13.3.7.6 Response packetThe responses are carried using the same command packet format wrapped with framingpacket data. Types of responses include:• GenericResponse• GetPropertyResponse• ReadMemoryResponseGenericResponse: After the Kinetis Bootloader has processed a command, thebootloader will send a generic response with status and command tag information to thehost. The generic response is the last packet in the command protocol sequence. Thegeneric response packet contains the framing packet data and the command packet data(with generic response tag = 0xA0) and a list of parameters (defined in the next section).The parameter count field in the header is always set to 2, for status code and commandtag parameters.Table 13-15. GenericResponse ParametersByte # Parameter Descripton0 - 3 Status code The Status codes are errors encountered during the execution of acommand by the target (Kinetis Bootloader). If a command succeeds, thena kStatus_Success code is returned. Table 13-40, Kinetis BootloaderStatus Error Codes, lists the status codes returned to the host by theKinetis Bootloader for KLx3 ROM.4 - 7 Command tag The Command tag parameter identifies the response to the command sentby the host.GetPropertyResponse: The GetPropertyResponse packet is sent by the target inresponse to the host query that uses the GetProperty command. The GetPropertyResponsepacket contains the framing packet data and the command packet data, with thecommand/response tag set to a GetPropertyResponse tag value (0xA7).The parameter count field in the header is set to greater than 1, to always include thestatus code and one or many property values.Table 13-16. GetPropertyResponse ParametersByte # Value Parameter0 - 3 Status code4 - 7 Property value. . . . . .Can be up to maximum 6 property values, limited to the size of the 32-bitcommand packet and property type.Functional DescriptionKL27 Sub-Family Reference Manual , Rev. 5, 01/2016192 Freescale Semiconductor, Inc.
