Issue with flash definitions on nCS v2.9.0

Hello,

I have dts files defined with flash partitions which build & work fine on nCS v2.6.0

But the moment i add same definitions to dts of nCS v2.9.0 it gives me redefinition error:

-- Found BOARD.dts: /opt/nordic/ncs/v2.9.0/zephyr/boards/nordic/nrf52840dk/nrf52840dk_nrf52840.dts
devicetree error: Label 'boot_partition' appears on /soc/flash-controller@4001e000/flash@0/partitions/partition@0 and on /soc/flash-controller@4001e000/flash@0/partitions/partition@f8000
CMake Error at /opt/nordic/ncs/v2.9.0/zephyr/cmake/modules/dts.cmake:295 (execute_process):
  execute_process failed command indexes:

If i try to define flash partitions in dts it says:

You are using Partition Manager to define the partitions. Devicetree definitions are ignored for this build.

If i define in pm_static file as :

nvs_storage:
  address: 0xD7000
  end_address: 0xf7000
  placement:
    align:
      start: 0x1000
    before:
    - device_info
  region: flash_primary
  size: 0x20000

& try to fetch it anyways in code as:

// #define NVS_PARTITION_OFFSET      PM_NVS_STORAGE_ADDRESS
// #define NVS_PARTITION_SIZE        PM_NVS_STORAGE_SIZE
// #define NVS_PARTITION_DEVICE      DEVICE_DT_GET(PM_NVS_STORAGE_DEV)

// #define NVS_PARTITION_OFFSET_TEMP PM_DEVICE_INFO_ADDRESS
// #define NVS_PARTITION_SIZE_TEMP   PM_DEVICE_INFO_SIZE
// #define NVS_PARTITION_DEVICE_TEMP DEVICE_DT_GET(PM_DEVICE_INFO_DEV)

#define NVS_PARTITION_OFFSET PM_NVS_STORAGE_ADDRESS
#define NVS_PARTITION_SIZE   PM_NVS_STORAGE_SIZE
#define NVS_PARTITION_DEVICE DEVICE_DT_GET(DT_NODELABEL(flash0))

#define NVS_PARTITION_OFFSET_TEMP PM_DEVICE_INFO_ADDRESS
#define NVS_PARTITION_SIZE_TEMP   PM_DEVICE_INFO_SIZE
#define NVS_PARTITION_DEVICE_TEMP DEVICE_DT_GET(DT_NODELABEL(flash0))

	fs_temp.flash_device = NVS_PARTITION_DEVICE_TEMP;
	if (!device_is_ready(fs_temp.flash_device)) {
		printk("Flash device %s is not ready\n", fs.flash_device->name);
		return;
	}
	fs_temp.offset = NVS_PARTITION_OFFSET_TEMP;

I get errors as :

error: 'PM_NVS_STORAGE_ADDRESS' undeclared (first use in this function); did you mean 'PM_SETTINGS_STORAGE_ADDRESS'?
   28 | #define NVS_PARTITION_OFFSET PM_NVS_STORAGE_ADDRESS

Hi,

Did you use partition manager in NCS v2.6.0 in combination with dts partitioning? If so, you still need to use both in v2.9.0 as well.

There might also be some migrating that needs to be done w.r.t configs and naming, but you should be able to see this here https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity.html

Are the node-properties you're trying to set up present in the dts? Could you share the dts and/or overlay where you set up the NVS device and/or other flash devices?

Kind regards,
Andreas

Hello AHaug ,

Yes i did.

AHaug said:

No, because if i enable partitioning in both dts & pm_static, it throws redundant declarations error during compilation as below:

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_guide_2.9.html , This shows nothing as Required Change, and i see no impact of required changes for flash partition definition v2.6.0 onwards:

I couldn't find any samples in nCS v2.9.0 demonstrating a partition creation in pm_static.yml and usage of that partition in code.
I tried to create one, even that fails to build as attached.

Hello,

So far was able to work around most issues, now just stuck with the final one which is getting flash0 label:
main.c:22: undefined reference to `__device_dts_ord_126'

Have attached the sample project as in below, kindly help me resolve the same:

AHaug ,

I observed. that nCS v2.9.0 has no flash0 bindings in any of its dts definitions.
Hence cannot access flash device as

DEVICE_DT_GET(DT_NODELABEL(flash0))

Now i need to understand how to define & access it from pm_static.yml
My sample pm_static.yml looks like:

app:
  address: 0x0
  size: 0xD7000
  region: flash_primary

nvs_storage:
  address: 0xD7000
  size: 0x20000
  region: flash_primary

dummy_partition:
  address: 0xF7000
  size: 0x7000
  region: flash_primary

settings_storage:
  address: 0xFE000
  size: 0x2000
  region: flash_primary

Now if i get to access any dummy partition say:

#define PARTITION_DEVICE_DUMMY DEVICE_DT_GET(DT_CHOSEN(zephyr_flash_controller))
// OR
#define PARTITION_DEVICE_DUMMY DEVICE_DT_GET(DT_NODELABEL(flash0))

const struct device *dev = PARTITION_DEVICE_DUMMY;

printk("Dummy Partition Device: %s\n", dev->name);

I get the same error as :
undefined reference to `__device_dts_ord_125'

How to access a partition & flash0 from pm_static.yml into code.?
