Hi,

Sorry for the late reply. Please enable the following configs:

CONFIG_PM_PARTITION_REGION_LITTLEFS_EXTERNAL=y
CONFIG_PM_OVERRIDE_EXTERNAL_DRIVER_CHECK=y

Hi, ok. I asked just because we're on a tight schedule. Thank you for the quick response.

Hi,

Thanks for the files. I could not find the clues on my side, so I ask the team to look into them. Please kindly give us time to investigate the issue.

Thanks.

Hi, have you got any progress on what the problem could be? Are there any files missing?

RE: MCUBoot without Partition Manager

BenKrug — Fri, 10 Mar 2023 11:11:29 GMT

The overlay file I've sent is already updated, but okay. So I'm sending the custom board files, .overlay, pm.yml and prj.conf files, with this you should have everything you need.
devzone.nordicsemi.com/.../updated-files.zip

RE: MCUBoot without Partition Manager

Amanda Hsieh — Thu, 09 Mar 2023 20:43:25 GMT

Please upload the latest overlay file. Thanks.

it happens only when CONFIG_PM_PARTITION_SIZE_LITTLEFS is 0xf000 or more

RE: MCUBoot without Partition Manager

Amanda Hsieh — Thu, 09 Mar 2023 19:34:45 GMT

Does the issue only happen when the CONFIG_PM_PARTITION_SIZE_LITTLEFS is 0x6000? If not, is it possible to provide the log and the updated overly?

Hi, I don't have it in the QSPI bus, as I'm using a nrf52832 it does not even include a QSPI bus, I have the flash SPI definitions on the dts file for the custom board:

 &spi1 {
	 compatible = "nordic,nrf-spi";
	 status = "okay";
	 pinctrl-0 = <&spi1_default>;
	 pinctrl-1 = <&spi1_sleep>;
	 pinctrl-names = "default", "sleep";
	 clock-frequency = <20000000>;
	 mx25r16: mx25r1635f@0 {
		compatible = "jedec,spi-nor";
		reg = <0>;
		spi-max-frequency = <33000000>;
		jedec-id = [c2 28 15];
		size = <DT_SIZE_M(16)>;
	};
 };

I forgot to add this piece of code before, sorry.

Hi,

Not sure what causes the issue, but the overlay seems you are using qpsi for mx25r16. If you disable qpsi as following

&qspi {
	status = "disabled";
};

L114 &mx25r16 will not work because the parent's node &qspi is disabled. To use SPI_NOR driver with your external mx25r16, it should have the thing like this example . Here is my overlay for your reference:

RE: MCUBoot without Partition Manager

Hi,

Could you provide the memory layout for the partition, partitions.yml under build folder, overlay, and config files? If you are using pm_static.yml, please also share it.

-Amanda H.

RE: MCUBoot without Partition Manager

BenKrug — Wed, 08 Mar 2023 13:48:39 GMT

even when the value is 0x7000, it still gives this error:

RE: MCUBoot without Partition Manager

BenKrug — Wed, 08 Mar 2023 13:05:58 GMT

I'm getting this error now when I set CONFIG_PM_PARTITION_SIZE_LITTLEFS to any value bigger than 0xf000:

do you know what could it be?

RE: MCUBoot without Partition Manager

Amanda Hsieh — Tue, 07 Mar 2023 20:43:25 GMT

Check the CONFIG_PM_PARTITION_SIZE_LITTLEFS value.

-Amanda H.

RE: MCUBoot without Partition Manager

BenKrug — Tue, 07 Mar 2023 19:53:25 GMT

Now I'm having one more problem, the partition for littleFS is getting set as 0x6000, even though on the pm.yml file it's set as 0x7000, I tried to change the value but nothing changed that final result, always get 0x6000.

It finally compiled!! Now I'm going to test if the basic functions are still working with the partition manager instead of the devicetree. Thank you.

RE: MCUBoot without Partition Manager

Amanda Hsieh — Tue, 07 Mar 2023 15:10:25 GMT

Hi,

Could you provide the overlay and config files?

The 'PM_MCUBOOT_SECONDARY_ID' undeclared issue is usually caused by the setting inside the overlay. Make sure the overlay has the following section

/ {
	chosen {
		nordic,pm-ext-flash = &mx25r64;
	};
};

[quote user="BenKrug"]I'm finding weird is that the flash size is going down to 232kB even though the flash has 512kB, that is making my code overflow the flash in 47kB[/quote]

Is it possible to provide the log for the overflow?

-Amanda H.

RE: MCUBoot without Partition Manager

BenKrug — Tue, 07 Mar 2023 13:05:00 GMT

Another thing I'm finding weird is that the flash size is going down to 232kB even though the flash has 512kB, that is making my code overflow the flash in 47kB, but I can't reduce the code any more than I've already done. Is this a bug or is there a configuration I can change to fix that?

RE: MCUBoot without Partition Manager

I made the changes you showed, but now I'm getting this error:

RE: MCUBoot without Partition Manager

Hi,

Are you trying to allocate a separate partition for littleFS? If so, you can take a look at this post.

The pm_static.yml example is for nRF5340 which has two cores and that might mislead you, so I have updated it for nRF52. I also update my example in the previous reply with the pm_static.yml as

mcuboot_primary:
    orig_span: &id001
        - mcuboot_pad
        - app
    span: *id001
    address: 0xc000
    size: 0xf2000
    region: flash_primary
mcuboot_primary_app:
    orig_span: &id002
        - app
    span: *id002
    address: 0xc200
    size: 0xf1e00

settings_storage:
    address: 0xfe000
    size: 0x2000
    region: flash_primary

mcuboot_secondary:
    address: 0x0
    size: 0xf2000
    device: MX25R64
    region: external_flash
    

littlefs_storage:
    address: 0xf2000
    size: 0x7000
    device: MX25R64
    region: external_flash
 
external_flash:
   address: 0xf9000
   size: 0x707000
   device: MX25R64
   region: external_flash

It would look like this

RE: MCUBoot without Partition Manager

Unfortunately, the Partition Manager cannot be disabled, but you can use static partitions to modify the memory layout as you desire. See Configuring static partitions and this example.

Hi, I tried to compile the code following this process, however it uses the Partition Manager(in the build folder you can see there is a pm.config) and I don't want to use it, that was my original question, is there a way to use the DFU Update without using the partition manager?
