Dear Support team,

Our company is currently using the HelperBoard T507 with Linux 18.04 and the QT 5.12 framework for development. Previously, we downloaded the SDK from the following link:
http://down.szbaijie.com:8088/helperbox/
However, this URL is no longer accessible. Additionally, the "Resource Download" section (http://szbaijie.f3322.net:8088/v2.5/sources/) in the personal account displays a blank page.

Could you please provide a valid download link for the SDK?

In our development process, we have been using the Qt 5.12 version provided by your team. However, it lacks some essential libraries that we require. We attempted to build our own version of Qt 5.15 using qmake.config for linux-generic-g++ with the necessary libraries but were unsuccessful.

Could you clarify whether a custom qmake.config was used for HelperBoard T507? If so, would it be possible for you to share it with us?

Lastly, we would like to inquire whether there are any plans to update the Linux OS to a newer version (20.04 or 22.04) in the near future.

We appreciate your assistance and look forward to your response.

Best regards,
Sergey Demchuk
