OpenWrt 23.05 released with MbedTLS by default, Rust packages, over 1,790 supported devices

OpenWrt 23.05

OpenWrt 23.05 open-source Linux operating system for routers and resource-constrained headless embedded systems has just been released with over 4300 commits since the release of OpenWrt 22.03 a little over a year ago. The new release now supports over 1790 devices or about over 200 new devices compared to the OpenWrt 22.03 release with notable new targets including the ipq807x target for the Qualcomm IPQ807x WiFi 6 SoCs, the mediatek/filogic subtarget for the Mediatek Filogic 830 and 630 SoCs, and the sifiveu target for the HiFive Unleashed and Unmatched RISC-V development boards. OpenWrt 23.05 switches from wolfSSL to MbedTLS as default because the latter has a much smaller footprint and offers a more stable ABI (application binary interface) and LTS releases, but it does lack support for TLS 1.3, so users who need the latter may still switch to wolfSSL if needed. Another highlight of the new OpenWrt release is […]

Ollie v2 USB to UART/CAN/RS485/RS232 converter gets USB-C port, plastic enclosure, and more (Crowdfunding)

USB-C to UART, CAN Bus, RS485, and RS232 converter

Ollie v2 is an improved version of the Ollie USB to isolated UART, CAN Bus, RS232, and RS485 converter that gains a USB-C port, a plastic case, the ability to set the voltage from the target board, and various other minor improvements. Like the first version, the Ollie v2 is a portable tool designed for hackers and field engineers that allows them to work with a single device instead of a bunch of USB converters, each handling a single protocol, and isolation makes sure the host, such as a laptop, is protected from high voltages. Ollie V2 specifications: Serial chip – WCH CH344 quad-serial port chip (instead of XR21V1414 in the first design) Host interface – USB Type-C port Isolated interfaces (all with ESD protection) 2x UART ports up to 6 Mbps with 1.8/3.3/5 V or target voltage levels (set by slide switch) CAN 2.0A/B up to 1 Mbps bus […]

Sipeed Tang Mega 138K Pro Dock features GOWIN GW5AST FPGA + RISC-V SoC

Sipeed Tang Mega 138K Pro Dock

Sipeed has launched another FPGA board part of their Tang family with the Tang Mega 138K Pro Dock powered by a GOWIN GW5AST SoC with 138K logic elements as well as an 800 MHz AE350_SOC RISC-V hardcore unit, and featuring a PCIe 3.0 x4 interface, DVI Rx and Tx, two SFP+ cages, a Gigabit Ethernet RJ45 port, and more. We’ve previously seen companies like AMD (Xilinx) and Microchip produce FPGA SoCs with hard cores such as the Zynq Ultrascale+ family (4x Cortex-A53) or the PolarFire MPSoC (4x 64-bit SiFive U54 RISC-V cores), but it’s the first time I see GOWIN introduce an FPGA + RISC-V SoC, as all the previous parts that came to my attention were FPGA devices. Sipeed Tang Mega 138K Pro Dock specifications: System-on-Module – Sipeed Tang Mega 138K Pro SoC FPGA – GOWIN GW5AST-LV138FPG676A with 138,240 LUT4 1,080 Kb Shadow SRAM (SSRAM) 6,120 Kb Block SRAM […]

SiFive unveils P870 high-performance core, discusses future of RISC-V

SiFive Hot Chips 2023 x86 vs Arm vs RISC-V

SiFive has just given a presentation at Hot Chips 2023 introducing the new high-performance P870 RISC-V core and its automotive equivalent the P870-A core, plus discussing RISC-V in general, its previous generation RISC-V cores, and what to expect going forward. SiFive has not officially announced the P870 and P870-A cores just yet, so most of the information we have from the English-speaking Internet is from ServeTheHome who managed to get some presentation slides, but this is also corroborated by various Chinese sources on Baidu and Guokr. SiFive P870 and P870-A The P870 and P870-A RISC-V cores are new cores from the SiFive Performance family compatible with the RISC-V RVA23 profile and succeeding the SiFive P670 core. The SpecINT2k6 benchmark reports 17 points per GHz on the P870 compared to 13.2 points per GHz for the P670 (comparable to the Arm Cortex-A78) or about a 29% higher performance at the same […]
