Hi, I downloaded freedom-e310-arty-1-0-2.mcs from SiFive web. After the fpga programming is completed, press ‘PROG’ button to reload and get the following output.

SiFive E-Series Software Development Kit ‘demo_gpio’ program.
Every 1.5 second, the Timer Interrupt will invert the LEDs.
(Arty Dev Kit Only): Press Buttons 0, 1, 2 to Set the LEDs.

My question is: How did you merge an elf and bit file into an mcs ?
