Field name Command-specific description
GPM_STATUS A 1 in the least significant bit indicates an error occurred. All other
bits are reserved at this time.
GPM_BLOCK_NUM Indicates the number of GPM blocks available.
GPM_START_INDEX Indicates the size, in bytes, of a GPM block.
GPM_NUM_BYTES The number of bytes in the GPM_DATA field. For this command,
this field will be set to 0.
GPM_DATA No data bytes are specified for this command.
Example
A PLATFORM_INFO_REQUEST sent to a device with a serial number of 0x0013a200407402AC should
be formatted as follows (spaces added to delineate fields):
7E 001C 11 01 0013A200407402AC FFFE E6 E6 0023 C105 00 00 00 00 0000 0000 0000 24
Assuming all transmissions were successful, the following API packets would be output the source
node's serial interface:
7E 0007 8B 01 FFFE 00 00 00 76
7E 001A 91 0013A200407402AC FFFE E6 E6 0023 C105 C1 80 00 0077 0200 0000 EB
ERASE (0x01)
The ERASE command erases (writes all bits to binary 1) one or all of the GPM flash blocks. You can also
use the ERASE command to erase all blocks of the GPM by setting the GPM_NUM_BYTES field to 0.
Field name Command-specific description
GPM_CMD_ID Should be set to ERASE (0x01).
GPM_OPTIONS There are currently no options defined for the ERASE command.
Set this field to 0.
GPM_BLOCK_NUM Set to the index of the GPM block that should be erased. When
erasing all GPM blocks, this field is ignored (set to 0).
GPM_START_INDEX The ERASE command only works on complete GPM blocks. The
command cannot be used to erase part of a GPM block. For this
reason GPM_START_INDEX is unused (set to 0).
GPM_NUM_BYTES Setting GPM_NUM_BYTES to 0 has a special meaning. It indicates
that every flash block in the GPM should be erased (not just the
one specified with GPM_BLOCK_NUM). In all other cases, the
GPM_NUM_BYTES field should be set to the GPM flash block size.
GPM_DATA No data bytes are specified for this command.
ERASE_RESPONSE (0x81)
When an ERASE command request has been unicast to a node, that node sends a response in the
following format to the source endpoint specified in the requesting frame.
