nRF5340 OTA fails with Mcu Mgr Error: 10 Group: 1 after interrupted upload

[lexologe]

Hi,

I get a Mcu Mgr Error: 10 Group: 1, when I

1. start OTA on Android smart phone
2. interrupt during upload by disabling BLE on the phone
3. enable BLE again
4. retry OTA upload

This is the corresponding error message:
<err> mcumgr_img_grp: Image upload inspect failed: 10

Do I need to wait longer until the error will go away 

or

do I need to do anything other then retrying directly?

I found out that if I run `kernel reboot cold` on the Zephyr shell, then there is no more Error 10 and the upload will start as expected.

Thanks, Alex

Hello,

Could you tell me which version of the SDK you are using here, and which Nordic chip or DK you are trying with? Could you share the entire log (including the error message) here?

Kind regards,

Yes, sure. I am using NCS SDK v2.6.1 and I am using a custom PCB based on the nRF5340 DK

I am not sure if I am allowed to share the entire log but I can share the part that contains the messages that come up when I start OTA.

And the following messages show up for a successful OTA:
(the errors should be okay because the network core update is not in flash)
