Partition Manager for External Memory doesn't create correctly the partitions.

[FlavioPiracicaba]

Hello,

   I created the regions.yml and pm_static.yml. If I enable this flag the compiler works well

but doesn't create the correct partitions I wrote on pm_static.

##CONFIG_PM_PARTITION_REGION_SETTINGS_STORAGE_EXTERNAL=y

  If I uncomment, these errors appears:

-- Found partition manager static configuration: C:/Nordic/peripheral_uart/pm_static.yml
Dropping partition 'nonsecure_storage' since it is empty.

CMake Error at C:/ncs/v2.3.0-rc1/nrf/cmake/partition_manager.cmake:304 (message):

   Could you help me?

Thanks,

Hi Dejan,

For the case can be compilated it's possible to generate logs. First of all, I think if you could see the full project instead parts of it in github will be easier.

It's all here: https://github.com/flavioafferreira/peripheral_uart_new

I am using a PCA10095 nRF5340-DK

Basicaly I created some Threads.  When I press button 1, send some informations through bluetooth, Button 2 try to save on external memory, The AD device is reading 4 ports.

Thanks,

Flavio.

Hi,

Could you please specify where you want to place your partitions? What is your intention when using pm-static.yml and regions.yml? What would be your desired partition layout?

Best regards,
Dejan

Hello Dejan,

   I want to create partitions on external memory mx25r64.

   Each partition will store some variables structures as a circular buffer.

This is the layout I want:

  Could you help me?

Thanks,

Flavio.

Hi,

From your project link I see that you use pm-static.yml, but you should be using pm_static.yml instead. You could have a look at how to configure static partitions in the documentation.

Best regards,
Dejan

Hey Flavio,

I was just about to open a ticket with the same issue that you reported.

In my opinion, there is an issue with the way the pm.yml.settings file is written. If CONFIG_PM_PARTITION_REGION_SETTINGS_STORAGE_EXTERNAL is enabled, the partition ends up incompletely defined and is fed to the partition-manager script to be resolved (that's why you're getting the KeyError: 'size' error).

To solve this, you need to patch the pm.yml.settings file so that instead of :

#include <autoconf.h>

settings_storage:
  placement:
    before: [tfm_storage, end]
#ifdef CONFIG_PM_PARTITION_REGION_SETTINGS_STORAGE_EXTERNAL
  region: external_flash
#else
    align: {start: CONFIG_PM_PARTITION_ALIGN_SETTINGS_STORAGE}
#endif
  inside: [nonsecure_storage]
  size: CONFIG_PM_PARTITION_SIZE_SETTINGS_STORAGE

you'll have:

#include <autoconf.h>

settings_storage:
#ifdef CONFIG_PM_PARTITION_REGION_SETTINGS_STORAGE_EXTERNAL
  region: external_flash
#endif
  placement:
    before: [tfm_storage, end]
    align: {start: CONFIG_PM_PARTITION_ALIGN_SETTINGS_STORAGE}
  inside: [nonsecure_storage]
  size: CONFIG_PM_PARTITION_SIZE_SETTINGS_STORAGE

Please notice the macro definition scope, now, when CONFIG_PM_PARTITION_REGION_SETTINGS_STORAGE_EXTERNAL is enabled, the resulting partition definition ends up being correctly defined: has the 'size' prop (among other things).

Hope this helps,

Best wishes,

V
