Bootloader problem (code = 3)

d.altmann

Hello,

I use the bootloader from the SDK SoftDevice 14.0.0.

I use the Laird module BL652 which have a nRF52832 component without external clock.

To compile the bootloader, I use the source code from : examples\dfu\bootloader_secure_ble\pca10040_debug\armgcc  (without secure key, it's more easy).

(I change the clock to the internal RC, I don't have button....)

To test, I load only the SoftDevice 5.0.0 and this bootloader.

The bootloader run and start. I use a tablet with the nRFConnect application.

I generate my application and have 3 type of file : xx.hex, xx.dat and xx.zip

I choose with nRFConnect the file (.hex+.dat or .zip only), the first commands are sent with good execution but, when nRFConnect want to send file, the nRFConnect application generate an error : "Remote DFU error : EXTENDED ERROR....Détails: Unknown command (Code = 3)"

I not find any information about this "Code = 3". This error code appears with the ZIP file or the HEX/DAT file (same error).

My J-Link RTT Viewer log is :

I send too an image from the nRFConnect application to see the problem.

For me, perhaps, the fault is when I generate the zip file with the nRFUtils :

          .\nrfutil.exe pkg generate example.zip --application application.hex --application-version 4 --hw-version 52 --sd-req 0x9D

I don't see where the error is comming.

Thank you for your helps.

Best regards,

Damien
