Place mcuboot_secondary in winbond W25Q64JV extenal flash memory for FOTA using NCS 1.9.1, nrf9160dk

[Praveen Deshmane]

Hi Nordic Team,

I would like to place mcuboot_secondary in winbond W25Q64JV extenal flash memory for FOTA. I would like perform HTTP application and full modem fota.
As my app_update.bin size is very huge and internal flash memory is alomost 90% full, I could not able to do fota update.

Envrionment Details 

SDK : NCS 1.9.1 
Device :  nrf9160dk - customized one
External flash memory - winbond W25Q64JV 8MB

I have followed many devzone tickets, I could not able to place mcuboot_secondary in winbond W25Q64JV extenal flash memory.

I am getting this build error.



Please tell me why I am getting this error. My configurations are correct? How to do it in a proper way?
Its been two weeks I have gone through all the related tickets in devzone, about placing mcuboot_secondary in external flash memory for fota unfortunately none of them worked for me.

Here is my test code.

 im830.rar

Please help me to resolve this issue. Your help will be greately appreciated.

NOTE:

I request to you please dont give any solutions that are done with MX25R64 external flash memory and SDK version more than 1.9.1. I want it in NCS 1.9.1 SDK.

Best Regards

Hi, have you tried setting CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY=y in your prj.conf?

[Praveen Deshmane]

Hello BenKrug,

Thank you for your reply.

if I add CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY=y, It will look like this




I will get a build time error.

 - Praveen

[BenKrug]

can you take a print of your build error?

[Praveen Deshmane]

Hi BenKrug,

I delete my build folder first and rebuild it by adding CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY=y. 

During build i can see this warning message

warning: PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY (defined at
C:/Users/ift_praveen/ncs/v1.9.1/nrf\subsys\partition_manager/Kconfig:109) was assigned the value 'y'
but got the value 'n'. Check these unsatisfied dependencies: (n || MCUBOOT) (=n). See http://docs.ze
phyrproject.org/latest/reference/kconfig/CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY.html and/or look
up PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY in the menuconfig/guiconfig interface. The Application
Development Primer, Setting Configuration Values, and Kconfig - Tips and Best Practices sections of
the manual might be helpful too.

and build fails after some time like this.

Oh, the issue is you don't have CONFIG_BOOTLOADER_MCUBOOT or CONFIG_MCUBOOT, try setting one of them and see what happens. That's exactly what the build error is saying with the missing dependency.

EDIT: I saw now that you have CONFIG_BOOTLOADER_MCUBOOT set in the prj.conf file

[Praveen Deshmane]

Hello BenKrug,

CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY='y' is by default enabled if we set CONFIG_BOOTLOADER_MCUBOOT=y I think.

- Praveen

[BenKrug]

I don't think so, cause my code had the CONFIG_BOOTLOADER_MCUBOOT=y but when I added the CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY it said that in the build it was set to 'n'

[Praveen Deshmane]

Even though if I set both CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY=y and CONFIG_BOOTLOADER_MCUBOOT=y the issue still persists. any Idea?

- Praveen

[BenKrug]

try CONFIG_MCUBOOT, could be something that NCS v1.9.1 needs, its the missing dependency according to the build error
