Did you do a pristine build (or just delete the build folder and build again)?

I added the following address and size to the pm_static.yml file, but the code still uses the partition information from the partitions.yml file. I’m not sure why the partition from the pm_static.yml file isn’t being used.

settings_storage:
address: 0xfe000
size: 0x1000

The latest part herr in your file sets the size and location of the settins partition:

settings_storage:
address: 0xfd000
size: 0x1000

You can change the address and size (this is just one page, you probaly want more). You also do not need to define everything in pm_static. It is OK to define what you want at specific locations, and then let the partition manager automatically place the rest (though en the end you probably want to fix it as you want static partitions when using DFU).

If you want to look at examples, you can look at some of the pm_static files in the SDK. One example is this one.

Hi,

I used below partition so how i can define the location of the partition in pm_static.yml?

I am new to the nRF SDK, so I would appreciate your help.

b0_container:

address: 0x0

orig_span: &id001

- b0

- provision

size: 0x9000

span: *id001

b0:

address: 0x0

size: 0x8000

provision:

address: 0x8000

size: 0x1000

s0:

address: 0x9000

orig_span: &id002

- app

size: 0x7a000

span: *id002

s0_image:

address: 0x9000

orig_span: &id003

- app

size: 0x7a000

span: *id003

app:

You define the location of the partition in pm_static.yml. Then, every time, the generated pm_config.h will reflect that.

Hi,

so how i can use pm_static.yml file partition in my firmware?

because i used storage_partition and this partition available in pm_config.h.if possible can you please provide me reference code.

#define TEST_PARTITION storage_partition

#define TEST_PARTITION_OFFSET FIXED_PARTITION_OFFSET(TEST_PARTITION)

#define TEST_PARTITION_DEVICE FIXED_PARTITION_DEVICE(TEST_PARTITION)

Hi,

No, the pm_config.h file should not be modified. This is automatically generated by the partition manager every time you build.

Hi,

I took the pm_static.yml file, added the address and size, and placed the file into the build directory.

Do I need to make any changes in the pm_config.h file? I'm not able to see the partition name in the pm_config.h file.

Often you will pick the auto generated pm_static.yml from the build folder and modify slightly if needed. you can also make a full or partial pm_static.yml that only change what you need. You can see many pm_static.yml fiels in the SDK that you can refer to. There is also description on how this works in the documetnation I linked to in my previous post.

Hi,

I am unable to see pm_static.yml file in my work space,i want to generate this file?if yes then can you please suggest me how i can i generate this file.

RE: flash address change when add CONFIG_BOOTLOADER_MCUBOOT=y

Einar Thorsrud — Tue, 15 Oct 2024 10:29:57 GMT

Note that this is a generated file so changes here will be lost if you make a new build. If you want to cange the partition layout you should do so in a pm_static.yml file (see Configuring static partitions).

Hi,

In the build/zephyr/include/generated/pm_config.h file, I made the following changes, and I was able to write data to address 0xfd000.

#define PM_SETTINGS_STORAGE_OFFSET 0xfd000 // 0xfc000

#define PM_SETTINGS_STORAGE_ADDRESS 0xfd000 //0xfc000

#define PM_SETTINGS_STORAGE_SIZE 0x1000 //0x2000

Hi,

There will be a partition for persistent storage in flash as well (such as settings which you can use for other things, and which is also used by the BT stack for bondign information). You can go to the build directory and type "ninja partition_manager_report" to see a representation of the parition layout tenerated by the partition manager (it is also possible in the nRF Connec for VS Code GUI if you select the build folder under application sand us eMemory report, but it does not currently show the partitions with SDK 2.7.0). See the Parition manager documentation for more details.

Hi,

Thanks for the support,

For BLE FOTA, we need to enable CONFIG_BOOTLOADER_MCUBOOT=y. If we want to write data to flash, how do we select the address for writing the data? Is it possible to see auto enable partition manager?

if possible can you give reference code for this.

When CONFIG_BOOTLOADER_MCUBOOT is selected, it will auto enable partition manager - and ignore DTS partitions altogether.
