Getting Scr1 Running; Starting Up; Loading Binary Images To Memory - Syntacore SCR1 SDK Quick Start Manual

4. Getting SCR1 Running

4.1. Starting Up

1. Connect your host PC to the Arty's USB port (J10).
2. Open any terminal program. In the example below we use minicom terminal. Adjust its UART
parameters as follows:
◦ Bps/Par/Bits - 115200 8N1
◦ speed - 115200
◦ bits - 8
◦ stop bits - 1
◦ parity - none
◦ Hardware Flow Control: No
3. Initiate FPGA re-configuration process (push PROG button) or SOC internal circuitry reset (push
RESET button).
4. Terminal program should display SCR bootloader's banner and prompt:
