imx6dl uimage文件过大怎么解决

杨帆！起航！

我最近用imx6dl安卓，修改内核后烧写 uImage 文件，现在是5M，以前是3M，错误如下

In:    serial
Out:   serial
Err:   serial
Net:   got MAC address from IIM: 00:00:00:00:00:00

您好，这个问题应该比较简单，从你输出的信息看得出来，你的内核头已经被正确识别，但是加载内核的时候，可能受到某个变量的限制，没有将5M内核全部拷贝进来，拷了个烂尾残缺内核，所以做CRC校验通不过

楼主你好，请问你这里是写到SD卡上还是emmc上呢？是不是你的u-boot参数没有设置正确，导致找不到kernel image，建议你查看一下内核启动参数设置。
还有楼主这里使用的是哪个版本的BSP，板子是自己设计的吗？

烧写到sd卡没事，烧写到emmc上出错，以前是emmc4.5，现在换成了emmc5.0，错误如下

网上说改掉mmc.c的6换成7.但是出现以下错误

小智MM求帮助！！！烧写工具为：Mfgtools-Rel-13.01.00_ER_MX6DL_UPDATER
BSP为：L3.0.35的内核，安卓系统
