How do I install or change an FPGA instrument on the ALPHA250?

You do not need to install the Koheron SDK or Vivado just to change the instrument running on the ALPHA250.

Precompiled instruments can be downloaded from the ALPHA250 reference designs page and uploaded directly to the board using its web interface.

You only need to set up the Koheron SDK and Vivado if you want to modify or compile an FPGA instrument yourself.

The Linux system is already installed on the SD card supplied with the board.
