tftpGet –n0x400 –c<BOARD_IP_HERE> –f<path_and_filename>

–d/dev/enet2 –s<SERVER_IP_HERE>

sromWrite –d/dev/i2c0/srom/a8 –n400

Note The command lines shown above must be changed to reflect the specific board being

used. The VPD SROM device string passed to sromWrite needs to match the board. The

Ethernet device string needs to be appropriate for the board, as do the IP addresses being used.

It is very important to use the data file for the exact board to which the restoration is being

done. The –n (size) option should match the MOTLoad SROM size, which is defined by the Vital

Product Data Specification.

A.2.5 Editing VPD

The MOTLoad vpdEdit command allows VPD to be interactively edited. Ensure that the

proper safeguards have been put in place prior to editing VPD. For example, the VPD should be

both understood, and archived, prior to applying any changes. Incorrect VPD values can

prevent a board from reaching the MOTLoad command prompt. If this occurs, Safe Start, a

jumper option on some hardware products, should be used.

The edit session prompts the user with each byte currently in VPD, and the user has the option

of changing the byte by typing in a new value (a byte in hexadecimal), or the user can keep the

existing value by entering a carriage return. The meaning of each byte of data can be

determined by studying MOTLoad’s Vital Product Data Specification.

The following edit session entries have special meaning:

^ (caret) - reverse edit order. This is helpful if the byte needing to be changed has been passed

up during the edit session.

v (lowercase v) - edit in “normal” order again. This is handy after having used the ^, described

above.

. (period) - stop editing and query user as to whether edits are to be saved in SROM.

Here is an example of an edit session. Note that the addresses increment until the ^ is entered,

then decrement until the "v" is entered.
