Why can't I access the Intel® MAX®10 Altera Dual Boot IP in my Qsys system? - Why can't I access the Intel® MAX®10 Altera Dual Boot IP in my Qsys system? Description Due to a problem in the Quartus® II software versions 14.0 and 14.1, the Altera Dual Boot IP address map is incorrectly set to 0x0 - 0x7. This will cause issues accessing the IP using Nios® II or any Avalon Master. Resolution To work around this problem in the Quartus II software versions 14.0 and 14.1, follow the steps below: 1. Open the hw.tcl file in a text editor. The hw.tcl for the IP, which is located at <installation directory>\<Quartus version>\ip\altera\altera_dual_boot\altera_dual_boot\altera_dual_boot_hw.tcl 2. Change set_interface_property avalon addressUnits {SYMBOLS} to set_interface_property avalon addressUnits {WORDS} 3. Re-launch Qsys 4. Remove and re-add the component to your system, and re-generate the system This problem was fixed in Intel® Quartus® software version 15.0 Custom Fields values: ['novalue'] Troubleshooting 1506811832 False ['novalue'] ['FPGA Dev Tools Quartus II Software'] 15.0 14.0 ['MAX® 10 10 FPGAs'] ['novalue'] ['novalue'] ['novalue']
