FOSDEM 2024 schedule – Open-source embedded, mobile, IoT, robotics, RISC-V, etc..

FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where thousands of developers meet in Brussels on the first week-end of February to discuss open-source software & hardware projects. FOSDEM 2024 will take place on February 3-4 with 880 speakers, 818 events, and 66 tracks. Although I won’t attend, I’ve created a virtual schedule like every year with sessions most relevant to the topics covered on CNX Software from the “Embedded, Mobile and Automotive” and “Open Hardware and CAD/CAM” devrooms, but also other devrooms including “FOSS Mobile Devices”, “ Energy: Reimagining this Ecosystem through Open Source”, “RISC-V”, and others. FOSDEM Day 1 – Saturday, February 3, 2024 10:30 – 10:55 – Screen Sharing on Raspberry Pi 5 Using VNC in Weston and Wayland with the Yocto Project and OpenEmbedded by Leon Anavi In 2023, embedded Linux developers received eagerly awaited news: […]

LuckFox Pico Rockchip RV1103 Cortex-A7/RISC-V camera board comes with an optional Ethernet port

LuckFox Pico is a small Linux camera board based on the Rockchip RV1103 Cortex-A7 and RISC-V AI camera SoC and offered with an Ethernet port in a longer version of the PCB called LuckFox Pico Plus. Both models come with 64MB RAM (apparently embedded in RV1103), a microSD card slot for storage, a MIPI CSI camera connector, a USB Type-C port for power, and a few through holes for expansion through GPIO, I2C, UART, and so on. LuckFox Pico and Pico Plus specifications: SoC – Rockchip RV1103 with Arm Cortex-A7 processor @ 1.2GHz, RISC-V core, 64MB DDR2, 0.8 TOPS NPU, 4M @ 30 fps ISP Storage MicroSD card slot LuckFox Plus only – 1Gbit (128MB) SPI flash (W25N01GV) Camera – 2-lane MIPI CSI connector Networking (LuckFox Pico Plus only) – 10/100M Ethernet RJ45 port USB – USB 2.0 Host/Device Type-C port Expansion – 2x 20-pin headers with up to 24x […]

X1501 Pico SoM – MIPS, Linux in a 16x16mm module

We’ve just written about the Notkia phone repurposing Nokia 168x phones with a new PCB featuring an Ingenic X1000E MIPS processor running mainline Linux, but it turns out the developer (Reimu NotMoe, CTO of SudoMaker) has also designed the X1501 Pico SoM, a tiny 16×16 system-on-module equipped with Ingenic X1501 MIPS system-in-package (SiP). The module can be that small because the single-core 1GHz Ingenic 1501 SiP embeds 8MB LPDDR, as well as apparently a 16Mbit NOR flash that stores stripped-down versions of U-boot and the Linux kernel, plus a minimal, busybox-based rootfs. X1501 Pico system-on-module specifications: SoC – Ingenic X1501 MIPS32r2 processor @ 1GHz, a MIPSr2 real-time core @ 300 MHz (not shown in datasheet), 8MB LPDDR and 16KB tightly coupled SRAM, 16Mbit NOR flash Castellated holes with USB 2.0 OTG, I2C, SPI, SDIO and DVP, analog mono audio output & digital microphone input EFUSE based Secure Boot Power Management […]

Western Digital Made RISC-V Linux & BusyBox Boot on Sipeed Maix Go Board

The other day we wrote about Getting Started with Embedded Linux on RISC-V in QEMU emulator and noted that Linux capable RISC-V hardware is currently fairly expensive. We also mentioned there was work on porting uCLinux to Kendryte K210 RISC-V processor on boards such as Sipeed Maix board. The processor only comes with 8MB RAM, and does not feature an MMU (Memory Management Unit) so what you’d be able to do on the board would be limited, and for instance, a desktop environment is clearly impossible on the platform. NOMMU support also requires some extra work, and in Linux 5.4 we saw only of the changes was “SiFive PLIC IRQ chip modifications, in preparation for M-mode Linux”. The slide above is extracted from the “RISC-V NOMMU and M-Mode Linux” presentation by Damien Le Moal, Western Digital at the Linux Plumbers Conference 2019 last September. It explains M-mode support is better […]

Embedded Linux Conference & Open Source Summit 2019 Schedule

In the last few years, I covered the Embedded Linux Conference and IoT Summit schedules since both were happening at the same time and in the same location. But the Linux Foundation have recently announced the Embedded Linux Conference will combine with the Open Source Summit, so the IoT Summit appears to have been phased out. The full schedule for the events taking place on August 21 – 23, 2019 at the Hilton San Diego Bayfront, USA, has also been released, so I’ll create a virtual schedule with some of the sessions most relevant to this blog. Wednesday August 21, 2019 11:30 – 12:05 – What’s New with U-Boot? by Simon Glass, Google LLC U-Boot is a widely used bootloader in embedded systems. Many users are unaware of the wide feature-set of U-Boot, particularly features added in the last few years. This talk aims to bring users (and prospective users) […]

Baikal T1 MIPS Processor – The Last of the Mohicans?

CNXSoft: Guest post by Blu about Baikal T1 development board and SoC, potentially one of the last MIPS consumer grade platforms ever. It took me a long time to start writing this article, even though I had been poking at the test subject for months, and I felt during that time that there were findings worth sharing with fellow embedded devs. What was holding me back was the thought that I might be seeing one of the last consumer-grade specimen of a paramount ISA that once turned upside-down the CPU world. That thought was giving me mixed feelings of part sadness, part hesitation ‒ to not do some injustice to a possibly last-of-its-kind device. So it was with these feelings that I took to writing this article. But first, a short personal story. Two winters ago I was talking to a friend of mine over beers. We were discussing CPU […]

How to Run Linux on RISC-V with QEMU Emulator

RISC-V open-source architecture is starting to become more and more interesting thanks to the growing RISC-V hardware & software ecosystem, and with the recent release of HiFive Unleashed, we even have a board capable of running Linux. The only problem: it costs $999. But luckily, it’s possible to experiment with Linux on RISC-V without extra hardware, just using your current PC. Imperas offers a commercial solution working on both Windows and Linux that relies on busybear-linux RISC-V Linux root filesystem comprised of busybox and dropbear SSH server. The rootfs also works with QEMU, so I tried it in Ubuntu 16.04. The instructions on Github are quite easy to follow. My computer is powered by an AMD FX8350 processor coupled with 16GB RAM, and the whole process took around 2 hours, so better use the fastest computer possible. It also requires around 26 GB of storage on your build machine. First, […]

Banana Pi M2 Ultra Allwinner R40 Development Board with SATA & GbE Sells for $46

Allwinner A10 and A20 processors have been quite popular in the past since they could handle Fast or Gigabit Ethernet and SATA natively, included decent multimedia capabilities, and were found in low-cost hardware such as Cubieboard 2 or MeLE A1000. Since then we’ve had a few boards with SATA using newer and faster processors without SATA IP, meaning it was usually implemented using a USB 2.0 to SATA bridge leading to mediocre to average performance depending on the implementation and selected bridge. Allwinner R40 is the successor of Allwinner R20 with a faster quad-core Cortex A7 processor, but keeping Gigabit Ethernet, SATA, and most features of its predecessor. The good news is that Banana Pi has now launched the promised M2 Ultra development board based on the new processor for $45.80 + shipping on Aliexpress (Total for me: $48.35). Banana Pi M2 Ultra specifications: SoC – Allwinner R40 quad-core ARM […]
