Development board is SAIL-IMX6Q from electric fish electrons into on Taobao. The core board is IMX6Q, based on NXP Cortex A9 architecture, clocked at 1.2GHz. I bought a 1G memory, 8G eMMC. Developer Edition features a very comprehensive, single Gigabit Ethernet, dual CAN, RS485, ISO7816, HDMI, PCIe, camera and 4G module interfaces. I had the time to buy this board that attracts a lot of features are quite useful in the process of learning in embedded development, not because there is no corresponding interface can not learn the appropriate knowledge. Developer Edition can run Linux and Android, performance is good.
In a week to get into the board, I followed step by step user's manual to learn the test code, complete test development board functions, and have a preliminary understanding on this board. There is still a lot to learn.
Ubuntu version with a 18.04LTS, Android version 6.0.1 configured build environment with the use of manufacturers to start learning. Because the compiler environment is too much trouble to build, not install a MDK can easily be resolved. Virtual machine version with VMware15.5.0, Win10 systems. Followed by a bunch of tools: SSH, VIM, SourceInsight, HyperTerminal, NotePad ++, Fastboot, Android ADB, QT and so many.
