You write embedded C and RISC-V assembly, connect software to memory-mapped peripherals, use timers and interrupts, inspect processor behavior, and run the work either in simulation or on an optional Digilent Nexys A7 FPGA board. It is a strong fit if you already understand basic programming, digital logic, assembly and computer architecture; it is not an ideal first programming or first hardware course.
The course is delivered by the Linux Foundation through edX. The authoritative description is on the Linux Foundation course page.

What LFD119x actually teaches
RVfpga is more than a standalone RISC-V processor. It is a teaching system-on-chip environment that combines a RISC-V core, embedded software, peripherals, simulation and FPGA deployment. That combination lets you follow a program from C source to assembly instructions, through processor execution, and out to a timer, display or interrupt-driven device.
The current Linux Foundation page identifies the processor as the VeeR EH1 Core. A 2023 launch announcement calls it the SweRV EH1 Core; these are different names used by official pages for the course’s core lineage, not evidence of two separate LFD119x offerings.
#1 Best Overall
“Industrial” describes the course’s use of a named, practical processor core in a complete SoC workflow. It does not mean that the class is an industrial certification or that you will design and tape out a commercial CPU.
Who should take it?
LFD119x is aimed at junior-level university students and above in computer science, electrical engineering and computer engineering, plus embedded and FPGA developers who want a closer connection between software and hardware.
Readiness checklist
- Write and debug basic C programs.
- Understand binary values, registers, addresses, stacks and pointers.
- Read simple assembly and follow control flow.
- Know the purpose of a processor pipeline at a high level.
- Understand memory and memory-mapped I/O.
- Have some digital-logic experience.
- Be comfortable using a terminal, Linux system or virtual machine.
If several of these are unfamiliar, begin with introductory C, assembly, digital logic or RISC-V material first. The official prerequisites explicitly include digital logic, a high-level language, assembly programming, the RISC-V ISA, processor microarchitecture, and memory and I/O systems.

The official outline has ten learning sections plus the verified-track examination. Here is what each part means in practice:
| Course section | What you do or learn |
|---|---|
| Welcome and installation | Prepare the tools, launch the environment and run an initial demonstration. |
| C programming with the RVfpga SoC | Compile and execute embedded C against the course’s SoC rather than a desktop operating system. |
| RISC-V assembly programming | Work directly with instructions, registers, control flow and low-level machine behavior. |
| RISC-V function calls | Study calling conventions, stack use and how functions pass values. |
| Mixing C and assembly | Make C and hand-written assembly interoperate in one program. |
| Peripherals and I/O | Access hardware through memory-mapped registers. |
| Seven-segment displays | Turn software writes into visible device output. |
| Timers | Use hardware timing rather than relying only on software delay loops. |
| Interrupts | Respond to hardware events with interrupt-driven code instead of constant polling. |
| Deeper VeeR core study | Relate ISA-level execution to core organization, configuration, counters and performance experiments. |
| Verified-track final examination | Complete the assessment associated with the paid verified path. |
This progression is the course’s main value: it connects programming, ISA concepts, peripherals and microarchitecture in one reproducible platform.
Tools and environments
The Linux Foundation lists several execution and inspection environments:
- Whisper: an instruction-set simulation environment.
- RVfpga-ViDBo: a Verilator-based simulation and visualization environment.
- RVfpga-Pipeline: a tool for examining pipeline behavior.
- RVfpga-Trace: a tool for inspecting execution traces.
- Ubuntu 22.04 virtual machine: a preconfigured environment intended to reduce installation differences.
- Digilent Nexys A7: the optional physical FPGA target.
The public course page does not specify every repository revision, compiler release or command. Use the current learner materials for those details rather than relying on an older tutorial or screenshot.

