再者说明下硬改背景，R141电阻挪到140的右端（看别人的帖子学的），然后电阻另一端飞线，vcc，gnd飞线，做了个三段开关以便控制spi和nand启动，nand刷的lede，spi16mB刷的原厂cfe，
看了下，怎么会有usb2.0和3.0，是不是说K3还可以外接usb2.0，用烧录器直接把原厂备份的cfe直接烧进了spi里，可是为什么启动的时候进不去原厂cfe，还有个疑问，如果说spi足够大（和nand同样大的内存）是不是可以直接刷系统，nand又是另一个系统，也就是说是双系统，通过三段开关控制启动方式
刚接触路由器硬改，小白一枚，工具烙铁，热吹风，CH341A烧录器都有，只是想学习下

你没发现还有sd么？这时自检时候测试的soc的io接口，soc本来有着这些接口，但是厂家未必会把接口做出来，当然你愿意都可以从cpu针脚引出来，进不去cfe你看看烧录、焊接、进入手法有没有问题，可以双系统，不是有人已经成功刷了tp的spi固件么

原来如此，为了测试我烧录是否正常，我专门把K2P金色拆了，换下存储器，烧录原厂备份系统，成功开机，之前刷的是A大的梅林，可以排除烧录的问题，焊接更没有问题了，正在排除问题
