8.2.3.22 Serial Hexmate Option

The -serial=specs option will store a particular HEX value sequence at a fixed address. The usage of this option is:
-serial=Code[+/-Increment]@Address[+/-Interval][rRepetitions]
where:
  • Code is a hexadecimal sequence to store. The first byte specified is stored at the lowest address.
  • Increment is optional and allows the value of Code to change by this value with each repetition (if requested).
  • Address is the location to store this code, or the first repetition thereof. Its interpretation is based on the addressing value (see Addressing Hexmate Option).
  • Interval is optional and specifies the address shift per repetition of this code.
  • Repetitions is optional and specifies the number of times to repeat this code.

All numerical arguments are assumed to be hexadecimal values, except for the Repetitions argument, which is decimal value by default.

Note that this option inserts data into the output HEX file, thus, to prevent a conflict, you must ensure that the locations where this data is to be placed are not already populated by other data from a HEX file or from another option.

For example:
-serial=000001@EFFE
will store HEX code 0x00001 to address 0xEFFE, assuming an addressing value of 1.
Another example:
-serial=0000+2@1000+10r5
will store 5 codes, beginning with value 0000 at address 0x1000. Subsequent codes will appear at address intervals of +0x10 and the code value will change in increments of +0x2.
