@qtchamp said in Where to get the SDK:
I am using the free (Open source) version of QT. So kindly help me where I get the SQK for my board.
As @Pablo-J-Rogina said, there is no open-source SDK for your board.
Instead, you can download the Qt source code, and use your board's toolchain to compile the Qt libraries for your board.
