798 | * ascending address order in the fw file. | |

802 | * with a certain address to make it identiable. | |
76e3e7c4 | 803 | * |
d8950599 | 804 | * Here's the SREC format that the fw should have come from: |
76e3e7c4 KR |
805 | * S[37]nnaaaaaaaaddd...dddcc |
806 | * | |
807 | * nn - number of bytes starting with the address field | |
808 | * aaaaaaaa - address in readable (or big endian) format | |
809 | * dd....dd - 0-245 data bytes (two chars per byte) | |
810 | * cc - checksum | |
811 | * | |
812 | * The S7 record's (there should be only one) address value gets | |
d8950599 KR |
813 | * converted to an S3 record with address of 0xff400000, with the |
814 | * start address being stored as a 4 byte data word. That address is | |
815 | * the start execution address used for RAM downloads. | |
76e3e7c4 KR |
816 | * |
817 | * The S3 records have a collection of subformats indicated by the | |
818 | * value of aaaaaaaa: | |
819 | * 0xff000000 - Plug record, data field format: | |
820 | * xxxxxxxxaaaaaaaassssssss | |
821 | * x - PDR code number (little endian) | |
822 | * a - Address in load image to plug (little endian) | |
823 | * s - Length of plug data area (little endian) | |
824 | * | |
825 | * 0xff100000 - CRC16 generation record, data field format: | |
826 | * aaaaaaaassssssssbbbbbbbb | |
827 | * a - Start address for CRC calculation (little endian) | |
828 | * s - Length of data to calculate over (little endian) | |
829 | * b - Boolean, true=write crc, false=don't write | |
830 | * | |
831 | * 0xff200000 - Info record, data field format: | |
832 | * ssssttttdd..dd | |
833 | * s - Size in words (little endian) | |
834 | * t - Info type (little endian), see #defines and | |
835 | * s3inforec_t for details about types. | |
836 | * d - (s - 1) little endian words giving the contents of | |
837 | * the given info type. | |

d8950599 KR |
839 | * 0xff400000 - Start address record, data field format: |
