I am trying to find out the actually used version of CMSIS-NN … As README.md says
By default CMSIS-NN is built by code that is downloaded to the TFLM tree. It also possible to build CMSIS-NN code from an external path by specifying CMSIS_PATH=<…/path>. As a third option CMSIS-NN can be provided manually as an external library.
I’d like to know which version (commit) I have to use to build the appropriate CMSIS-NN lib.
