List commands

The cfsai utility provides commands to inspect supported SoCs, backends, and backend extensions. These are useful for discovering the exact strings to use with build and profiling commands.

List-targets command

The cfsai list-targets command prints a list of supported SoC, core, and accelerator combinations. Use this to check the exact strings to pass with the --target option when building a model.

cfsai list-targets

Sample output

ADSP-21834.FX
ADSP-21834W.FX
ADSP-21835.FX
ADSP-21835W.FX
ADSP-21836.FX
ADSP-21836W.FX
ADSP-21837.FX
ADSP-21837W.FX
ADSP-SC834.FX
ADSP-SC834W.FX
ADSP-SC835.FX
ADSP-SC835W.FX
MAX32657.CM33
MAX32690.CM4
MAX78002.CM4
MAX78002.CM4.CNN

List-backends command

The cfsai list-backends command prints the supported backends available in your environment.

cfsai list-backends

Sample output

izer
tflm

List-extensions command

The cfsai list-extensions command prints the available extensions for a given backend. You must provide the backend name as an argument. Run cfsai list-backends first to see available options.

cfsai list-extensions <backend>

Sample output izer backend

Clean-cache command

The cfsai clean-cache command clears cached files that CFSAI has downloaded from remote URLs.

CFSAI automatically caches remote files (such as model files provided by a URL) so they can be reused consistently and when offline. If the remote file is accessible, the cache will refresh automatically after one hour to keep model files up to date.

Use cfsai clean-cache to:

  • Save local disk space by removing cached files.
  • Force CFSAI to re-download a remote model instead of using the cached copy.
