我用的是全志A64的开发板，进入fel模式后我运行run.bat
这个run.bat的内容
"win32\sunxi-fel.exe" version
set BOARD=m64
"win32\sunxi-fel.exe" -v -p spl %BOARD%\sunxi-spl.bin
"win32\sunxi-fel.exe" -v -p write 0x44000 %BOARD%\bl31-a64-h5.bin
"win32\sunxi-fel.exe" -v -p write 0x4a000000 %BOARD%\u-boot.bin
"win32\sunxi-fel.exe" -v -p write 0x40080000 %BOARD%\Image
"win32\sunxi-fel.exe" -v -p write 0x4fa00000 %BOARD%\sun50i-a64-bananapi-m64.dtb
"win32\sunxi-fel.exe" -v -p write 0x4fc00000 %BOARD%\boot.scr
"win32\sunxi-fel.exe" -v -p write 0x4fe00000 %BOARD%\initramfs.uimg reset64 0x44000
运行完run.bat后串口输出如下

请问什么原因导致内核不去在fel里启动，他找不到emmc和sd卡怎么不去找fel

uboot的逻辑是不进fel，除非你改usb的代码，我记得aodzip的uboot是可以的
