I finally learned how to use minicom to burn the system to my board in linux.

Finally, I learned how to use minicom to burn my system to my board-linux general technology-Linux programming and kernel information. Here is the details. Before that, I have burned the BIOS to NOR under WIN. If you want to write in LINUX, you can use the JFLASH tool.

Write process:
1. Connect J1 to NOR, enable minicom, and power on the board. A menu appears on the minicom terminal.
2. load flash vivi x, ctrl + a s and select the corresponding file supervivi.
3. load flash kernel x, ctrl + a s to download the kernel
4. loadyaffs-e root u: Download the root file system

I encountered some problems in the burning and writing process. I found some information on the Internet and finally got a solution:

1, Failure executing protocol, press any key to continue"
Cause of error: I am using the ubuntu system. It is said that the corresponding x protocol is not installed.
Solution: sudo apt-get install lrzsz

2, Transfer incomplete
Cause of error: the default settings of xmodem are not suitable.

Solution: set the following parameters. If the problem persists, increase the value until the problem persists.
Param set xmodem_inital_timeout 20000000
Param set xmodem_timeout 30000000
Param save
