Copy eMMC between Tinker 2S

[Copy eMMC between Tinker 2S]

Thanks ! 

With your help, the hard copy was successfully completed.
By the way, after copying, I registered a static IP for the network, but the company Internet works normally, but external networks such as Google do not work normally. I wonder if this can happen.

[GRUB]

After installing the latest debian, I pressed shift, del, end, etc. during booting to connect to grub, but I couldn't connect. It is necessary to change the password of the root account. What could be the problem?

[How to set uart in 2S]

Trying to use ttyS0 port of UART0 of 2S.
I have tried settings such as baudrate setting, console, uart0=on, etc. in /boot/config.txt known in the forum,
 but reception to 2S works normally, but I do not receive a value from the receiver even though I write.
 Have there been any cases like this? I changed the communication line and changed the module.

 

I tested both Windows and Linux using the putty program.
