Backing up the current firmware from U-Boot over serial can take hours. Booting a working Linux image for backup purposes is not always an option. Using the tftpput command in U-Boot is the fastest and easiest way. tftpput will upload the contents of a memory region to the TFTP server. The IP address of the server is stored in the serverip variable. Usage: tftpput <memaddr> <length> <filename> Example for a complete flash backup of an o2 Box 6431 (VGV7510KW22): VGV7510KW22 # tftpput 0xB0000000 0x1000000 o2boxbackup.bin Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> |
