fel进不去了,请问怎么处理呢?多谢

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
