customizing soc_system.rbf for cyclone V
Hello all,
I am trying to change the soc_system.rbf from the GSRD to a customized one.
The only differences between the FPGA designs are:
1. The SYSID has been modified.
2. The original rbf size is about 2Mb while the customized size 7 Mb.
Running the steps from the GSRD manual: https://www.rocketboards.org/foswiki/Documentation/CycloneVSoCGSRD
The build and customation proccess runs fine without errors, also under $TOP_FOLDER/gsrd_socfpga/cyclone5-gsrd-images/cyclone5_gsrd_ghrd the new, bigger rbf file is located.
However when flashing the gsrd-console-image-cyclone5.wic file to an SD card, it seems like the original rbf is packed instead of the customized!
Also, trying to manually load the bigger rbf file from the FAT partition fails with error -6 and only the original rbf file is successfully loaded to FPGA fabric.
Has anyone encountered this issue?
Hi
The steps you shared is getting the sd card image from the pre built source.
That is why you are seeing the old sysID still present.
Could you please follow the steps below :
Section " C. Prepare SD Card Image"
From the steps above you will pack the newly created rbf into the SD Card.
