Yes, no worries. When you are back and have the time, just submit information to this ticket.

Thank you! There were some issues with v14.0, but this is none of your concern.

I will actually be out of the country for work until 7/9, is it ok if I get back to you then with the memory dump?

Have a look at this thread as well.

Hello,

Can you provide a memory dump of your device? One after each try, one with iOS and one with Android. Can you run the following command?

nrfjprog --memrd 0x73000 --n 0xd000 > dump.txt

Are you updating from SDK 14.0 or 14.2?

Is this with iOS or Android?

Thanks!

So I changed two things that got me further along (at least with nRF Connect 4.22.3 on Android):

1) Removed the `--sd-boot-validation` as you said.
2) Changed

--sd-req 0x98,0x99,0x9E,0x9D,0xB7

--sd-req 0x9D

Without #2 the "SD req not met" pre-validate was failing. For some reason it was only seeing the last SD ID in the list, so removing all but the one matching the current firmware fixed it.

I'm still getting the same original error using the iOS DFU library, but not Android, so that's likely a separate issue I need to open with them.

Now I'm stuck here:

RE: Is it possible to update firmware via BLE DFU from v14 to v15 of the nRF5 SDK?

Øyvind — Fri, 14 Jun 2019 13:25:19 GMT

Hello again,

I've managed to reproduce the issue, and the issue seems to be

--sd-boot-validation VALIDATE_ECDSA_P256_SHA256

which was not supported in SDK14.2, but is new in SDK15.3.

The following call worked for me:

nrfutil pkg generate --application ble_app_hrs_pca10040_s132.hex --application-version 1 --softdevice s132_nrf52_6.1.1_softdevice.hex --bootloader secure_bootloader_ble_s132_pca10040.hex --bootloader-version 3  --hw-version 52 --sd-req 0x98,0x99,0x9E,0x9D,0xB7 --sd-id 0xB7 --app-boot-validation VALIDATE_ECDSA_P256_SHA256 --sd-boot-validation VALIDATE_ECDSA_P256_SHA256  --key-file private.pem hrs_dfu.zip

This updated the bootloader and softdevice to newest and installed the correct app.

Please try to remove sd-boot-validation and let me know how that works for you.

Kind regards,
Øyvind

Hi Josh,

I have not been able to reproduce your issue yet but it is work in progress. Discussing the issue with my team as well and we think there might be an issue with the:

--sd-boot-validation VALIDATE_ECDSA_P256_SHA256
--app-boot-validation VALIDATE_ECDSA_P256_SHA256

But will verify. In the mean time, please have look at the DFU tutorial (if you have not looked at this) it mentions: "For bootloader and softdevice update, please see the Appendix."

Kind regards,
Øyvind

RE: Is it possible to update firmware via BLE DFU from v14 to v15 of the nRF5 SDK?

I've been trying to update using the iOS DFU library (4.4.2) which is when I get the error mentioned above.

When I try to update using the Android nRF Connect app I get a totally different error ('dfq_req_handling: Prevalidate failed!'), but it makes it a farther along in the process.

I'll have to keep looking into this, but I think since the two DFU libraries act differently, it might be something wrong with the firmware or one of the libraries, and probably not something wrong with the DFU ZIP I'm generating.

Thanks,
Josh

Here is what we are using:

nrfutil settings generate 
    --family NRF52 
    --application $APP_HEX_FILE 
    --application-version $APP_FW_VERSION 
    --bootloader-version 3 
    --bl-settings-version 2
    $BOOT_SETTINGS_HEX_FILE

nrfutil pkg generate 
    --hw-version 52 
    --sd-req 0x98,0x99,0x9E,0x9D,0xB7 
    --sd-id 0xB7 
    --application $APP_HEX_FILE 
    --application-version $APP_FW_VERSION 
    --bootloader $BOOT_HEX_FILE
    --bootloader-version 3 
    --softdevice nrf5sdk/components/softdevice/s132/hex/s132_nrf52_6.1.1_softdevice.hex 
    --sd-boot-validation VALIDATE_ECDSA_P256_SHA256 
    --app-boot-validation VALIDATE_ECDSA_P256_SHA256 
    --key-file $PRIVATE_KEY_FILE
    $PKG_OUTPUT_FILE

I noticed that we never merge the $BOOT_SETTINGS_HEX_FILE and the $BOOT_HEX_FILE, and I'm thinking that this merged file is what actually should be passed to the "nrfutil settings generate --bootloader" option? Otherwise the default settings are used and the DFU firmware doesn't know it needs to upgrade the settings page.

I'll try this while waiting for an answer.

Thank You,
Josh

Hi Josh,

[quote user=""]I'm wondering if this is supposed to be possible, or if v15.3 is not backwards compatible (I didn't see anything in the documentation saying it's not compatible).[/quote]

Yes, you should be able to update from v14 to v15.3 using DFU.

[quote user=""]I am getting the error "Init command larger than expected.[/quote]

What command are you using when generating the DFU package?

Kind regards,
Øyvind
