Question

在FPGA ZC706上启动linux-3.14.4时出现以下错误。我已经按照以下方式构建了所有工具：

火箭芯片：

$ Latest master branch is checked out and generate boot.bin

riscv-gnu-toolchain:
$ ./build.sh (riscv64-unknown-elf)
$ make linux (for riscv64-unknown-linux-gnu-gcc)

Linux kernel:
$curl -L https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.14.41.tar.xz | tar -xJkf -
$ cd linux-3.14.41
$ git init
$ git remote add origin https://github.com/riscv/riscv-linux.git
$ git fetch
$ git checkout -f -t origin/master
$ make ARCH=riscv defconfig
$ make -j12 ARCH=riscv vmlinux

根光盘映像：

$ dd if=/dev/zero of=root.bin bs=1M count=64
$ mkfs.ext2 -F root.bin

引导：

1. First copy all files (vmlinux, root.bin, boot.bin, devicetree.dtb, uImage,  uramdisk.image.gz) into sdcard.
(2) $ mkdir /sdcard
$ mount /dev/mmcblk0p1 /sdcard
$ ./fesvr-zynq +disk=/sdcard/riscv/root.bin bbl /sdcard/riscv/vmlinux

启动开始，但卡在某一点上。以下是引导错误

任何人都可以帮助我，不管我错过了什么。我也尝试过 Linux的33年3月14日;同样的错误来了

Answer 1

I can now boot kernel on SPIKE ISA as well as FPGA. I omit some steps while building root.bin mentioned at https://github.com/riscv/riscv-tools.

$ dd if=/dev/zero of=root.bin bs=1M count=64
$ mkfs.ext2 -F root.bin

will generate empty root.bin. We need to mount disc image and complete the file systems after completing busy box building as mentioned at https://github.com/riscv/riscv-tools
