Hello,

I made a 'pca101000_usb_s140_ble_debug' configuration to see if I could replicate the issue, but it seems to work fine with both transports in my case. Could you please try with my bootloader to see if it works for you as well?

USB and BLE bootloader:

devzone.nordicsemi.com/.../nRF5_5F00_SDK17.1.0_5F00_pca10100_5F00_usb_5F00_ble_5F00_debug.zip

Hello,

I make my secure bootloader to debug mode following 'pca10100e_usb_debug'.
And I got "<debug> nrf_dfu_flash: Flash write failed (0x3)".

Packet length is always 1024(0x400) and this is multiple of 4. Last packet length is 932 and multiple of 4 too.

Hello,

The 'pca10100e_usb_debug' project is placed together with the other secure bootloader projects in SDK/dfu/secure_bootloader/. Is it a requirement to have a open bootloader where you can upload unsigned images?

Hello,

I using SDK 17.0.2. And this SDK DFU open bootloader examples are for pca10056 and pca10059. How can I find pca1011e_usb_debug??

I using command like this.
nrfutil pkg generate --application my.hex --application-version-string 1.0.1 --hw-version 10000 --sd-req 0x0100 --key-file my_private_key.pem my_dfu_package.zip

And I check bin file in zip.

Hello,

To confirm it's not something with your setup, could please try USB DFU with the 'pca10100e_usb_debug' example and see if it fails in the same way?

[quote user=""]Try to USB DFU by nrfutil, it works download dfu file. Checked by -vvvv option and first 5 hex values and last 5 hex values are exactly same.[/quote]

Have you checked if these values match the hex values in your binary image?

Best regards,

Vidar
