Linux 4.10 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has just released Linux 4.10: So there it is, the final 4.10 release. It’s been quiet since rc8, but we did end up fixing several small issues, so the extra week was all good. On the whole, 4.10 didn’t end up as small as it initially looked. After the huge release that was 4.9, I expected things to be pretty quiet, but it ended up very much a fairly average release by modern kernel standards. So we have about 13,000 commits (not counting merges – that would be another 1200+ commits if you count those). The work is all over, obviously – the shortlog below is just the changes in the last week, since rc8. Go out and verify that it’s all good, and I’ll obviously start pulling stuff for 4.11 on Monday. Linus Linux 4.9 added Greybus staging support, improved security thanks to virtually mapped kernel stacks, […]

Renesas SK-RZG1M Board Powered by R8A7743 Processor Gets Mainline Linux Support

Another board has gotten initial mainline Linux support recently, with Renesas SK-RZG1M starter kit board based on Renesas RZ/G1M dual core ARM Cortex A15 SoC with 2GB RAM, a SATA interface, HDMI, LVDS, AV Ethernet bridge, and more. Renesas SK-RZG1M starter kit board actually has the exact same features as Renesas R-Car M2 Porter board except for the processor: SoC – Renesas RZ/G1M (R8A7743) dual core ARM Cortex-A15 processor @ 1.5GHz with PowerVR SGX544MP2 3D GPU, Renesas 2D graphics processor System Memory – Dual channel 2GB DDR3 Storage – On-board 4 MB SPI, and 64 MB SPI, 1x SATA rev 3.1 connector, 1x SD card slot, and 1x micro SD card slot Video Output / Display I/F – HDMI (via ADV7511), and LVDS + touchscreen Analog Video In – ADV7180 video decoder with RCA jack, NTSC/PAL/SECAM autodetection Audio codec – AK4643EN with 3.5mm jacks for Line In and Line Out Connectivity […]

Linux 4.8 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has officially released Linux 4.8 last Sunday: So the last week was really quiet, which maybe means that I could probably just have skipped rc8 after all. Oh well, no real harm done. This obviously means that the merge window for 4.9 is open, and I appreciate the people who already sent in some pull requests early due to upcoming travel or other reasons. I’ll start pulling things tomorrow, and have even the most eager developers and testers hopefully test the final 4.8 release before the next development kernels start coming 😉 Anyway, there’s a few stragging fixes since rc8 listed below: it’s a mixture of arch fixes (arm, mips, sparc, x86), drivers (networking, nvdimm, gpu) and generic code (some core networking, with a few filesystem, cgroup and and vm things). All of it pretty small, and there really aren’t that many of them. Go forth and test, […]

Renesas GR-PEACH mbed Board Features RZ/A1H Processor with 10MB On-chip Memory

Renesas RZ/A1 ARM Cortex A9 processors were unveiled in 2013, and one of the differentiating feature was the large amount of on-chip SRAM with up to 10MB for RZ/A1H model. The following year, Renesas’ RZ/A1 professional development kit, and some RZ/A1H modules were launched, and I’ve now just seen a tweet about Renesas GR-PEACH development board that is mbed compatible, feature Renesas RZ/A1H processor, and happens to be pink. There are actually two models based on the same PCB: GR-PEACH normal without header, and a “WiFi” connector, and GR-PEACH Full with female headers and an Ethernet port. Both basically share the same specifications: SoC – Renesas RZ/A1H ARM Cortex-A9 Core @ 400 MHz with 10MB on-chip RAM, NEON and FPU, and 128KB L2 cache Storage – 8MB FLASH + micro SD slot Connectivity – Normal: Optional BP3595 WiFi module; FULL: 1x 10/100M Ethernet(Microchip LAN8710A); Both: Xbee connector (unpopulated) USB – […]

Renesas R-Car M2 Porter is a Linux Development Board for Your Car

So far, I always assumed development boards specifically designed for automotive applications would only be available to companies in the car or truck business, but as I wrote about FOSDEM 2016 schedule yesterday, I found out that one of the talk with cover FOSS software stacks that are available for automotive, and usable on hobbyist boards such as Raspberry Pi 2 and Minnowboard Max, but also on Renesas R-Car M2 Porter board specifically designed for automotive infotainment applications. Renesas Port board specifications: SoC – Renesas R-Car M2 dual core ARM Cortex-A15 processor @ 1.5GHz with PowerVR SGX544MP2 GPU, Renesas 2D graphics processor, and Multimedia Engine SH4A @ 780 MHz System Memory – Dual channel 2GB DDR3 Storage – On-board 4 MB SPI, and 64 MB SPI, 1x SATA rev 3.1 connector, 1x SD card slot, and 1x micro SD card slot Video Output / Display I/F – HDMI and LVDS […]

Renesas RZ/A1H Starter Kit and Emtrion DIMM-RZ System-on-Module Run Segger embOS RTOS or Linux with 10MB SRAM

Announced just about a year ago, Renesas RZ/A1 ARM Cortex A9 processor family can be used for human machine interface applications, and has the particularly to embed large amount of SRAM, especially the RZ/A1H series with 10 MB SRAM which allows the development of some applications without external RAM chip, lowering both board size and BoM cost. I’ve just come across a development kit dubbed “RZ/A1H Starter Kit”, and the just released Emtrion DIMM-RZ system-on-module both powered by Renesas RZ/A1H SoC. Renesas RZ/A1H Starter Kit+ (RSK) The development kit includes the mainboard, a 7″ TFT LCD (Optional), a detachable Colour LCD Board Pmod Compatible,a detachable AD Adjustment Shaft, Segger J-LINK Lite debugger, various connection cables, a power supply, a Quick Start Guide, and a DVD-ROM with documentation, ARM DS-5 IDE (with 32K code limit), KPIT GNU compiler for Cortex A9, Segger debugger drivers. and sample code.
