Atmel Introduces SAMA5D2 Cortex A5 SoC with Extended Temperature Range, Lower Power Consumption

Today, the news broke out that Atmel will be bought by Dialog Semiconductor for about $4.6 billion. The Anglo-German company is little known as their main products are PMIC, audio and connectivity chips, but they’ve still managed to get the financing to purchase Atmel. But that’s not the purpose of the post today, and instead I’ll cover a new SAMA5 Cortex A5 SoC recently announced by the company, targeting industrial Internet of Things, wearables and point of sale applications. SAMA5D2 key features and benefits: ARM Cortex-A5 core running at 500MHz (785DMIPS). Floating point unit (FPU) for high-precision computing and accelerated data processing. 128KB of L2 cache for system performance Low power consumption Less than 150mW in active mode at 500MHz with all peripherals activated Less than 0.5mW in low power mode with SRAM and registers retention Sub 200µA in retention mode with context preserved New backup mode with DDR in […]

Linux 4.2 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 4.2 last Sunday: So judging by how little happened this week, it wouldn’t have been a mistake to release 4.2 last week after all, but hey, there’s certainly a few fixes here, and it’s not like delaying 4.2 for a week should have caused any problems either. So here it is, and the merge window for 4.3 is now open. I already have a few pending early pull requests, but as usual I’ll start processing them tomorrow and give the release some time to actually sit. The shortlog from rc8 is tiny, and appended. The patch is pretty tiny too. Go get it, Linus Some notable changes made to Linux 4.2 include: File systems New features for F2FS including per file encryption CIFS support SMB 3.1.1 (experimental) Cryptography – Jitter Entropy Random Number Generator, Chacha20 stream cipher and Poly1305 authentication (RFC7539),New RSA implementation.

Linux 3.18 Released

Linus Torvalds released Linux Kernel 3.18 last Sunday: It’s been a quiet week, and the patch from rc7 is tiny, so 3.18 is out. I’d love to say that we’ve figured out the problem that plagues 3.17 for a couple of people, but we haven’t. At the same time, there’s absolutely no point in having everybody else twiddling their thumbs when a couple of people are actively trying to bisect an older issue, so holding up the release just didn’t make sense. Especially since that would just have then held things up entirely over the holiday break. So the merge window for 3.19 is open, and DaveJ will hopefully get his bisection done (or at least narrow things down sufficiently that we have that “Ahaa” moment) over the next week. But in solidarity with Dave (and to make my life easier too 😉 let’s try to avoid introducing any _new_ […]

Beyond Debug Key Enables JTAG & UART Debugging, Supports OpenOCD

Beyond Semiconductor, a fabless semiconductor company based in Slovenia which develops their own 32-bit BA2x IP cores, has sent me one of their development tool, namely Beyond Debug Key supporting JTAG and UART interfaces either with BeyondStudio for the company’s BA2x processor, or the open source suite OpenOCD for other processors. Since I don’t have any Beyond Semi boards, I instead configured it, and quickly tried it with Atmel SAMA5D3 Xplained ARM Cortex A5 development board, and OpenOCD (Open On-Chip Debugger). The debug tool comes in the package above describing the key features of the kit: Performance Transfer rate in excess of 600 kB/s 30 MHz maximum JTAG clock Less than 20 μW power draw from target board Compatibility Fully compatible with Beyond BA2x processor family Access any 8-bit, 16-bit, 32-bit or 64-bit processors via JTAG Works with all JTAG compliant devices Software Support OpenOCD for access to a range […]
