[Cyclone V SoC] Trouble implementing FPGA-to-HPS Bridges Design Example (Intel Design Example)


Hello all,


First of all, I am a novice when it comes to soc development. I was trying to implement Intel's FPGA-to-HPS Bridges Design Example ( on my DE1-SoC board.


I edited the quartus files to reflect the SDRAM timings of this board, ran tcl scripts and updated the main verilog file to reflect the pin assignments, and then I compiled correctly and uploaded to the board.


Then, following the design example instructions, I imported the project into eclipse, built successfully, and then ran the program in DS-5 Debugger mode. The program ran but stalled at a wait point in the debug file. Here is a snip of what appears in the command window:


Connected to running target Altera - Cyclone V SoC (Dual Core) cd "C:\[...]\CV_FPGA_to_HPS_Bridge_Design_Example\software\Altera-SoCFPGA-HardwareLib-FPGA2HPS-Bridge-CV-GNU" Working directory "C:\[...]\CV_FPGA_to_HPS_Bridge_Design_Example\software\Altera-SoCFPGA-HardwareLib-FPGA2HPS-Bridge-CV-GNU" source /v "C:\Program Files\DS-5 v5.29.3\sw\debugger\configdb\Scripts\"   No SYSID registers could be found.

Why does the program just stop here? It is as if it does not find the breakpoint? Pressing the continue button does not do anything in Eclipse. I do not know how to address this problem, and I didn't change a lot from the design example, so I feel like it should work well unless I'm running it incorrectly.


Any help at all would be greatly appreciated! If I can get this example to work it would be so useful to me

Please try any other  example like hello world or FFT as given in the link below, so that we can be sure that 

any edits like SDRAM settings edit or script changes are not causing this issue.

Thanks and Regards
