Hi Ross, The coreinfo.tab file serves only to tell borph there the registers are located, so changing it would only give borph the wrong mapping. These registers are hard-coded in the HDL in the sys_block<https://github.com/ska-sa/mlib_devel/blob/master/xps_base/XPS_ROACH2_base/pcores/sys_block_v1_00_a/hdl/verilog/sys_block.v>. Why do you need to change these addresses?
To change them you would need to modify the HDL and the coreinfo.tab (if you wanted access to them, by name, from borph) and then ensure that the BASE_ADDR and HIGH_ADDR parameters are set correctly. Be aware that this might cause multiple devices to be mapped to the same space and go BOOM! Probably only when you try to access that address ;) Wes Wesley New South African SKA Project +2721 506 7365 www.ska.ac.za On Tue, Oct 22, 2013 at 3:04 AM, Ross Williamson < [email protected]> wrote: > Hi Wes and all, > > So the MMAP is working really quite well on a ROACH-1 - This question > is more my lack of understanding of the tool-chain. > > Does anybody know how to fix the memory address for the various CASPER > brams and registers.
