OTA DFU UART Error 0x07

[amarin]

Hi,

I am currently trying to run the secure_bootloader example given the in the sdk 15.2.0. I am currently having trouble as when I try to send the file, the error shown in the picture occurs. I am trying to upload the blinky_mbr test file application given in the example hex files.

Any help is greatly appreciated!

Hi, 

You should use  --sd-req 0x00 while geneating the package for the mbr application as 

nrfutil pkg generate --hw-version 52 --sd-req 0x00 --application-version 1 --application blinky_pca10056_mbr.hex --key-file private.pem FW.zip
