With G35M/G35D it is possible to use Ethernet for remotely updating the binaries provided that the board is already booting from eMMC/SD.
Please refer section “File transfer using TFTP server” of software user manual for transferring files from server to board. Copy the files to eMMC/SD by accessing board via SSH.
Otherwise, the Kernel binaries alone can be booted using the Ethernet. Refer section “TFTP Boot” from software user manual.
