Author: Wai Bu This is not a complicated thing to start with, but to be simple and clear, I really don't know how to organize it. After all, words are different from sound language. I hope the simple things don't make me talk too complicated. ARM board system files typically have three--bootloader (uboot), Kernel (uimage), and Root file systems (ROOTFS). After power on the arm board, start in order of Uboot->kernel->rootfs. Since there are a variety of storage media on the board, three files can

Ubuntu installation record for Bay Trail-T X86 Tablet I tried to install Ubuntu on two atom tablets one after another. I encountered some problems and made a simple record here, so that I could give a reference to a friend who made similar attempts. For the first time, install ubuntu 15.04x64 on Cobi cube iwork7. Iwork7 configuration: Z3735F + 2g ram + 32G eMMC; The uefi of iwork7 is 32-bit. Therefore, the bootia32.efi file is required to create an in

. We use two versions of mobile phones, W-mode with TD, come over a few days to find TD's mobile phone faster than W, and TD 28 seconds to get up, but W but to 34 seconds, asked the driver of the colleague, W and TD and no difference, so in addition to the modem is not the same, the other is the same. Looking for a day, still no result. From the log, it's only slow, that's slower, only in the process of scanning the package, the w+gsm takes about 6 seconds, and td+gsm only takes about 3 seconds

Flash Road Map Obviously, Flash is one of the technologies that will accompany us for a while in the future. The new storage technology evolved from this technology also came to light. Just three months ago, the mmca (multimediacard Association) and jedec solid state Technology Association agreed to choose emmc, as a

, also known as thumb drives and/or pocket drives. In general, flash memory has five obvious advantages: (1) small size, which may be further reduced over time; (2) low power; (3) high storage capacity, over time, it will increase exponentially; (4) it will hardly be destroyed (no moving parts) If encapsulated properly; (5) it will become cheaper.
