nRF Connect for Desktop to download hex file error

[xixili]

I use nRF Connect for Desktop to download hex file(nrf52810).

Use the following example：

nRF5_SDK_15.3.0_59ac345\examples\dfu\secure_bootloader\pca10040e_ble +
nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\ble_app_buttonless_dfu\pca10040e+
nRF5_SDK_15.3.0_59ac345\components\softdevice\s112\hex\s112_nrf52_6.1.1_softdevice.hex

merge generation SDK_APP.hex.

Download prompt error,Only SDK_APP.hex , the other will not go wrong.
But i use nRfgo Studio download successful.

Do I understand you correctly?

• If you program an other hex file (e.g. nRF5_SDK_15.3.0..\examples\peripheral\blinky\hex\blinky_pca10040.hex) using the nRF Connect Programmer app, it works fine
• If you program the SDK_APP.hex file using nRfgo studio, you don't experience any problems?

Some more questions:

• Could you explain how you created the hex files? Did you follow the steps in BLE Secure DFU Bootloader?
• Could you upload the SDK_APP.hex file as well? Then I can try to recreate your issue.
• What version of the Programmer app are you using?

Best regards,

Simon

yes,If program the SDK_APP.hex file using nRfgo studio, that is no problems.

Programmer  version V3.2.0.

SDK_APP.hex generation step:

nrfutil settings generate --family NRF52810 --application nrf52810_xxaa.hex --application-version 1 --bootloader-version 1 --bl-settings-version 1 bootloader_setting.hex

mergehex --merge s112_nrf52_6.1.1_softdevice.hex nrf52810_xxaa.hex nrf52810_xxaa_s112.hex -o output3to1.hex

mergehex --merge output3to1.hex bootloader_setting.hex --output sdk_app.hex

3716.sdk_app.hex

Do you have \ble_app_buttonless_dfu test_images(nrf52810)?

Thanks!

I was able to program the SDK_APP.hex file on the nRF52832 DK.

I see that you are using pca10040e projects (e-extension makes it possible to emulate nrf52810 on nrf52832), these are supposed to run on an nrf52832. Have you followed the steps under "Transferring emulated project" in this link in order to run in on an nrf52810?

If you are having more problems with this project, please ask, and I will help you.

Best regards,

I using pca10040e projects.

In the C/C++ preprocessor settings, remove the defines "DEVELOP_IN_NRF52832 " and "NRFX_COREDEP_DELAY_US_LOOP_CYCLES ".

The problem is still the same,Can you test with nrf52810?

Thanks！
