Change SD during DFU gets error "SD Version failure"

The CPU is halted after programming and the chip needs to be reset for program execution to start, but I don't see any reset in your script.

Does it advertise if you run this command:

$ nrfjprog --program hex/bl_sd_app_s113.hex --chiperase --verify -r

? If not, please run "nrfjprog --readregs" and post the result here.

I have tried your files, flashing is OK but it is not advertising, i'm not sure what to check (I have an external crystal as well)

$ mergehex -m hex/tmp.hex hex/secure_bootloader_ble_s113_pca10100.hex  -o hex/bl_sd_app_s113.hex

It's usually quite straightforward to run an SDK example on a custom board. In most cases, it's enough to make minor configuration adjustments, such as changing the clock source as previously mentioned. The purpose of testing the hex files I've verified was to help isolate the issue.

Is the device advertising before the 2-minute timeout? You can return to the "scan" view in the app using the same phone or another one to confirm this.

I theoretically could, but it would require a lot of work, and I guess it will work but won't help understanding the error with the "real" project (it's a big project, diffing with examples is not easy)

RE: Change SD during DFU gets error "SD Version failure"

Would it be possible to run an SDK example on your board with minimal changes? For instance, by changing the 32KHz source to the internal RC oscillator if your board does not have the crystal mounted.

I don't have a nRF52833 DK, I have a custom board

RE: Change SD during DFU gets error "SD Version failure"

Vidar Berg — Fri, 20 Oct 2023 09:28:11 GMT

I see. Is there are reason you can't try with the hex files I uploaded?

[quote user="QuentinFarizon"]And I have tried doing the second step (BL incremented+SD+app)[/quote]

Is the device advertising after the BL+SD has been uploaded?

RE: Change SD during DFU gets error "SD Version failure"

QuentinFarizon — Thu, 19 Oct 2023 15:15:20 GMT

I have flashed my board with a Bootloader allowing new SD versions (forced softdevice_info_ok to always return true)
And I have tried doing the second step (BL incremented+SD+app)

I have set FDS_VIRTUAL_PAGES to 5

I still get GATT ERROR, at the end of the upload : drive.google.com/.../view

Thanks for confirming. I've tried to reproduce this error here with nRF5 SDK 17.1.0 and the nRF52833 DK but it worked for me here.

The only code change I made was this line in the bootloader code:

nrfutil command to generate the DFU package for the modified bootloader

# Generate DFU package for patched bootloader
nrfutil nrf5sdk-tools pkg generate --hw-version 52 \
 --bootloader secure_bootloader_ble_s113_pca10100_patch.hex \
 --bootloader-version 2 \
 --sd-req 0x0125 \
 --key-file keys/private.pem \
  /dfu_packages/patched_s113_bl.zip

And the nrfutil for the final update with the s140 Softdevice, bootloader, and application

nrfutil nrf5sdk-tools pkg generate --hw-version 52 \
 --bootloader secure_bootloader_ble_s140_pca10100.hex \
 --bootloader-version 3 \
 --application ble_app_buttonless_dfu_pca10100_s140.hex \
 --application-version 2 \
 --softdevice s140_sd.hex \
 --sd-req 0x0125 \
 --sd-id 0x0123 \
 --key-file keys/private.pem \
  dfu_packages/complete_s140.zip

Attached are the files I used for test. Can you try these and see if it works for you as well?

RE: Change SD during DFU gets error "SD Version failure"

QuentinFarizon — Tue, 03 Oct 2023 15:07:03 GMT

Vidar Berg Yes, as written : bootloader, with bumped version, allowing change of SD

I have even forced softdevice_info_ok to always return true, for now

RE: Change SD during DFU gets error "SD Version failure"

Vidar Berg — Mon, 02 Oct 2023 15:02:59 GMT

Have you patched the bootloader to allow updates from the s113 Softdevice variant to the s140 variant?

RE: Change SD during DFU gets error "SD Version failure"

QuentinFarizon — Mon, 02 Oct 2023 14:12:56 GMT

I have tried :
- DFU only the bootloader (bump version to 3), allowing change of SD => OK
- DFU BL (version 4) + SD + app => GATT ERROR when re-connecting to the bootlodare

RE: Change SD during DFU gets error "SD Version failure"

QuentinFarizon — Mon, 02 Oct 2023 14:09:29 GMT

I'm still trying to make it work, I have tried to do the above :
- DFU only the bootloader, with bumped version, allowing change of SD => OK
- DFU SD + app => SD version failure

RE: Change SD during DFU gets error "SD Version failure"

Vidar Berg — Mon, 12 Jun 2023 13:26:12 GMT

Yes.

RE: Change SD during DFU gets error "SD Version failure"

QuentinFarizon — Mon, 12 Jun 2023 13:01:37 GMT

Can I do the following ? :
- DFU only the bootloader, with bumped version, allowing change of SD
- DFU SD + app

RE: Change SD during DFU gets error "SD Version failure"

Vidar Berg — Fri, 06 Jan 2023 10:51:54 GMT

Correct.

RE: Change SD during DFU gets error "SD Version failure"

QuentinFarizon — Fri, 06 Jan 2023 10:51:34 GMT

For both updates then ?

RE: Change SD during DFU gets error "SD Version failure"

Vidar Berg — Fri, 06 Jan 2023 10:50:34 GMT

No problem. Yes, I forgot to add that you must bump the BL version number for each update.

RE: Change SD during DFU gets error "SD Version failure"

QuentinFarizon — Fri, 06 Jan 2023 10:48:54 GMT

Thanks !

For the first update, I must increase the Bootloader version, right ?

RE: Change SD during DFU gets error "SD Version failure"

Vidar Berg — Fri, 06 Jan 2023 10:37:57 GMT

You must include a new bootloader in the update when you are doing a major version update of the SD. This is a requirement set by the bootloader to ensure its Softdevice APIs always remain compatible with the Softdevice version currently present on the device. In other words, a major SD+app update will end up being rejected by the bootloader.

What you can do to work around this and allow update to a different Softdevice variant is to first update the modified bootloader (must be compatible with the old softdevice), then perform the BL+SD+app update.

[quote user="QuentinFarizon"]Do only one DFU of BL+SD+App with the modified bootloader and new SD[/quote]

The old bootloader will reject this update due to the ID check discussed earlier.

So, basically you have to perform the update in two stages:

- First, update to an intermediate bootloader without the ID check. This bootloader must be compatible with the s113 bootloader

- Update to the new s140 Softdevice , bootloader, and application

Thank Vidar Berg
I've read Replacing s140 with s340 softdevice but I'm unsure on the best strategy.

Which one is supposed to be working ?

Strategy 1 :
Do a first DFU of BL+SD+App with the modified bootloader, removing check on SD ID
Do a second DFU of SD+App, with new SD

Strategy 2 :
Do only one DFU of BL+SD+App with the modified bootloader and new SD

In that case, it is probably failing the check inside softdevice_info_ok() shown. You will need to modify the bootloader if you want to allow SD upgrades from one family to another (i.e s113 -> s140).

I think after the SD has been transfered
