Flash overflow?

[BenA]

Hello,

I'm trying to merge together a couple of sample projects to make a prototype (in particular, the LTE-BLE gateway, and AWS-IoT samples) - to run on the nRF 9160DK

When I try and compile, I get the following errors:

/opt/nordic/ncs/toolchains/20d68df7e5/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd: zephyr/zephyr_pre0.elf section `text' will not fit in region `FLASH'

/opt/nordic/ncs/toolchains/20d68df7e5/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd: region `FLASH' overflowed by 119504 bytes

How can I resolve this please? Or is it just too big to try and fit onto the Dev Kit?

Regards,

Ben

Hi Ben,

The error does mean that your compiled application is too big to fit on the memory. May I ask how you arrive at this application?

It might be helpful if you can share your compiled Devicetree and Kconfig. They are in the files named zephyr.dts and .config, under <build directory>/zephyr.

Regards,

Hieu

Hi - I'm trying to add BLE scanning into the AWS_IoT sample (the BLE was copied from the BLE_LTE sample)

0207.zephyr.dts5078.config.txt

Hi Ben,

I just tried to merge the configuration of the LTE BLE Gateway sample into the AWS IoT sample, and did not run into your issue. There is plenty of space left in the application and MCUboot. Only TF-M is close to limit, but I believe that is intentional.

I am a little curious why there are a number of LVGL configurations set in your compiled Kconfig. CONFIG_LVGL itself is not set though, so I think it shouldn't impact the size, but I cannot be sure.

Could you please elaborate your steps in more details? Are you certain that you haven't added anything besides what is already in the two samples?

Could you please also check your build log to see at which image you encounter the problem? If you are not sure, please give me the full build log.

Also, what version of NCS are you using?

Please be informed that our team is currently having reduced availability due to the Easter holiday. There will be some delays in our response during this time, but we will respond to you at the earliest opportunity. Our apologies for the inconvenience.

[BenA]

That's odd! Would it be possible for you to share your project so I can check that I can build it successfully?

I'm using nRF Connect SDK v2.5.2

Hi Ben,

Sorry for the long wait. We have had the Easter holiday.

From your build log, the failure happened during the application compilation, but I can't see any further what the problem could be.

Here is my project. I used nRF Connect SDK v2.6.0, but there shouldn't be much difference. Please let me know if you need v2.5.2 specifically.

Thanks Hieu,

I can successfully build the project you shared. I tried adding simple BLE scanning, but I'm getting the following error:

ASSERTION FAIL [err == 0] @ WEST_TOPDIR/zephyr/subsys/bluetooth/host/hci_core.c:331

 I guess this is another configuration I need to set somewhere?

On another note - I don't quite understand how you've added the BLE to the config - as kconfig parameters such as CONFIG_BT=y are in a separate .conf file.

I added them to the main prj.conf for the purposes of this build - but am I missing something? How to I tell it to also read lte_ble_gateway.conf?

Have you flashed the HCI application onto the nRF52840 device on the DK? If not, that would be the problem. The design is that the nRF9160 will run only the BLE Host application, and the nRF52840 will run the BLE Controller application.

Please refer to the documentation of the LTE BLE Gateway sample for more information.

You guessed right. The other .conf file can be included in the build.

If you are building from the command line with west, refer to this guide: Application Development — Zephyr Project documentation (nRF Connect SDK) (nordicsemi.com).

If you are building with the nRF Connect for VS Code Extension, you can specify additional .conf file to be included in a build configuration:

You might also want to know that the nRF Connect SDK also include a solution for different "build types" that makes use of different .conf files. However, that's not what I am using here.

Hi - yes, I've built and flashed the hci_lpuart sample to the nRF52 - but I'm still getting the same issue:
