Honored Contributor1) Yes, I can program my custom HW using JTAG
2) Now, this is where it gets interesting, the restore.sh programs 2 factory restore files, previously created, restore_0 and restore_1. The two are different, one is HW the other is SW and a collection of other bits an pieces. You can't just program them anywhere you wish interchangeably. restore_0 has to go at base 0x0800_0000 (offset=0x20000) and restore_1 has to go at 0x0A00_0000. This is because restore_0 has the NIOS II which needs to boot SW from a specific location. I can individually program restore_0 and restore_1 to the expected bases (0x0800_0000 and 0x0A00_0000) correctly but if I try to program the USER HW at any base (0x0800_0000 or 0x0A00_0000) with any offset, it does not configure the FPGA. Could it be that I am missing something in creating the user.sof ? I figured that if I can download it with JTAG and it works then it is good to use for programming into FLASH, no? Thanks, S.