1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsDo you need a Nexys A7 board?
No. The official prerequisites say the course can be completed in simulation and identify the Nexys A7 as optional.
| Path | Advantages | Trade-offs |
|---|---|---|
| Simulation only | No board purchase; reproducible in a VM; excellent for C, assembly, peripherals, traces and core experiments. | No physical-board debugging, FPGA programming or real-device behavior. |
| Nexys A7 hardware | Runs programs on an FPGA and makes displays and peripherals tangible; useful for laboratory and hardware/software co-design work. | Requires the compatible board and setup, plus USB, power, programming and board-specific troubleshooting. |
Do not assume another FPGA board is a drop-in replacement. A different board can require a different bitstream, constraints file, clock setup or peripheral map. If you eventually want hardware, start in simulation and add the board when physical execution is central to your goal.
Operating-system and setup expectations
The course supports Linux, and the official page says most software is also supported on Windows and macOS. The supplied Ubuntu 22.04 virtual machine is the most controlled route, especially when native tool versions or host permissions become troublesome. “Supported” does not guarantee identical behavior across host operating systems, processor architectures or virtualization products.
A physical-board workflow can add USB-driver, cable, power, enumeration, board-revision, clock/reset and programming issues. Simulation avoids those failure modes, although it cannot reproduce every hardware-specific problem.
How the learning workflow fits together
- Launch the provided environment or install the supported tools.
- Run the initial RVfpga demonstration to confirm the setup.
- Compile and execute a small C program.
- Write and inspect equivalent RISC-V assembly.
- Examine function calls, stack behavior and C/assembly boundaries.
- Access memory-mapped peripherals.
- Drive a seven-segment display and work with timers.
- Replace polling with interrupt handlers.
- Use traces, pipeline views, performance counters and benchmarks to connect code with core behavior.
- Complete the verified-track examination if you chose the certificate option.
The exact commands and file layouts can change as the course materials evolve, so follow the current course environment for implementation details.

Difficulty and time commitment
edX describes LFD119x as self-paced and intermediate, with an estimate of 10 weeks at 2–4 hours per week. RISC-V International’s training directory gives a separate estimate of 12–16 hours. These figures can both be useful: one describes a paced study schedule, while the other is a compact content estimate. Your actual time will depend on your assembly background, whether you use the VM or native tools, and whether you troubleshoot a physical board.
Audit, certificate and price
The edX listing identifies an audit option and a paid verified track, with the final examination associated with the verified track. That page showed $149 USD when checked, while the RISC-V International training directory showed a separate $99 price signal. Prices, access windows, promotions, geography and account terms can change, so verify the checkout page before paying: edX course listing.
A verified certificate documents completion of the edX course. The available course descriptions do not establish it as a professional license, an industry certification or a guarantee of employment. Buy it when you need graded assessment or formal completion evidence; audit when the learning materials are the priority and a certificate has little value for your situation.

How LFD119x compares with other learning goals
| Your goal | Best fit | Why |
|---|---|---|
| First exposure to RISC-V | Introductory RISC-V training | Builds ISA and low-level foundations before the SoC and FPGA complexity. |
| Use C and assembly with peripherals | LFD119x | Combines software, memory-mapped I/O, timers, interrupts and simulation. |
| Design a CPU from RTL upward | “Building a RISC-V CPU Core” or a hardware-design laboratory | Those paths focus on implementing a core; LFD119x primarily uses and examines an existing SoC/core. |
| RISC-V application programming only | Programming or toolchain-focused training | LFD119x spends substantial time on hardware interfaces and microarchitecture. |
| Advanced Linux-on-RISC-V | Embedded-Linux or operating-system training | LFD119x is a bare-metal architecture and SoC course, not principally an OS course. |

Limitations and common mistakes
Assuming “RISC-V” means beginner level
The prerequisite burden is real. Without assembly, digital logic and memory/I/O knowledge, setup and fundamentals may consume more time than the RVfpga work itself.
Confusing simulation with hardware deployment
Simulation is sufficient for the course, but it cannot teach cable, programming, clock, reset or board-enumeration problems. Hardware adds realism and troubleshooting, not a mandatory prerequisite.
Expecting permanent tool compatibility
VM images, simulators, FPGA tools and course interfaces can change. Recheck current materials rather than copying commands from an old review.

The current course page says VeeR EH1, while the launch post says SweRV EH1. Treat this as an official naming difference and follow the terminology in the current materials.
Final recommendation
Choose LFD119x if you want a practical bridge between RISC-V software and processor hardware, especially C/assembly interoperability, peripherals, interrupts, simulation and optional FPGA execution. Begin with simulation unless a physical board is central to your course or project.
Choose another course first if you are new to programming or digital logic, want only application-level RISC-V development, or specifically want to implement a CPU core from scratch. For everyone else with the prerequisites, LFD119x offers a unusually concrete way to see how an ISA, an industrial-style core, an SoC and real or simulated hardware fit together.
