Motorola S-Record.
Motorola S-record is a file format, created by Motorola, that conveys binary information in ASCII hexadecimal text form. This file format may also be known as SRECORD, SREC, S19, S28, S37. It is commonly used for programming microcontrollers, EPROMs, and other types of programmable logic devices. In a typical application, a compiler or assembler converts a program's source code (such as C or assembly language) to machine code and outputs it into a HEX file. The HEX file is then imported by a programmer to "burn" the machine code into a ROM, or is transferred to the target system for loading and execution.

Construct an S-Record by parsing a string.
|
static |
Construct S-Records by parsing a file.
Returns a vector with one element per line of input. Lines that did not contain an S-Record or which had trailing characters other than white space are reported as SRecord objects of type SREC_NONE and an error message.
|
static |
Size of address in bytes.
The address is encoded in twice as many ASCII characters.
| size_t Rose::BinaryAnalysis::SRecord::encodedSize | ( | ) | const |
Size of encoded S-Record in characters.
If an error was encountered when parsing this S-Record (!error().empty()) then the size reported by this method will likely be only the size up to the point where the error was encountered.

Load S-Records into a memory map.
The specified S-Records are loaded into the memory map. If createSegments is true then a minimal number of segments are created to hold the S-Record data, otherwise the destinations must already be mapped or a MemoryMap::NotMapped exception is thrown. When new segments are created they are given access permissions specified by accessPerms and the name specified by newSegmentNames (or "S-Records"). Access permissions are not consulted and do not cause errors when writing S-Record data into the map.
| uint8_t Rose::BinaryAnalysis::SRecord::checksum | ( | ) | const |
Compute the checksum for the data.
An S-Record checksum is the 1's complement of the sum of address and data bytes modulo 256.
|
static |
Dump a memory map as S-Records.
All data in the specified memory map is dumped to the specified output stream. The addrSize should be 2, 3, or 4 to indicate 16-, 24-, or 32-bit addresses. The output is not prefixed with an SREC_HEADER record nor terminated with SREC_COUNT or SREC_START records. An std::runtime_error is thrown if an address in the memory map cannot be encoded in the specified addrSize number of bytes. Returns the number of records emitted.
