Freescale i.MX6 Resources: Development Boards, Documentation, Source Code and Tools

Reader “Mark” recently left a comment saying the NDA on Freescale i.MX6 resources was lifted and documentation and source code were now available for the platform. So it’s time for me to look into it, and provide an overview of Freescale i.MX6 features, list available development platforms, and have a closer look at the documentation, source code and tools for the platform. Freescale i.MX6 Processors In 2011, Freescale initially announced 3 processors in the i.MX6 series for consumer, industrial and automotive markets, but added 2 lite SoC in 2012, and there are now 5 members in the family: Freescale i.MX6SoloLite – Single Cortex A9 processor up to 1 GHz with 256KB L2 Cache, 32-bit DDR3 and LPDDR2 memory support, and 2D graphics accelerator (Vivante GC355 + GC320) Freescale i.MX6Solo – Single Cortex A9 core up to 1 GHz with 512KB L2 Cache, 32-bit DDR3 and LPDDR2 memory support, and 2D & […]

$199 GIZMO EXPLORER KIT – Embedded Development Kit Based on AMD G-Series G-T40E APU

I’ve just stumbled upon a low cost and open source embedded development kit featuring AMD G-Series G-T40E dual core APU that comes with the following: The Gizmo Board – A compact (10×10 cm) development board for powered by an AMD G-Series APU. The Explorer Board – An expansion I/O board providing an alpha-numeric keypad, a micro-display, and a breadboard area for prototyping and customization. Sage SmartProbe JTAG Development Tool – The kit includes the SmartProbe hardware and 20 hours of trial time use. Ethernet & USB Cables – The USB cable lets you connect the SmartProbe to your PC. The Ethernet cable is for networking connectivity, which can be used to access the SmartProbe as well. USB wall charger Power Supplyand Cable – A universal power supply for the Gizmo board, with a U.S.-standard cord. 6x standoffs with nuts Alpha-numeric keypad – To connect to the explorer board Installation DVD […]

Kontron ULP-COM-sAMX6i – Freescale i.MX6 Solo, Dual and Quad Computers on Module

Freescale i.MX6 series was first announced in January 2011, and there have been delays due to problem with the silicon, but now the i.MX6 processors are finally in mass production, and lots of different products are using this SoC. The latest product I found is ULP-COM-sAMX6i by Kontron which is a series of computers on module based on ULP-COM (Ultra Low Power) standard featuring Freescale i.MX6 solo, dual and quad processors. Those commercial and industrial grade modules target markets such as transportation, medical and military. Here are the technical specifications of the modules: CPU – Freescale i.MX 6 Single, Dual and Quad Core ARM Cortex-A9 @ 800 MHz (Industrial grade), 1 GHz and 1.2 GHz System Memory – Up to 2 GB DDR3 Storage – Optional onBoard NAND/eMMC up to 64GB Graphics / Video – Dual Display, HD 1080p Decode/Encode and 2D/3D acceleration Video Output Resolution Parallel LCD 18/24 bit […]

Learn How to Write a Driver for Linux 3.x With The Linux Driver Template

A Linux Driver Template (LDT) has been published to help new Linux kernel developers writing hardware device drivers. Constantine Shulyupin posted the Linux Driver Template (LDT) on the Linux mailing list in order to merge it into the mainline Linux kernel. The code can be used as as a starting point for new drivers, and shows how to use several Linux facilities such as  module, platform driver, file operations (read/write, mmap, ioctl, blocking and nonblocking mode, polling), kfifo, completion, interrupt, tasklet, work, kthread, timer, simple misc device, multiple char devices, Device Model, configfs, UART, hardware loopback, software loopback and  ftracer. This sample has been added to other device drivers samples in eLinux.org. And if you want to learn further there’s always the Linux driver bible: “Linux Device Drivers, Third Edition” which can be downloaded for free as PDF, although it’s for 2.6.10 kernel and many parts may not be up-to […]

XBMC for Linux on AllWinner A10 Devices? It Works! (Sort of)

Following the lack of support by AllWinner for the video engine libraries (CedarX), I had more or less given up on hope XBMC for Linux would ever run properly on AllWinner A10/A13 hardware. But recently, I found out some progress had been made using existing libs, and saw the Pengpod Tablet video showing XBMC running in Linux fairly smoothly. So I decided to cross-compile XBMC by following the instructions available at http://linux-sunxi.org/XBMC and trying to run it in Linaro ALIP 12.04 rootfs in my Mele A1000. Finally, I managed to cross-compile XBMC, but the performance was very poor in the GUI (6 to 12 fps) and I was unable to play videos and my serial console was flooded with messages like:

[Update: I managed to have XBMC Linux running & playing videos on Mele A1000 by using j1nx image (rootfs + kernel). I would first exhibit the exact same […]

Getting Started with 64-bit ARM Development: Hello World and Linux on ARMv8 Fast Models

At the end of last year, ARM announced ARMv8, the first ARM 64-bit ARM archtecture, and last week at ARM Techcon 2012, ARM announced the first ARMv8 cores: Cortex A53 and A57. But since there’s no silicon at the moment, what if you wanted to develop code running on ARMv8 before the hardware is available? The answer is: Fast Models, a Virtual Platform (VP) to accelerate software development. This is especially important for ARMv8 since hardware is not expected to be available for another year. In this post, I’ll first show how to run “Hello World!” in ARMv8 fast models, then we’ll run ARM Linux 64-Bit (Aarch64) in the virtual platform. ARMv8 Foundation Model In order allow the developer’s community to program for ARMv8 (Cortex A53/A57 cores), ARM has made ARMv8 Foundation Model, a virtual platform, available free of charge. This v8 Foundation model provides a basic ARMv8 platform environment […]

$100 Mele A1000G / A2000G Android Media Players with 1GB RAM and 8GB Flash

I’ve been asked by several people when there would be a Mele with 1GB RAM, well the time is now, with the Mele A1000G and Mele A2000G. Both appear to be based on the previous Mele A1000 and Mele A2000 set-top boxes, but feature 1 GB RAM and 8 GB Flash instead of 512 MB RAM and 4 GB Flash.
