|
* Motorola S-Record Format:
|
|
*
|
|
* Motorola S-Records are an industry-standard format for
|
|
* transmitting binary files to target systems and PROM
|
|
* programmers. LSI Logic have extended this standard to include
|
|
* an S4-record containing an address and a symbol.
|
|
*
|
|
* The extended S-record standard is as follows:
|
|
*
|
|
* S<type><length><address><data....><checksum>
|
|
* S4<length><address><name>,<checksum>
|
|
*
|
|
* Where:
|
|
*
|
|
* type
|
|
* is the record type. Where:
|
|
*
|
|
* 0 starting record (optional)
|
|
* 1 data record with 16-bit address
|
|
* 2 data record with 24-bit address
|
|
* 3 data record with 32-bit address
|
|
* 4 symbol record (LSI extension)
|
|
* 5 number of data records in preceeding block
|
|
* 6 unused
|
|
* 7 ending record for S3 records
|
|
* 8 ending record for S2 records
|
|
* 9 ending record for S1 records
|
|
*
|
|
* length
|
|
* is two hex characters. This defines the length of the
|
|
* record in bytes (not characters). It includes the address
|
|
* field, the data field, and the checksum field.
|
|
*
|
|
* address
|
|
* is 4, 6, or 8 characters. Corresponding to a 16-, 24-, or
|
|
* 32-bit address. The address field for S4 records is
|
|
* always 32 bits.
|
|
*
|
|
* data
|
|
*
|
|
* Are the data bytes. Each pair of hex characters represent
|
|
* one byte in memory.
|
|
*
|
|
* name
|
|
* Is the symbol name. The symbol is terminated by a ','.
|
|
*
|
|
* checksum
|
|
* Is the one's complement of the 8-bit checksum.
|
|
*
|
|
* Example
|
|
*
|
|
* S0030000FC
|
|
* .

* S325000004403C0880018D08DD900000000011000026000000003C0880012508DC50C50000B401
|
|
* S32500000460C50100B8C50200BCC50300C0C50400C4C50500C8C50600CCC50700D0C50800D4FA
|
|
* S32500000480C50900D8C50A00DCC50B00E0C50C00E4C50D00E8C50E00ECC50F00F0C51000F49A

* S325000004A0C51100F8C51200FCC5130100C5140104C5150108C516010CC5170110C518011434
|
|
* .

|
|
* S70500000000FA
|
|
*
|
|
* The S0 record starts the file. The S3 records contain the
|
|
* data. The S7 record contains the entry address and terminates
|
|
* the download.
