AM335x Beaglebone Black eMMC 启动进uboot执行 saveenv时出错,
部分log如下:
OMAP SD/MMC: 0, OMAP SD/MMC: 1
initcall: 80803005 (relocated to 9fdd0005)
Card did not respond to voltage select!
mmc_init: -17, time 13
** Bad device mmc 0 **
请问各位大侠,这个是什么原因呢?
硬件板子没有nand flash,改成了emmc.通过uboot将MLO 和 uboot的mmc命令烧写到emmc后,uboot可以运行起来,是不是emmc初始化的问题?要如何操作呢?

请问您启动用的也是emmc吗?会不会是格式化的问题。
