f1c100s拿来我只需要连接flash的第1和第4引脚就可以烧录
但是我自己烧录进去一个自己编译好的uboot后，就无法通过上面这种方式进入到fel了
看论坛可以通过TF卡的方式进入
我按教程使用下面这个命令进行烧写
dd if=fel-sdboot.sunxi of=/dev/sdb bs=1024 seek=8 但是只要插上TF启动，连uboot都进不去
使用
sunxi-fel -l命令也找不到对应的设备
请问下各位大佬应该怎么处理呢？
不甚感激
下面是uboot启动的打印日志

@哇酷小二
这个方法是不是烧写到tf卡，然后在tf卡上启动吗？
主要是我不太想在tf卡上启动
我想在spi上烧录

已经解决了，之前使用串口，然后短接flash1和4脚，没成功
现在我换成usb线，然后短接flash1和4脚就可以啦哈哈哈哈哈
