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.

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?

I am trying to copy the Debian O/S installed on the Tinker Board 2S eMMC and the working software codes and settings between eMMCs to mass-produce them on the same 2S board. Please explain how.

Trying to create a program using python kivy in Tinker 2S tends to generate a rockchip error, no UI is created. Is it something that can be solved?

I made a mistake because I am a beginner. It was resolved.

Windows Putty -> Linux Putty is ok Linux Putty -> Windows Putty Write is failed Linux S0 Port -> Linux S4 Port is ok Linux S4 Port -> Linux S0 Port is ok

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.
