Hi,AndreasF:

I create the .zip file by cmd like this "nrfutil pkg generate --hw-version 52 --application-version 1 --application application.hex --sd-req 0x8C --key-file private.key 1227_2_update.zip",it contains an application hex file.

the bootloader is compiled by the example project bootloader_secure,I changed some address cause my device is 52832 QFAB;

The version of softdevice is 12.3, S132 3.0.0.

The error does not occured every times,I just repetition it three times ,but I can update success most of time.
