Honored ContributorYes, why shouldn' it possible that both Nios boot out of the same flash?
The reset address of the first one is flash+0 and the second one gets flash+0x100000. Here is the text of the flash programmer for the first nios system: # ! /bin/sh# # This file was automatically generated by the Nios II IDE Flash Programmer.# # It will be overwritten when the flash programmer options change.# cd D:/temp/EvalBoard_Cyclone/MP3_Player/software/MP3_Player_eth_ide/Debug # Creating .flash file for the FPGA configuration $SOPC_KIT_NIOS2/bin/sof2flash --flash=U5 --offset=0x600000 --input=D:/temp/ EvalBoard_Cyclone/MP3_Player/MP3_Player.sof --output=MP3_Player. flash Info: ******************************************************************* Info: Running Quartus II Convert_programming_file Info: Command: quartus_cpf --no_banner --convert D:/temp/Ev alBoard_Cyclone/MP3_Player/MP3_Player.sof MP3_Player.rbf Info: Quartus II Convert_programming_file was successful. 0 errors, 0 warnings Info: Processing ended: Thu Jan 27 09:41:31 2005 Info: Elapsed time: 00:00:01 # Programming flash with the FPGA configuration $SOPC_KIT_NIOS2/bin/nios2-flash-programmer --input=MP3_Player.flash --sof=$SOPC_ KIT_NIOS2/components/altera_nios_dev_board_cyclone_1c20/system/altera_nios_dev_b oard_cyclone_1c20.sof --cable='USB-Blaster [USB-0]' --base=0x00800000 27.01.2005 09:41:35 - (INFO) nios2-flash-programmer: Launching Quartus Programme r to download: D:/Altera/niosii_v11_build137d/components/altera_nios_dev_board_cyclone_1c2 0/system/altera_nios_dev_board_cyclone_1c20.sof Pre-Reading 434KBytes of data from U5: |----.----+----.----| ********************* (4.176 sec).

If you want I can send you a very small Quartus project (SOPC-builder design with 2 PIOs and 1 user interface) that shows the error message.
