A section is identified by a number. +Within a section, three commands are supported: "load", "jump" and "call": + +section(0x626f6f74) // hex for 'boot' +{ + load hw_init; + call hw_init; + load rockbox; + jump rockbox; +} + +Finally, both elftosb and sbtoelf tools use key files. A key file is a list of keys. +Each key consist is 128-bit long and is written in hexadecimal: + +00000000000000000000000000000000 + +The parser does not handle blank line and only allows a final newline at the end of the file. +A file is allowed to contain zero (0) keys. |
