* Linux Operating System (this guide uses Ubuntu 16.04)
+
For now follow the guide from the [https://github.com/ARIES-Embedded/riscv-on-max10/blob/master/GettingStarted.md repository].
−
* Utility Software (git, make, python)
 
−
* [http://fpgasoftware.intel.com/?edition=lite Quartus Prime]
 
−
* A [[Spiderboard_SoM|SpiderSoM]] or MX10<sup>[[Installing OpenOCD#MX10 Hardware Issue|[note]]]</sup> with atleast 8K LE, [[Spiderboard_Baseboard|SpiderBase]], optionally [https://shop.aries-embedded.de/tools/pmod/302/pmod-8ld?c=88 LED Pmod]
 
−
* One of the following:
 
−
** [[Installing OpenOCD|OpenOCD]]
 
−
** USB Blaster and Quartus Programmer

== Installing VectorBlox ORCA Core and RISC-V Tools ==
 
−
 
 
−
* Download the source from [https://github.com/VectorBlox/orca https://github.com/VectorBlox/orca] using git.
 
−
*: This guide uses the install locations ''/opt/orca/'' and ''/opt/riscv/'', you can substitute them if you wish.
 
−
* Open a terminal window and run:
 
−
*: '''$''' <nowiki> git clone https://github.com/VectorBlox/orca.git /opt/orca </nowiki>
 
−
*: '''$''' cd /opt/orca/tools/riscv-toolchain/
 
−
*: '''$''' export RISCV_INSTALL="/opt/riscv"
 
−
*: '''$''' ./build-toolchain.sh
 
−
*:: Info: This may take a while.
 
−
* Finally, add the RISC-V tools to your path. Open ''.profile'' in your home directory with a text exitor and add the line:
 
−
*: PATH="/opt/riscv/bin:$PATH"
 
−
* After updating the path variable you may need to logout and login again or run the following command in the terminal:
 
−
*: '''$''' source ~/.profile

−
 
 
−
* Download the [https://downloads.aries-embedded.de/products/MX10/software/demo/20190604_mx10_spider_riscv_freertos.zip RISC-V & FreeRTOS Example] and unpack.
 
−
* Then choose either RISC-V or RISC-V & FreeRTOS and run make.
 
−
* Open a terminal window and run the commands:
 
−
*: '''$''' wget <nowiki>https://downloads.aries-embedded.de/products/MX10/software/demo/20190604_mx10_spider_riscv_freertos.zip</nowiki>
 
−
*: '''$''' unzip 20190604_mx10_spider_riscv_freertos.zip
 
−
** For the RISC-V standalone demo:
 
−
**: '''$''' cd mx10_spider_riscv_freertos/riscv
 
−
** Or for RISC-V with FreeRTOS:
 
−
**: '''$''' cd mx10_spider_riscv_freertos/riscv_freertos
 
−
*: '''$''' make
 
−
* This will create the ''bootrom.mif'' (Memory Initialization File) in the subfolder ''out''.
 
−
* Copy the ''bootrom.mif'' to ''mx10_spider_riscv_freertos/quartus_mx10'' or ''mx10_spider_riscv_freertos/quartus_spider'', depending on which module you use.
 
−
*: '''$''' cp out/bootrom.mif ../quartus_spider

== Quartus Prime Project ==
 
−
 
 
−
* Open Quartus Prime and load the project under ''mx10_spider_riscv_freertos/quartus_mx10'' or ''mx10_spider_riscv_freertos/quartus_spider''
 
−
* Open Device Settings (Assigments -> Device) and select your FPGA, the default FPGA the MX10 project is the 10M08DAF256C8G FPGA and for the SpiderSoM project the 10M08SAU169C8G FPGA.
 
−
* Open '''Assignments -> Settings -> IP Settings -> IP Catalog Search Locations''' and add the search path to ORCA.
 
−
*: If ORCA was installed under ''/opt/orca/'' then type in as search path ''/opt/orca/**/*'' and click on the ''Add'' button.
 
−
[[File:quartus_setting_iploc.png|700px|Type in the search path and then click on ''Add''.]]
 
−
* (Optional) Launch Qsys Platform Designer and open ''qsys.qsys''
 
−
** (Optional) Under System Contents, double-click ''onchip_memory2_0'' and under memory initialization provide your bootrom.mif file. Per default the bootrom.mif in the quartus folder will be used.
 
−
** (Optional) Save and Generate the Qsys system.
 
−
[[File:qsys-ram-init.png|900px|Setting the memory initialization in Qsys Platform Designer]]
 
−
* Compile the project and program it onto the FPGA using either [[Getting Started: Quartus Prime & OpenOCD#Programming via OpenOCD | OpenOCD]] or [[Getting Started: Quartus Prime & OpenOCD#Programming via USB Blaster| USB-Blaster]].
 
−
 
 
−
 
 
−
After programming:
 
−
 
 
−
* If the red or orange LED on the module starts blinking once per second, the FPGA was programmed successfully.
 
−
* If the green LED on the module starts blinking once every two seconds, the RISC-V Core and its firmware is working.
 
−
* PMod J2 will output a binary counter.
 
−
* You can use the UART of the FPGA by using standard tools such as picocom:
 
−
*: '''$''' sudo picocom -b 115200 /dev/ttyACM0
 
−
** Every character written is looped back and should be displayed on the terminal.
