| Sound Open Firmware Tools |
| ========================= |
| |
| This is a collection of open source tools used to develop open source audio |
| DSP firmwares for ALSA. |
| |
| Building and Installing |
| ======================= |
| |
| ./autogen.sh (only needed first time) |
| ./configure |
| make |
| make install |
| |
| |
| rimage |
| ====== |
| |
| rimage is used to convert ELF executable firmware files to the firmware file |
| formats used by the kernel drivers. |
| |
| e.g. |
| |
| rimage -i elf_file -o kernel_file -m machine |
| |
| rimage can also convert kernel firmware formats to flat binaries formats to |
| assist in debugging :- |
| |
| e.g. convert to flat binary, then ELF then dissasemble |
| |
| rimage -i /lib/firmware/intel/reef-byt.ri -o image.bin -b -m byt |
| |
| xtensa-byt-elf-objcopy -I binary -O elf32-xtensa-le -B xtensa image.bin image.bin.elf |
| |
| xtensa-byt-elf-objdump -D image.bin.elf > image.dis.txt |
