srec_mips_flash - Man Page

The file must start with '!R' to reset the state machine. White space appears to be ignored, except as it serves to separate tokens.

Data is presented as 32-bit hexadecimal numbers, in the normal big-endian text number format.  To write them to memory, you have to know if the target is big-endian or little-endian. for little endian targets, reverse the order of the bytes in this number.

The eight bytes following a '>' are a sort of comment.  The SDE code reads like they are displayed in the flash programmer as a kind of progress indicator.

The number following '@' is a new address for the following data.

Each segment must be erased before it can be written, this is done with the '!E' command.  Each segment is assumed to be 128kB in size.

Special segments must unlocked (with the '!C' command) and locked again (with the '!S' command).

This file format contains no checksum mechanism.

This format is specified using one of the -Mips-Flash-Big_Endian or -Mips-Flash-Little_Endian options.  The endian-ness must be specified on the command line, because there is nothing in the file contents to indicate the endian-ness of the data it contains.

In general, binary data will expand in sized by approximately 2.3 times when represented with this format (worse if you use shorter lines).
