How can I regenerate correct Image?

[nohahanon]

Hi there!

I wanna execute C program on this board so I need to regenerate Image but this one I made in local cannot work. If you success to boot linux with Image you build in your machine, please teach me your environment or used tools!

Thanks.

• Files used for booting:
  • sipeed_tang_nano_20k.fs: Created with "./make.py --board=sipeed_tang_nano_20k --build"
  • sipeed_tang_nano_20k.dtb/dts: Created with "./make.py --board=sipeed_tang_nano_20k --build"
  • Image, rootfs.cpio, fw_jump.bin: For the procedure, I followed https://github.com/litex-hub/linux-on-litex-vexriscv#-generating-the-linux-binaries-optional, and I used the ones obtained from https://buildroot.org/ to create each file.
  • boot.json: I referred to the boot.json from Prebuilt Bitstreams and Linux/OpenSBI images. litex-hub/linux-on-litex-vexriscv#164, and I modified the parts that originally mentioned rv32.dtb and opensbi.bin.

{
    "Image": "0x40000000",
    "sipeed_tang_nano_20k.dtb": "0x40ef0000",
    "rootfs.cpio": "0x41000000",
    "fw_jump.bin": "0x40f00000"
}
