part6_cnn build is failing with the following error:

ERROR: [XFORM 203-504] Stop unrolling loop 'ReuseLoop' (firmware/nnet_utils/nnet_dense_resource.h:43) in function 'nnet::dense_wrapper<ap_fixed<16, 6, (ap_q_mode)5, (ap_o_mode)3, 0>, ap_fixed<16, 6, (ap_q_mode)5, (ap_o_mode)3, 0>, config15>' because it may cause large runtime and excessive memory usage due to increase in code size. Please avoid unrolling the loop or form sub-functions for code in the loop body.

Device Specs:

Is it my machine running out of ram or could it be a bug in vivado?
