How to upload a cross-compiling program into the EC312

FAQ
1
I have built my first program with the Cross-compilation tool zip package: gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu.tar.gz and now I need to upload it from my Ubuntu machine to the EC312.
How can I do this?

Hi,

1. Download the x86_64 platform cross compilation toolchain for EC312:
wget https://developer.arm.com/-/media/Files/downloads/gnu-a/9.2-2019.12/binrel/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu.tar.xz
2. Decompress cross compilation toolchain:
tar Jxvf gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu.tar.xz
3. Export environment variables:
export PATH=$PATH:<Tool chain path>/bin
4. Cross compile application programs
5. Files can be transferred via FTP using SSH backend commands (configured as an FTP server on the PC, EC312 uses FTP commands to connect and retrieve applications)；Applications can also be deployed in bulk through the DeviceLive platform：
