7.8. Bootloader File System Support
U-Boot for the SMARC_sAMX8 provides support for FAT file systems. There are file system specific commands
available to list file system contents (fatls) and load a given file into board memory (fatload).
Example: Show/boot folder contents from SD card on carrier file system
=> fatls mmc 1:1 /boot
7.9. Bootloader Network Support
U-Boot provides support for both onboard Ethernet interfaces. The current interface can be selected by setting "ethact"
environment variable to either "FEC0" or "FEC1".
Board specific MAC addresses are read from EEPROM during startup and environment variables are set automatically.
In case EEPROM contents is missing or corrupted, a "random" MAC address will be set to "ethaddr"
In case that the current network interface is attached to a network providing a DHCP server, an IP address can be
gathered using "bootp" ord "dhcp" commands.
After that, a file from a tftp server can be copied to memory using the "tftpboot" command.
Example:
=> bootp
=> tftpboot ${loadaddr} <filename>
