Python scripts for AIS and COFF

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
