Hi @Louis.Huang-Q
But In document of AG215, It only has “AB upgrade with Library way”.Can you send me document of AG215 about it.

Hi,

Please turn to your sales agent for the document “AG215S Series QuecOpen
A/B System Update Guide

For the stream method, I believe you will need to store the firmware to your own server.

Hi @Louis.Huang-Q. I got the struct of update.qwe package for streamway.Example:
image
I got that: [system] is partition name , sa515m-sysfs.ubi is image name.


In my project, i want to create A file in usrdata folder. Can I upgrade A file with stream way? If possible What is the name of this partition which involve usrdata folder?

Regards
Nam

Hi Nam,

Files in /usrdata will not be upgraded, you, as user, need to upgrade it from application side.

Louis

Thank @Louis.Huang-Q for your information
I understand that other folders same usrdata folder, right?
I want to choose a folder, which will store my file.txt. but this folder doesn’t easily lost the data. Because usrdata folder often lost the data when i use AB update and some folders just allow read the data.
Can you recommend for me?

Regards
Nam

Hi,

You can just create your own folder in /root directory, and mount with write-protected partition.
For other folders, there are often many different partitions will be mounted to them, so it’s difficult to recommand.

Thanks @Louis.Huang-Q

@Louis.Huang-Q So I can’t directly see sa515m-sysfs.ubi?

Hi Nam,

sa515m-sysfs.ubi is an image file, it’s in the firmware package, you cann’t see it from the directory.
