OTA Update Softdevice + Bootloader error

[dilbert168]

I try to update/replace the code in a nRF52 board from 3rd party (Fanstel).  They only able to provide the private key which I can create the zip file but not able to give info what version of Softdevice loaded.

I am using the nRF5_SDK_17.0.2_d674dde for 

- secure_bootloader_ble_s132_pca10040.hex

- s132_nrf52_7.2.0_softdevice.hex

Using a batch file to create the zip file

set BOOT=secure_bootloader_ble_s132_pca10040
set SOFT=s132_nrf52_7.2.0_softdevice
set KEY=private.pem
set ZIP=Secure_Bootloader

nrfutil pkg generate --hw-version 52 --sd-req 0x101 --sd-id 0x101 --key-file %KEY% --bootloader-version 1 --bootloader %BOOT%.hex --softdevice %SOFT%.hex %ZIP%.zip

when I use the nRF52-DK board to perform OTA

nrfutil dfu ble -ic NRF52 -pkg Secure_Bootloader.zip -p COM15 -n "DfuTarg" -f

I get the following error : 

pc_ble_driver_py.exceptions.NordicSemiException: Extended Error 0x07: The array of supported SoftDevices for the update does not contain the FWID of the current SoftDevice.

Hello,

So the issue is that in your DFU image, you say that the receiver needs to have a softdevice with an ID 0x0101, which it looks like the receiving nRF doesn't currently have programmed.

You can try to set the --sd-req 0x00, which doesn't require any specific softdevices to already be programmed (as your image includes a softdevice either way). Then the device should accept it.

Best regards,

Edvin

I gather more info for this board.  The bootloader & Softdevice (s132_nrf52_6.x.x) is few years ago version.

using the " --sd-req 0xA8,0xAF,0xB7", it show different error conditions

Do you think a old version Bootloader can be updated ??

1. when trying yo update just the BL or both BL+SD, it shows this error

File "c:\tools\python\python38\lib\site-packages\nordicsemi\dfu\dfu_transport_ble.py", line 684, in __get_response
raise NordicSemiException('Response Code {}'.format(get_dict_key(DfuTransport.RES_CODE, resp[2])))
pc_ble_driver_py.exceptions.NordicSemiException: Response Code InsufficientResources

2. when trying to update just the SofDevice, the DFU started but fails at 98% when the error

Board already flashed with connectivity firmware.

If you update the softdevice to a different version, you need to update the bootloader as well. The reason behind this behavior is that if you end up with a bootloader that doesn't use the correct softdevice version, then you have bricked the device (in case you don't have a debugger, which end products typically doesn't have). 

So you need to either do an app-only update, or you can do a SD+BL update, or a combination, APP-SD-BL.

If it is the standard bootloader from the SDK, then I think it should be fine. 

[dilbert168]

But as indicated in #1, if I try doing BL+SD, it returns "Response Code InsufficientResources"

Do you think any other setting I missed ?

[Edvin]

Did you program the bootloader yourself, or was it pre-programmed when you got it? And if it was pre-programmed, can you erase it and program your own bootloader, or is that not an option?
