Python scripts for AIS and COFF
From Texas Instruments Embedded Processors Wiki
Commandline tools written in python for reading COFF files, generating and dumping AIS images.
These allow the generation of AIS image to be integrated into a commandline or makefile build.
NOTE: These scripts come with no guarantee, though they have been used to create a bootloader and application image that do work on a C6747 DSP. Bug reports gratefully accepted.
The script sources can be viewed/downloaded/cloned at this github gist

aisgen
Generate AIS image from .out file.
Currently supports TMS320C6747/45/43 Bootloader ROM d800k002
https://gist.github.com/1073231#file_aisgen.py
Usage: aisgen.py [options] input.coff [output.ais]
Options:
-h, --help show this help message and exit
-c, --enable-crc enable per-section CRCs
-r ROM, --rom=ROM rom version, eg d800k002
-s, --sequential-read
use SPI sequential read
-v, --verbose verbose log output
-b EMIFB_CONFIG, --emifb-config=EMIFB_CONFIG
E.g. --emifb-config="sdcfg=0x10620, sdtim1=0x01912a08,
sdtim2=0x70080005, sdrfc=0x8000079e"
-p PLL_CONFIG, --pll-config=PLL_CONFIG
E.g. --pll-config="pllm=29, postdiv=1, plldiv3=3,
plldiv5=2, plldiv7=5, clkmode=1, pll_lock_cnt=402,
spi_prescale=6"
-m PINMUX_CONFIG, --pinmux-config=PINMUX_CONFIG
PINMUX_CONFIG=regnum,value[,optional mask]. May be
used more than once E.g. --pinmux-config=0,0x10011101
-m1,0x1001,0xFFFF
aisread
Read AIS file, showing the commands used. Useful for comparing TI aisgen output to the aisgen.py output. Also can generate C header file with AIS content.
Usage: aisread.py [options]
Options:
-h, --help show this help message and exit
-g, --generate-header
generate full header file on stdout
ticoff
Read a TI COFF file into a python object. Currently supports section data and entry point, sufficient for generating loadable image, but doesn't support whole symbol table, or partially linked files.
Usage: ticoff.py [options]
Options:
-h, --help show this help message and exit -d, --dump_data dump section data
