Linux 3.19 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 3.19 yesterday: So nothing all that exciting happened, and while I was tempted a couple of times to do an rc8, there really wasn’t any reason for it. Just as an example, Sasha Levin used KASan and found an interesting bug in paravirtualized spinlocks, but realistically it’s been around forever, and it’s not even clear that it can really ever trigger in practice. We’ll get it fixed, and mark it for stable, and tempting as it was, it wasn’t really a reason to delay 3.19. And the actual fixes that went in (see appended shortlog) were all fairly small, with the exception of some medium-sized infiniband changes that were all reverting code that just wasn’t ready. So it’s out there – go and get it. And as a result, the merge window for 3.20 is obviously also now open. Linus Linux 3.18 improved performance of […]

Vonets VM300 Wi-Fi & Ethernet IoT Board with Mediatek MT7620 Runs OpenWRT

Mediatek MT760 is a recent Wi-Fi SoC found in some Nexx WT3020 routers, and WRTnode development board. Both run OpenWRT and costs $17 to $30 depending on the amount of flash, and ports with the former featuring two Ethernet ports, and the latter access to GPIOs. You could probably open the case of the Nexx routers and solder some wires to get access to GPIO, and you can hack an Ethernet cable for WRTnode, but another options could be Vonets WM300 kit that includes a board with Wi-Fi and Ethernet, a cable for USB / Ethernet connection, headers for GPIOs, and two external antennas for less than $30. An OpenWRT SDK is also provided for the kit. Specifications listed for VM300 board: Processor – Mediatek MT7260N MIPS processor @ 580MHz Storage – 4MB SPI Flash (option: 8MB/16MB) for firmware System Memory – 32MB or 64MB SDRAM Connectivity Wi-Fi Single band […]

LinkIt A-Core Packs Mediatek MT2502A SoC into a Tiny Module for Wearables

LinkIt ONE is a development board based on Meditak MT2502A SoC for wearables, and developed by SeeedStudio. With GPS, Wi-Fi, and GSM/GPRS connectivity, and a LiPo battery, it’s great to experiment IoT or wearable applications, but if you plan to launch an actual product, it could be nice to have a module, and built a baseboard around it. That’s exactly what SeeedStudio is working with LinkIt A-Core module. LinkIT A-Core module specifications: SoC – Mediatek MT2502AV ARM7 SoC @ 260 MHz with 32MB PSRAM and 32MB Flash on-chip. External Storage – 16M external Flash (MX25U12835F) Cellular Connectivity – GSM/GPRS quad-band 850/900/1800/1900MHz with RF7198 RF transmitter.

Fernvale Open Source Hardware IoT Board Based on Mediatek MT6260 SoC with GSM Connectivity

Andrew Huang (Bunnie), an hardware engineer, known for hacking the original XBOX, and more recently for Novena open source laptop, has decided it could be interesting to reverse-engineer Mediatek MT6260 processor, as in China, it’s difficult to get documentation, SDK, and tools if you don’t commit to purchase X chips, where X is a rather large number. He and others also checked whether their work could be open sourced legally, and assert their “fair use” rights to reverse-engineer hardware and firmware. And so Fernvale project was born both as a technical challenge and to make a point. MT6260 is a $3 ARM7EJ-S processor clocked at 364 MHz with 8MB built-in RAM, interfaces such as I2C, SPI, PWM, UART, as well as LCD and touchscheen controller, and audio codec, battery charger, USB, Bluetooth, and GSM support, which make the $6 Atmel MCU used in Arduino board look expensive. The main differences […]
