У меня нет устройства fpga, есть только бриджи и fpga manager в /sys/class/, да и то с другими немного именами и параметрами, чем приводится в инструкциях. An FPGA, instead, becomes whatever hardware you need. It can morph into a microprocessor, a game console, a real-time IP switch or encryption device, an antitheft server or anything else you can imagine. The only limits are that your circuit cannot require more transistors or external pins than those physically present on the chip, and it can't go faster than the intrinsic propagation delay from gate to gate. That said, modern FPGAs are powerful enough to let you squeeze several Linux-compatible microprocessors, like the Nios, the PowerPC or the Microblaze, inside them and still have lots. 21 июля г. Как помигать светодиодом на Zynq FPGA (ПЛИС) с помощью Linux используя отладочную плату Zybo вместе с sysfs или /dev/mem. В данной статье будет рассмотрено несколько способов мигания светодиодом, в принципе небольшое пособие по использованию портов ввода вывода из Linux. Теория.  Когда закончиться перейти в синтезис "Open synthesized design". По умолчанию, снизу должна открыться вкладка I/O Ports, если её нет, в правом верхнем углу следует выбрать I/O Planning  все драйверы в Linux предоставляют доступ к объектам посредством файлов. Для того чтобы работать с GPIO, используя этот интерфейс нужно записывать и считывать данные из файлов.

The world of FPGAs has traditionally been full hardwarf closed-source mysteries: designs have long been crafted using expensive, multi-gigabyte vendor toolsand the inner working of vendors' hardware and software have remained closely guarded secrets. In this series, I'll 'show off' a variety of hardware you can use to develop your own designs using open-toolchains— and hopefully help people to get a feel for the ecosystem.

These designs were intended by Lattice to fill the "low-cost, low-complexity, and low-power" markets — but many of these FPGAs are extremely capable.

While boards with open hardware fpga linux newer UltraPlus FPGAs are less common, the boards that exist seem extremely hardare — and there's a open hardware fpga linux of community focus on these devices. These FGPAs are significantly more capable than the iCE40 family, but relatively few development boards featuring these FPGAs have made their way to market; and these development boards tend to be more expensive.

The Xilinx 7-series don't quite have an mature open-source toolchain yet — but the Project X-Ray reverse-engineering effort is getting closer every day. Open hardware fpga linux open-source flow is currently capable of routing designs using the FPGA's basic logic, but the bitstream format and corresponding hardware still needs more reverse-engineering to enable more FPGA features, and the toolchain is opsn yet mature.

Still, the future is looking bright for 7-series inclusion; and an open-toolchain for these chips would bring higher-end FPGAs under the open-toolchain umbrella. It's my hope that before too open hardware fpga linux, this post can open hardware fpga linux in a comparison between the 7-series and the Lattice offerings. Kate Temkin is a hardware hacker and low-level engineer; and the software lead over at Great Scott Gadgets.

Her passion is working on educational technologies; and tools to help you do cool things. What might steer you towards an iCE40 UltraPlus: If you're looking to implement a system with both software and gateware components, a the iCE40 UltraPlus is perfect for developing designs with simple soft-processors. What might steer you towards another FPGA: The UltraPlus 's internal logic "fabric" is slower than its siblings in Open Hardware Linux Linux the HX series — which often means that the same design will run at a lower maximum frequency.

Designs that need fast logic more than they need buffer space may open hardware fpga linux better on an HX variant. Several commercial products also offer ECP5 environments suitable for some projects; and several general-purpose open-source boards are currently in crowdsourcing.

This is expected to change soon; as more of those boards move out of crowdsourcing.
