Ken Tough, principal engineer at Intrinsyc Software, discusses Linux on eMMC at Embedded Linux Conference 2012. Abstract: Embedded devices are increasingly choosing eMMC instead of raw NAND flash as their main storage, for increased independence from component vendors and changing storage densities. This presentation examines Linux configuration for eMMC, how to effectively measure your eMMC performance, and tips to improve it. Topics covered include: filesystem bearing on MMC/SD performance, IO scheduler configuration, and optimal partition layout. Target audience is embedded systems developers or users interested in getting the most out of their eMMC/SD card. You can also download the presentation slides on elinux.org.

Toshiba is currently showcasing the Toshiba AirFlash – a new Wifi-Enabled SDHC card – at IFA 2011 in Berlin (2-7 September 2011) The card features an embedded wireless LAN chip that allows it to both transmit and receive files wirelessly. The FlashAir is reportedly the world’s first SDHC memory card with embedded wireless LAN functionality to meet the SD Memory Card Standard. Previously other SD cards such as Eye-Fi allowed Wi-fi connectivity, but the Eye-Fi could only transmit files from a camera directly to another Wifi device, the FlashAir can receive and transfer by using point to point connection and a router is not needed. The FlashAir can be fully configured thanks to a configuration file located in the SD Card, so that you can select the IP of the SD Card, the wifi security settings such as WEP, WPA, WPA2… and more. The Toshiba FlashAir will be sampled starting […]
