ARM Unveils Cortex-R52 ARMv8-R CPU Core for Safety-Critical Systems

ARM has introduced their very first ARMv8-R real-time 32-bit CPU core with Cortex-R52 designed for safety-critical applications in the automotive, industrial and health-care markets. It has been designed to address higher workloads with increased performance (up to 35%) compared to Cortex-R5 processor. The processor should be used in systems capable of fulfilling IEC 61508 SIL 3 and ISO 26262 ASIL D functional safety requirements. ARM explains the new processor address both random errors for example bit flipping from radiation, and systemic errors more related to software or design faults. The latter can be addresses with the right development processes, including following aforementioned functional safety standards, but random errors require some extra hardware features such as ECC memory, or dual core lock step processors, where instructions are run on two processors simultaneously and results compared. Normally, the whole software stack must be validated and certified on safety-critical systems, even for part […]

Orange Pi One Development Board Sells for $3.69 Shipped (Promo)

[Update: Sorry the promo is over, and price is back at $13.79] Last time, we had a promo for Orange Pi PC for $8.57 on GearBest, and it was legit, but quantity limited, so not so easy to get.

U-Boot Now Supports UEFI on 32-bit and 64-bit ARM Platforms

Intel/AMD x86 based computers now boot via a standard UEFI binary, which can load grub2, allows you to update the command line as needed, or select different version of the Linux kernel. On ARM everything is a little more complicated and messy, as bootloaders such as U-boot need to support different configurations formats. Alexander Graf has been working on implementing UEFI support in U-boot, and it’s now supported by U-boot mainline and enabled by default for 32-bit and 64-bit ARM platforms, but not x86-64 (yet). That means you should now be able to boot any ARM boards supported by mainline U-boot through UEFI. Alexander gave a presentation about his work at an openSUSE event in June, and demonstrated u-boot with UEFI, and GRUB2 support with an openSUSE image running on a Raspberry Pi board.

Intel Smartwatches are Hot! So Hot, They May Burn Your Skin

Low power in constrained spaces is a tricky business, even for ARM based SoCs with the Qualcomm 810 overheating saga a few months ago. Now it’s time for Intel to feel the heat, as the company has has to recall Basis Peak smartwatches / fitness trackers due to potential overheating causing skin burns. Josh Walden – senior vice president and general manager of the New Technology Group at Intel Corporation – stated: On behalf of the Basis Science team, I want to personally apologise for this situation, we know that many of you love using your Basis Peak watches and have made them part of your daily lives, and we are very sorry for the disruption this will cause you, we had hoped to update the software on your watch to address the problem, unfortunately, despite our best efforts, we aren’t able to develop such a solution without completely compromising […]
