【LeMaker Guitar试用体验】问题2 SD卡启动出错及还原方法

2016-1-27 01:11:43 11097

0 本帖最后由 gjianw217 于 2016-1-27 15:54 编辑按照官方教程，烧写Ubuntu Mate镜像文件，烧写也成功了，但没有使用多久，就出现启动不了的问题，当把SD卡插入PC后，也识别不了，不显示SD卡的盘符，不像其他的系统，可以显示盘符，进行格式化后重新烧写，故不知何解。一问题所在（解决方法在最下面） 1 使用的SD卡 2串口端显示的信息： Loaded environment from uEnv.txt Running uenvcmd ...

'pos' gives the file position to start loading from. If 'pos' is omitted, 0 is used. 'pos' requires 'bytes'. 'bytes' gives the size to load. If 'bytes' is 0 or omitted, the load stops on end of file. If either 'pos' or 'bytes' are not aligned to ARCH_DMA_MINALIGN then a misaligned buffer warning will be printed and performance will suffer for the load.

高增华 · 2016-1-27 09:05:04 沙发看log是mmc出问题，你的sd卡在别的板子上用过吗？类似拷贝了操作系统启动，sd卡直接启动系统对sd卡要求比较高滴！
