I bought a learning board a few days ago. When I first used it, the running light program and the 4x4 key test program were both OK. Today, when I used it, only the 4x4 program was OK. The running lig...
2 boards are almost the same. 4G and 8G SD cards can boot the system on one, but only 4G can on the other. What is the reason? I have 2 minimal systems composed of imx53 using FSL. The only difference...
I majored in computer science and technology, and I have the basics of C++ and C# development, but I know very little about WinCE. I am studying hard now. I bought Meizu m8 some time ago, and I am goi...
