Hi Paul,

No fix yet, but this workaround here might work: RE: Mass Example with External Flash not working with CONFIG_BOOTLOADER_MCUBOOT=y

Hi Yang,

If you are still struggling with this, take a look at this devzone thread right at the end:

https://devzone.nordicsemi.com/f/nordic-q-a/98797/mass-example-with-external-flash-not-working-with-config_bootloader_mcuboot-y

I had the same issue but on NOR flash in my case. Hope this helps.

Kind Regards

Julian

Hi, Amanda Hsieh

Can you identify the problem and the corresponding solution?

Hi, Amanda Hsieh

About 'FATFS chose the wrong device while using Partition Manager', i think it is a multiple file system compatibility probleam.

As i said, this PR only add that using Partition Manager which is LittleFS, NVS and Setting.

Therefore, FATFS is ignored.

Where should it get area_id from Partition Manager instead of DTS.

There are two steps to solving this problem:

1. Adding pm.yml file to generate FATFS partitions.

2. Change the interface it used to get flash_disks.area_id.

Hu Yang

Hi,

I removed that configs, and added `CONFIG_PM_OVERRIDE_EXTERNAL_DRIVER_CHECK=y` in prj.conf

But i still have this problem.

`disk_access_write()` gets soc flash not spi ext flash.

Hi,

[quote user="hu-yang"]I was added `CONFIG_PM_PARTITION_REGION_NVS_STORAGE_EXTERNAL=y` to my prj.conf, also `CONFIG_NVS=y` and `CONFIG_NVS_LOOKUP_CACHE=y` has benn select.[/quote]

Remove those configs.

I correct my answer:

You need to set the CONFIG_PM_OVERRIDE_EXTERNAL_DRIVER_CHECK=y in your project config file. Check out External flash memory partitions

If the external flash device is not using the QSPI NOR driver, you must enable CONFIG_PM_OVERRIDE_EXTERNAL_DRIVER_CHECK to override the Partition Manager’s external flash driver check, and the required driver must also be enabled for all applications that need it.

Hi, Amanda H

I was added `CONFIG_PM_PARTITION_REGION_NVS_STORAGE_EXTERNAL=y` to my prj.conf, also `CONFIG_NVS=y` and `CONFIG_NVS_LOOKUP_CACHE=y` has benn select.

But it also select the wrong device, see debug details as follow:

I want to add FATFS to my project,

are you sure i should add `CONFIG_PM_PARTITION_REGION_NVS_STORAGE_EXTERNAL=y` to my prj.conf?

In define device step, i thing it get a wrong device, see here:

There are pm_config file:

Hi,

You could enable CONFIG_PM_OVERRIDE_EXTERNAL_DRIVER_CHECK in the prj.conf. Check out External flash memory partitions.

By the way, in this PR partition_manager: add option to place partition in ext flash ,it adds the way to which partition region should be located in external flash memory but FATFS.
