
					};
				};

Please be aware that I don't have an external flash as the DK has.

These are the partitions on the zephyr.dts generated file:

It is highly likely related to your mcuboot configuration.

Can you try to only have this line set?

https://github.com/NordicDeveloperAcademy/ncs-inter/blob/main/l9/l9_e3_sol/spi/sysbuild.conf#L2

 

And remove/rename the sysbuild folder?
