Zsun SD111 Is Now “Officially” an Hackable Wireless Flash Drive

Zsun SD11x are Wi-Fi flash drives for 8 to 128 GB eMMC, alternative to Sandisk or Kingston. Yesterday, I soldered the UART pins to Zsun SD111 (8GB) flash drive to access the serial console, but I did not manage to enter the terminal as it was password-protected. I posted my results anyway, as I was convinced I would get some clever ideas from my readers, some of which appeared to be a little time consuming, but Zoobab offered a simple solution that consisted in changing the boot parameters, by replacing /sbin/init by /bin/sh. The first step is to interrupt the boot by pressing space or another key, in order to access U-boot. Now we can check the U-boot environment ar7240> printenv bootargs=console=ttyS0,115200 root=31:02 rootfstype=jffs2 rw init=/sbin/init mtdparts=ar7240-nor0:64k(u-boot),64k(u-boot-env),6720k(rootfs),1216k(uImage),64k(NVRAM),64k(ART) bootcmd=bootm 0x9f6B0000 bootdelay=4 baudrate=115200 ethaddr=0x00:0xaa:0xbb:0xcc:0xdd:0xee ipaddr=10.168.168.1 serverip=10.168.168.10 stdin=serial stdout=serial stderr=serial ethact=eth0 Environment size: 361/65532 bytes Let’s keep everything the same, except the init, […]

Imagination Technologies Introduces PowerVR Series7 GPUs with Up to 512 Cores, Virtualization Support

Imagination Technologies has announced a new PowerVR Series7 GPU architecture that will be used in their high end PowerVR Series7XT GPUs delivering up to 1.5 TFLOPS for mid range and high-end mobioe devices, set-top boxes, gaming consoles and even servers, as well as their low power lost cost PowerVR Series7XE GPUs for entry-level mobile devices, set-top boxes, and wearables. PowerVR Series7 GPU, both Series7XT and Series7XE GPUs, can achieve up to a 60% performance improvement over PowerVR Series6XT/6XE GPUs for a given configuration. For example a 64-core PowerVR7XT GPU should be up to 60% faster than a 64-core PowerVR Series6XT clocked at the same frequency, with all extra performance due to a different and improved architecture. Some of Series7 architectural enhancements include: Instruction set enhancements including added co-issue capability, resulting in improved application performance and increased GPU efficiency New hierarchical layout structure that enables scalable polygon throughput and pixel fillrate […]

Rayeager PX2 Development Board Features Rockchip PX2 Dual Core Cortex A9 Processor

Rockchip has apparently discreetly released a PX2 SoC with a dual core Cortex A9 processor @ 1.4 GHz coupled with a Mali-400MP4 GPU, that on the surface looks extremely similar to their RK3066 SoC. Unfortunately, at first, I could not find much details about the processor itself, but Chipspark have introduced Rayeager PX2 development board based on the new Rockchip processor, with 1 to 2 GB RAM, an 8GB eMMC flash, and various ports including a SATA 2.0 interface. Rayeager PX2 specifications: SoC – Rockchip PX2 dual core Cortex A9 @ 1.4 GHz with Mali-400 MP4 GPU System Memory – 1 to 2 GB DDR3@400MHz Storage – 8 GB eMMC flash, micro SD slot, and SATA 2.0 interface for 2.5″ and 3.5″ hard drives (the latter may require external power supply) Video Output – HDMI, and VGA up to 1080p, , and LCD interface Video Input – 1x CVBS input […]

Android 5.0 Lollipop Source Code Pushed to AOSP

As Nexus 6 smartphone, Nexus 6 tablet, and Nexus Player have now started to ship, Google has pushed Android Lollipop to AOSP (Android Open Source Project), as well as images for Nexus 4, Nexus 5, Nexus 7 (2012 and 2013), and Nexus 10. You’ll soon be able to retrieve the source code with the following command lines [Update: I still can’t use the lollipop-release branch to retrieve the code, so instead you can use android-5.0.0_r1 tag for Nexus 9, or android-5.0.0_r2 tag for Nexus Player / Android TV]: repo init -u https://android.googlesource.com/platform/manifest -b android-5.0.0_r1 repo sync Currently repo init fails with: error: in init -u https://android.googlesource.com/platform/manifest -b lollipop-release –repo-url=https://gerrit.googlesource.com/git-repo –repo-branch=stable: revision lollipop-release in manifests not found But everything should come online soon. In the meantime, you could still browse the code. Anyway that means Android 5.0 images for mini PCs, TV boxes and other devices will hopefully be available in […]
