Cannot intall Linux onto Altera DE2-115

[nhannx-viosoft]

I followed the tutorial from example program/12_linux, which install linux on Terasic DE10-Lite board with Altera MAX10 chip. I used Terasic DE2-115 board, Cyclone IV family chip.

• I already built MIPS soft-core and program to FPGA
• I already build kernel and rootfs to generate vmlinux image, however there is no defconfig and dts file for DE2-115 board, cyclone IV chip, so I reuse files for MAX10 chip as tutorial.
  I can load vmlinux image to MIPSfpga, however cannot boot linux. After typing "continue" from gdb console, nothing happen. There is none log from gdb console and minicom console.
  I'm not sure reusing defconfig and dts files for MAX10 board is suitable for DE2-115 board.
  Any suggestion is welcome! Thank you
