| SiFive E21 Core on ARTY FPGA Board |
| ================= |
| |
| - SiFive E21 Core IP v19p05 |
| - Digilent Arty Artix-7 100T Development Board |
| |
| |
| Required Tools |
| -------------- |
| |
| - OpenOCD |
| |
| |
| Setup |
| ----- |
| |
| The first step is to flash the SiFive E21 core on to the FPGA. To do this, |
| connect the ARTY board over USB and run: |
| |
| ``` |
| $ make flash-e21 |
| ``` |
| |
| It may display that many memory locations are incorrect. This didn't seem |
| to matter when I tried this. |
| |
| After that has finished, press the `PROG` red button on the top left of the |
| board. After a few seconds, one of the RGB LEDs should start pulsing colors. |
| It also prints over the serial connection. To see that, run: |
| |
| ``` |
| $ tockloader listen |
| ``` |
| |
| and select the option with the larger number. |
| |
| |
| Programming |
| ----------- |
| |
| To load a new kernel on to the board, run: |
| |
| ``` |
| $ make flash |
| ``` |
