gx6605s成功编译固件，但是无法使用，HDMI显示器没有任何反应 #27

Open siestina opened 2 years ago

siestina commented 2 years ago

如标题所示，按照https://c-sky.github.io/docs/quick-compile.html教程所示无法成功，make CONF=thead_610_compat_next_glibc_br_defconfig 完成后打开thead_610_compat_next_glibc_br_defconfig文件夹并进行编译成功了，但是写入u盘使用却没有成功开机。

这个配置是基于串口终端的

那要如何修改为HDMI终端或是使用串口终端加什么设备实现操作？试了一下用普通USB连接电脑开终端什么都无法显示。usb线接上后显示了CH340,然后得到了端口号，开putty的serial通信，一直没有信号，比特率都是默认的9600。随后试着刷了成品img，同样的方式连电脑尝试并没有成功。尝试复位以后有显示了，但是乱码

两个 micro-usb 口，一个是 Jtag 一个是串口 115200n8
