The extended manifest is a place to store build-time known firmware metadata such as the firmware version or a used compiler description. Given that information is read on the host side before firmware startup, this is especially important for ABI compatibility checks. This part of the output binary is located as a first structure in the binary file and it is skipped in the DSP loading routine; so, the attached information does not affect DSP memory.
Add a new element¶
To add a new element to the extended manifest, do the following:
Add a new element definition in the
ext_manifest.hfile located in the firmware and driver repository.
Add a new element declaration in the
ext_manifest.cfile located in the firmware repository.
Add a new element handling routine in the driver repository:
