The example projects for the FPGA embedded Cortex-M1 do not work at all with Xilinx Vivado 2020.1. The instructions that work fine with the 2019 version do not update the ITCM when using the 2020 version. I have several designs using the M1, and would like to be able to upgrade my Xilinx tools. I also have some suggestions about how to organize the M1 distribution for greater utility, if anyone has any interest in the opinion of an experienced user.
Apparently this is not of interest to anyone.
