OKMX9352-C Single Board Computer
The default root user does not have a password set. To increase security, we can set a password with the password command. However, if the board is mass-produced, manually setting the passwords one by one will be very tedious. Therefore, we need a way to have the EVK automatically come with a default password after the re-burning.
Specific conduction is as follows:
- 1. After the board boots, set the password for the root user with the password command.
- 2. Two new files are created in the /etc directory: passwd and shadow.
- 3. Unzip the filesystem image into the development environment and put the above two files into the /etc directory, replace the previous file with the same name and unzip it again.
- 4. Re-burn this file system image to the EVK.
