how should i debug the error during transfer when i init mmc card by send uboot command: mmc rescan ? this bug only when i init mmc card, SD card won't happen. Though this warning happened, but the response looks like OK.

thanks

在调查了更多网页后我得到了答案，

error during transfer表示从存储读取时发生超时错误。

1) 用于检查硬件侧 重新连接 CPU 板后可以重试吗？CPU 板的连接在交付过程中可能会松动。

2) 对于检查 S/W 方面，我想确认一下，您是否使用了我们的引导加载程序？Linaro 的引导加载程序的早期版本可能会根据情况发生这些事情。

如果您仍然有问题，则可能是 eMMC 问题。

此外，此错误代码（TIMEOUT）为-19
