I'm using the Altera Cyclone V Soc dev Kit and Linux Angstrom provides by rocketboards (http://rocketboards.org/foswiki/documentation/gsrd141) Kernel is : 3.10 LTSI. For me, Linux can't start if any serial cable is not plugged on UART USB port (J8).I already removed getty which launched a login prompt at start up. I also tried to change CMD_LINE in .config kernel's file to disable console. What should I change to enable linux to start properly ? Is that simply possible ? Have I to rebuild the kernel or u-boot and change configuration ?
could you make a complete reset? flash a 14.1 SOF file, flash 14.1 SD card GHRD image, and ensure all teh jumper in the default form? just to isolate is not the version of the GHRD that you are using got error.
