  1. All: I've been incrementally developing both hardware (MicroBlaze with AXI peripherals) and software for the MicroBlaze itself. I've set up my software program size so that all software and hardware configuration can fit into a single .bit file. I've been able to program the flash several times, but yesterday have been getting errors while attempting to erase the flash. Notes are below. Is there a HW/SW program I could load onto the FPGA to prove or disprove that the flash is broken? Thanks!!
