SD Card write protection How to remove the solution:
Step 1, about the SD card write protection How to remove the problem, you can use the disk repair program to repair the SD card. Open My Computer, locate the SD card and right-click on it, select "Properties"-"Tools", click "Start Error Checking", in the pop-up "Che
This paper illustrates the method of Android2.3 to realize the automatic mounting of SD card and U disk. Share to everyone for your reference, specific as follows:
The SD card is always not mounted automatically when porting the android2.3 on the s3c6410 platform. Check the relevant information, know in android2.3 is the Vold program is responsible for checking the kernel of the Sysfs file system, found th
the kernel. This Bootstrap mode of bootloader is usually used in system development and updating.
In the development phase of embedded systems, the existing bootloader download guide methods can be divided into the following types based on different loading methods:
① Download the kernel from the host to the target board through the Ethernet port to enable the software system;② Download the kernel from the host to the target board through the serial port to start the software system;③ Directly
The SD card has been watched for two days. It is mainly because the tested card capacity is incorrect, so I have been searching for the reason and finally found out that the total ratio is just a problem with the unit, maybe it's because I haven't touched SD before, so I don't know much about some of the registers. Everything is a new start. Compare this Register Manual, understand the program, and modify t
ZYNQ Linux Linaro System image made SD card boot 0. OverviewZynq generated uboot and normal arm device is not the same, Zynq belongs to two secondary boot uboot and then by the Uboot boot the kernel, probably means that there is a mechanism inside the ZYNQ, the mechanism can not be modified by the dial switch to control the startup mode, For example, starting from an SD card or booting from QSPI, the
Familiar with SD/MMC-related registers, which can assist in understanding the protocols. So this article will introduce the SD/MMC-related registers?
1. SD card internal architecture
Before getting familiar with SD/MMC registers, let's take a look at the internal architecture of the

Android SD card driver and standard Linux under the SD card driver does not seem to be much different, here on the high-pass Android 2.3 to represent, to briefly analyze the Linux under the SD card driver. Because the small brother's technology is limited, the analysis of the wrong place, please correct me, y
The SD card uses a fat (File Allocation Table) file system and does not support access mode and permission control. The SD card is suitable for storing large-sized files or files without the need to set access permissions.Android simulators support SD card, but the simulator does not have the default SD card.

Hippocampus simulator is an Android simulator, we can simulate the setup of the phone's SD card, then if the SD card mirrored file capacity directly to expand, you need to find a way, SD card expansion needs to occupy the computer above the hard disk space, it is also mainly in a large hard disk operation.
So before you adjust, be careful to back up the data in

Causes of SD card data loss
Why are SD card files lost? Is the opening method incorrect? Or cannot the SD card be read by the computer? In fact, there are various factors that may cause SD card data loss. Only by figuring out the status and causes can we better solve the problem, including:
Factor 1: plug-in failure
