I am hitting a strange error only with this project where the app_update.bin file is 239672 bytes in size.
The error I get is when I try to send it to the board with newtmgr. I get Error: 3.
I tried to add debug for the newtmgr, the information I got was not comprehensive.
I saw on the Internet that sometimes it might be the file size, but did not see what was the size limit.
Does anyone has got similar error? was it related to size ?
