Note:When you are building a new image you need to set the image flag IMGSDBUS2 equal to 1 in order to use the new bus (sdbus2.dll). When IMGSDBUS2 is set to 1, sdbus2.dll is picked up during the makeimg process and is renamed to sdbus.dll in the generated image....
2.2 SD Bus Interface SD Bus Interface is an advanced 9-pin bus consisting of one clock line, one bi-directional command line, 4 bi-directional data line and 3 power lines. The bus is designated to operate at a maximum operating frequency of 200MHz depending on the capabilities of the Card...
3、Bus Speed Mode(总线速率模式) SD卡按总线模式来分,分为以下7种 1) 上图中SD卡图片上“I”表示支持USH-I(Ultra High Speed)的功能。USH-I表示的是可达最高104MB/sec的速度,注意不是实际的读写速度。可能是偶尔达到。 2) 上图中SD卡图片上“ ...
