Note: pls refer to https://developer.nvidia.com/embedded/downloads for the latest update on the image.
The latest version of jetpack is 28.5 for now, feel free to update the link I attached as default.

Command (m for help):
From here you can see the rootfs start from block 24576 with block size 512bytes. So We need to mount the image from offset 24576 * 512 = 12582912
root@C:~# mount -o loop,offset=12582912 jetson-nano-sd-r32.1-2019-03-18.img /mnt root@C:~# ls /mnt/
bin boot dev etc home lib lost+found media mnt mxnet opt proc README.txt root run sbin snap srv sys tmp usr var
root@C:~#
I recommand to cp all the files from image to the local folder. because all the changes under /mnt will change the origin image, and also there is a size limitation from Image. Here its max size is 12GB. Maybe not enough for the later use.
root@C:~# cp /mnt/* /home/alan/rootfs-nano -rapvf root@C:~# apt install qemu-user-static root@C:~# cp /usr/bin/qemu-arm-static usr/bin/ root@C:~# cp /usr/bin/qemu-aarch64-static usr/bin/ root@C:~#
Here is a mount shell script (ch-mount.sh) to help chroot to the target file system. Here we use qemu to setup a simulation to install and get some packages conveniently. Of course you can copy from a real device.
#!/bin/bash
function mnt() {
echo "MOUNTING"
sudo mount -t proc /proc ${2}proc
sudo mount -t sysfs /sys ${2}sys
sudo mount -o bind /dev ${2}dev
sudo mount -o bind /run ${2}run
#sudo mount -vt tmpfs shm ${2}dev/shm
#sudo mount -t /dev/shm ${2}dev/shm
sudo chroot ${2}
}
function umnt() {
echo "UNMOUNTING"
sudo umount ${2}proc
sudo umount ${2}sys
#sudo umount ${2}dev/shm
sudo umount ${2}dev
sudo umount ${2}run
sudo umount ${2}host
}
if [ "$1" == "-m" ] && [ -n "$2" ] ;
then
mnt $1 $2
elif [ "$1" == "-u" ] && [ -n "$2" ];
then
umnt $1 $2
else
echo ""
echo "Either 1'st, 2'nd or both parameters were missing"
echo ""
echo "1'st parameter can be one of these: -m(mount) OR -u(umount)"
echo "2'nd parameter is the full path of rootfs directory(with trailing '/')"
echo ""
echo "For example: ch-mount -m /media/sdcard/"
echo ""
echo 1st parameter : ${1}
echo 2nd parameter : ${2}
fi
root@C:~# cp /etc/resolv.conf etc/
root@C:~# bash ch-mount.sh -m rootfs-nano
Now you entered a simulation system and experience just like you are on target board. It's usefull to get some packages and dependency libs without a dev kit board on hand.

From now on, there are two possible ways to compiling the mxnet. You can chose step 4 or step 5.
root@C:/# mv mxnet ./
root@C:/#cd mxnet
root@C:/#cp make/config.mk .
From jetson-nano-sd-r32.1-2019-03-18.zip official release Opencv 3.3.1 CUDA 10.0, Cudnn and TensorRT and pre-installed. If you want to use mxnet with CPP version, try to compile with USE_CPP_PACKAGE=1
root@C:/#make -j $(nproc) USE_OPENCV=1 USE_BLAS=openblas USE_CUDA=1 USE_CUDA_PATH=/usr/local/cuda USE_CUDNN=1
lan@C:~/src/mxnet$ make -j $(nproc) USE_OPENCV=1 USE_BLAS=openblas USE_CUDA=1 USE_CUDA_PATH=/usr/local/cuda USE_CUDNN=1
alan@C:~/src/mxnet$ cd python && python setup.py bdist_wheel && python3 setup.py bdist_wheel
alan@C:~/src/mxnet/python$ ls dist/

alan@C:~/src/mxnet$ scp ../lib/libmxnet.so dist/* jetbot@(ip):~/
It will cost u several hours depend on your CPU version. For the speed direct build > cross-compile > compile under simulation.
Download the cross compile toolchain from Jetpack.
We just need the gcc-4.8.5-aarch64.tgz for mxnet. if you want to cross compile the kernel gcc-4.8.5-armhf.tgz is also required.
alan@C:~/toolchain$ tar xpvf gcc-4.8.5-aarch64.tgz
alan@C:~/toolchain$ mv install gcc-4.8.5-aarch64
alan@C:~/toolchain$

You can see there are two key folders sysroot and bin. From sysroot, you can get the basic libs used by the gcc/g++. From bin, you can get the compile tools: gcc, g++,ar,ld...
On the target:
root@C:/# rm /usr/include/aarch64-linux-gnu/cblas.h
root@C:/# cp /usr/include/aarch64-linux-gnu/cblas-openblas.h /usr/ include/aarch64-linux-gnu/cblas.h
