Implement bootloader in NCS SDK

[QuentinD]

Hello,

Until now I was working on an application based on the nRF5 SDK: it is this application that is used by my customers.
Now I would like to use the NCS SDK to continue to have the latest features and bug fixes.

Here I almost finished redeveloping my new application (based on NCS SDK) to work like my old one (based on nRF5 SDK) but I have a problem with the bootloader...

My board (contains an nrf 52840) has no buttons and no external memory (so I will have to overwrite existing code when I do an update) but does have a UART.
I need to be able to update the application but also the bootloader.

Here are my questions:

• I think I have to go into recovery mode to be able to update in this situation? But how can I do it if I don't have a button?
• The update files will be sent by another microcontroller on the board via the uart: can you tell me more about what I need so that the other microcontroller can communicate with the nrf 52840 to send the files to the bootloader? (files ? protocol ?)
• Is it possible to update a device that would work with the nRF5 SDK (secure_bootloader_uart_mbr_pca10056) to keep the old bootloader but updating the softdevice+app with the new application (NCS SDK)?

THANKS

Hi,

I think I have to go into recovery mode to be able to update in this situation? But how can I do it if I don't have a button?

One option is to use "serial recovery with wait", 

A colleague of mine has written this repository with samples, where you the serial recovery samples containing samples for serial recovery using both the waiting and mcumgr method and regular UART serial recovery. I suggest you have a look at these samples to see if they fit your project or if you're able to tailor them to your project

The update files will be sent by another microcontroller on the board via the uart: can you tell me more about what I need so that the other microcontroller can communicate with the nrf 52840 to send the files to the bootloader? (files ? protocol ?)

I recommend you to have a look at devzone.nordicsemi.com/.../doing-an-fota-via-ble-using-a-nordic-development-kit

Is it possible to update a device that would work with the nRF5 SDK (secure_bootloader_uart_mbr_pca10056) to keep the old bootloader but updating the softdevice+app with the new application (NCS SDK)?

Yes, but there are things you will have to take in mind. I recommend you to have a look at  One bootloader to rule them all which refers to a sample created by a colleague of mine showing how to port a nRF5 app to become a NCS app  Hang with nRF5 SDK 17.1.0 Bootloader and nRF Connect SDK 2.1.0 application . This case, https://devzone.nordicsemi.com/f/nordic-q-a/100639/nrf5340-multi-image-dfu-update-over-ble-remote-error-in-value-3 does also to some extent explain some of the procedure

Let me know if this is enough to get you started! 

Kind regards,
Andreas

Hello,

Thank you very much for your answer.

I've been working on this for 2 weeks but unfortunately I still have problems...

Here at the moment, I'm trying to find a way to update the devices that are with my customers (with the nRF5 SDK) so that it's not too complicated for us and for them to manage the updates of old devices and new ones (with NCS SDK). I think the simplest solution would be to manage to only update the app of the devices that are with my customers (therefore keeping the old bootloader and the softdevice present in the devices).

To do this, I tried to do like Vidar Berg with his project 2273.peripheral_lbs.zip (devzone.nordicsemi.com/.../hang-with-nrf5-sdk-17- 1-0-bootloader-and-nrf-connect-sdk-2-1-0-application) but unfortunately there must be things I forgot because it doesn't work.

When I compile my project and flash it, it works on my device. On the other hand, if I send the update to a device working with the nRF5 SDK, it accepts the update but afterwards it is blocked.

Here are the problems I'm seeing that I don't know how to fix:

- In the prj.conf file of my project, I put "CONFIG_FLASH_LOAD_OFFSET=0x27000" but it is the value 0xC000 which is put (I have a warning for that in the logs).

- In my mcuboot.cong file in the child_image folder, I added "CONFIG_SINGLE_APPLICATION_SLOT=y". Despite this, I have to provide memory in my pm_static.yml file for mcuboot_secondary otherwise I get a compilation error: do you know why?

Here are my DFU logs:

Here I only put the MCUboot to simplify but then I would like to add the CONFIG_SECURE_BOOT.

Thanks for your help !

Hi,

I see you're using NCS v2.3.0 from your logs. This sample is only working with NCS v2.1.0 out of the box and it will not be updated as it is not an official sample. I recommend you to make it work with NCS v2.1.0 before attempting to port it to v2.3.0.

After you've made it work for v2.1.0 you can have a look at the changelogs in the SDK versions to see what changes has been made w.r.t DFU and the bootloaders. There are certain changes in Zephyr in between v2.1.0 and v2.2.0 that will have to be implemented.

Kind regards,
Andreas

Hello,

Here I can now update the application of my devices which worked with the nrf5 SDK by uploading an Application file made with the NCS SDK.

The memory of these devices now look like this:
MBR
softdevice
application (from NCS SDK)
bootloader (from nrf5 SDK)

In my application which came from the nrf5 SDK, I had to do this so that the bootloader remains in DFU mode after the reboot:

err_code = sd_power_gpregret_clr(0, 0xffffffff);
VERIFY_SUCCESS(error_code);

err_code = sd_power_gpregret_set(0, BOOTLOADER_DFU_START);
VERIFY_SUCCESS(error_code);

// Signals that DFU mode must be entered in the power management module
nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_GOTO_DFU);

Since in my case I have an application coming from the NCS SDK with a bootloader coming from the nrf5 SDK on the device, I also need to configure this register so that the bootloader remains in DFU mode. Could you tell me how I can do the same thing using the NCS SDK functions?

Thank you

Hi,

The following should work:

       nrf_power_gpregret_set(NRF_POWER, 0xB1);
       NVIC_SystemReset();

Kind regards,
Andreas

[QuentinD]

Thanks for your answer but how can I call this function in the NCS SDK?

[AHaug]

Hi,

The lines I gave you was how to use it in NCS.

To test it you can for instance add this code to a basic hello world and see that GPREGRET changes. When you want to use it in your project, change gpregret_set to use the magic 0xB1 instead of increment it.

Open a new hello_world in vs code and modify it to include the following lines and see that gpregret changes value.

#include <hal/nrf_power.h>

        uint8_t val = nrf_power_gpregret_get(NRF_POWER);

        printk("Old GPREGRET val: %u\n", val);

        nrf_power_gpregret_set(NRF_POWER, ++val);

        k_sleep(K_MSEC(1000));

        NVIC_SystemReset();

 

Kind regards,
Andreas

Thank you

Currently I only have the MCUboot + app but I would also like to add the NSIB in addition.

Here is the problem I have: if I load the .hex of the complete project, there is no problem (it boots into the application and it works). Now if I try to update the bootlaoder I notice that it writes the file instead of the application and not in s1... Do you have any idea why?

There is a small peculiarity to my project: I defined CONFIG_SINGLE_APPLICATION_SLOT=y so as not to have to double the memory of my application (works very well if I only have the MCUboot).

My chil_image/mcuboot.conf:

#-------------------------------------------- MCUBoot--------------------------------------------
# Bootloader version (To make s1_image bootable with nRF Secure Immutable Bootloader, the value of CONFIG_FW_INFO_FIRMWARE_VERSION for s1_image must be bigger than the one for original image):

Here it's what I did to update the bootloader:
1. Reboot device (button on the PCA10056)

2. Send the cmd: mcumgr -c my_config image upload Application\TA_Smart\zephyr\signed_by_mcuboot_and_b0_s1_image_update.bin
