I created a file that is identical to the qsys file of the project I downloaded from Intel and only removed the IPcore Triple speed Ethernet I don't use. I don't know if my .qsys is missing anything from that project, but every connection and IPcore I have installed is the same. i use quartus pro 18.0 and my board is Cyclone 10Gx development kit. can you tell me what is the peripherial ID representation value in system.h? I also try checking 'Ignore mismatched system ID & timestamp' but .elf file download failed. I have refreshed the connection but Connected System ID and Connected system timestamp are still not found. Can you support for me to solve this? A project I downloaded from Intel and the system ID properties notification image is attached below: Re: COMBINE ELF FILE INTO SOF FILE Thanks for your support. This problem has solved. But I have new problem when I try to run C file in fpga Nios II. I receive a error message: "Connected system ID hash not found on target at expected base address". I search to solve this problem, and I have added "System IP Peripherial" IPcore, but this problem can't solve. Can you support me to solve this? Thanks. my project has attached below: Error:"Connected system ID hash not found on target at expected base address" Hi, I try to run C file in FPGA Nios II and I receive a following error message: "Connected system ID hash not found on target at expected base address". My .qsys had System ID peripheral IPcore. My project with this qsys is attached under post. Thanks a lot, Viet COMBINE ELF FILE INTO SOF FILE Hello, I have some problems when I try to combine elf file into sof file. 1, I use "sof2flash" but I get a message that: "unrecognized device family in SOF". Does this command "sof2flash" not support for Cyclone 10GX? 2, when I use "elf2flash" and "nios2-elf-objcopy", I generate a hex file from elf file. I try to use Convert Programing File in Quartus Pro and generate a jic file. I loaded that file into the Cyclone 10GX kit with EPCQL1024. But, it doesn't work like when I load and run sof file and elf file. I think it work like when I load sof file. elf file after combine into sof file doesn't work. 3, I try to load pof file into the Cyclone 10GX with EPCQL1024, but I receive the message cannot add target device EPCQL1024 to device chain when in current programming mode. I tried to use active serial programming and JTAG but it doesnt work. Can anyone tell me how to solve this problem? Thank you so much. best regard, Viet
