请问大佬 RTL8188FTV 插上后如下报错是哪里出问题了呢?

按照这篇教程做下来也是这个问题,其实就是.config没有配置正确导致的。

make menuconfig 这个不用执行
替换成下面这条就好了

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- linux-licheepi_nano_defconfig

Linux6.8.2内核成功启动

HoWi 说:

@LLCC
我大概对了下你杜邦线的颜色,貌似是串口接错了吧?Rx<->Rx, Tx<->Tx?


是的,现在可以正常输出了 :D

找到问题了,是usb转ttl接线接错了~ 连的tx和tx ,rx和rx 🤡

应该是 TTL的TX ->nano的U0RX、RX ->nano的U0TX。

晕哥 说:

接USB看能否进入FEL烧录模式,如果能进入,说明没有运行程序。

谢谢晕哥,卖家说板子是已经烧录过Xboot的,不知道是不是这个原因。

现在拔掉tf卡短接 flash 1,4 引脚可以正常进入fel模式

按照这篇文章 又重新编译烧录了Uboot,串口还是无输出

abc@ubuntu:~/LicheeNano/u-boot$ sudo sunxi-fel -p spiflash-write 0 u-boot-sunxi-with-spl.bin

usb转ttl连了TX、RX,板载microUSB也连了电脑

不知道是哪里出了问题

回复: 5

问题描述:

tf卡启动,Xterm串口不显示任何东西,重新插拔也不行。

问题补充:

纯小白,某宝购入荔枝派nano打算入坑,参考该视频 用Win32DiskImager烧录了官方提供的image,到重新上电这一步无任何输出。

各位大佬这是什么原因导致的,之前复刻了v3s也是串口无法通信。

typec连接电脑是可以识别到串口的,但是sunxi-fel检测不到

第一次画板子,<原理图>是参考v3s_lcd的,各位大神帮忙分析下是啥原因('ヮ')


当时画原理图RESET引脚直接接地了,现在从3v3接了飞线过去~但还是不行
不知道哪里焊接还有问题
UART0的 TX RX 都是3.3v,ch340/typec的D+是3v,D-是0v,
24M晶振IN端电压是1.53v,OUT端是1.33v
