I'm trying to compile a simple project for cortex-m55, the project right now is pretty simple, just the main and CMSIS DSP and NN.
If I enable float-abi, no matter if hard, soft or softfp, I get the following compilation error:
../src/CMSIS/NN/Source/SoftmaxFunctions/arm_softmax_s8.c: In function 'arm_exp_on_negative_values_mve_32x4':
../src/CMSIS/NN/Source/SoftmaxFunctions/arm_softmax_s8.c:74:1: internal compiler error: in trunc_int_for_mode, at explow.cc:59
Thank you Alex.
I used the latest downloadable release of CMSIS NN, I'll try with the sources in the repo and let you know.
