Tips for repairing SD cards Because the plastic shell is very thin, the standard size SD card is easy to damage, if you put the case in your pockets or without protection, the cards will easily break down. Sometimes the little write-protection switch will fall off, allowing the

It will install SYSLINUX in safe mode, so it may take a long time to boot the system, and it is unnecessary for SD to install

capacity problem. I understood it! Note that the function name here is the number of read sectors, and the actually returned value is the capacity of our card. Pay attention to it here. 1. First, check the code U32 SD_GetSectorCount (void) {u8 csd [16]; u32 Capacity_KB, Capacity_MB; u8 n; b2csize; // obtain CSD information. If an error occurs during this period, returns 0 if (SD_GetCSD (csd )! = 0) return

driver bus driver and client driver are provided by Microsoft, but not by Microsoft itself. It looks like it was developed by bsquare. The code of the bus layer is located in C:/wince500/public/common/oak/Drivers/sdcard/sdbusdriver. (C:/wince500 is the directory where you install wince ). The client code is located in C:/wince500/public/common/oak/Drivers/sdcard/sdclientdrivers. Microsoft has two client drivers (Bluetooth and sdmemory ). The following describes the main functions of each layer.
