Hi.

Could you provide more information?

How did you create the .zip file?

What does it contain?

What bootloader are you using?

Which SoftDevice are you using?

Which SDK are you using?

Best regards,

Andreas

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.

Hi.

I think that there might be some timing issue. Can you try to debug and see where you end up when you get the error?

Best regards,

Andreas
