I design a p2020 board. Using CW while run on sram everything is ok. But if run on DDR3, always initialize fail, ccs prompt :error writing registers, ccs last error ELF is not in expect HALT mode. could this be a hardware problem? I connect ddr's RESET pin to GPIO1, and in the init_core.tcl, I added script and made GPIO1 high before enable mem interface, is that OK?
