## Generate Initial RAM Disk
genromfs -f initrd -d ../apps/bin -V "NuttXBootVol"

## Show the size
riscv-none-elf-size nuttx

## Export the Binary Image to `nuttx.bin`

  nuttx.bin

## Prepare a Padding with 64 KB of zeroes
head -c 65536 /dev/zero >/tmp/nuttx.pad

## Append Padding and Initial RAM Disk to NuttX Kernel
cat nuttx.bin /tmp/nuttx.pad initrd \
  >Image

## Copy the config
cp .config nuttx.config

## Dump the disassembly to nuttx.S
