I’ve been trying to bring up socfpga-linux provided by SoC EDS 15.1.1.60 on Altera Arria 10 board with my own hardware design. As the kernel comes up and tries to read SD card to mount root filesystem, it gives error, the log of which is given below. I’ve given the entire U-boot dump including the environment variables. Please help me out as to what the issue is, and what is needed to get over this.
