Introduction
For cross developing of applications we provide virtual machines with preinstalled toolchains. Choose the virtual machine which fits to your DHCOM target (Debian 8 on target -> Debian 8 virtual machine). Debian 8 does include support for architecture armhf and armel (Debian 6 only armel). By default Debian 8 is configured for armhf. The sections Code Examples for Userspace-Applications to Access SPI, I2C, GPIOs, and more and Booting via NFS apply for Debian 6 and Debian 8.
Debian 9 "Stretch" VM image (for VMware and VirtualBox)
Get the virtual machine
- Get VMware player or VirtualBox
- Debian 9 "Stretch" VMware Image
Default password for devel user: devel
Default password for root user: root

- Enter default user devel password (devel)
- Enter default user devel password again (devel)
- Enter your own user devel password
- Enter your own user devel password again

Qt5 Development
Qt5.5.1 prebuilt and preinstalled
We provide the prebuilt Qt5.5.1 libraries including WebEngine (only QtQuick) and WebKit in /work/qt5/sysroot/. This directory contains a Debian 8 based rootfilesystem which is prepared for DHCOM i.MX6, the matching sysroot (*-dev packages), and the Qt5.5.1 libraries installed.
Qt5.7.1
We support the latest Qt5.7.1 on our DHCOM i.MX6 and DHCOM am335x. Please download and install the qmake-sysroot-mx6-crossarmhf_5.7.1-1.0 or qmake-sysroot-am33-crossarmhf_5.7.1-1.0 package to the DebianVM:
- open a terminal
- # for i.MX6: wget https://dl.dropboxusercontent.com/u/19433555/DHCOM/imx6/qmake-sysroot-mx6-crossarmhf_5.7.1-1.0_amd64.deb
- # for AM335x: wget https://dl.dropboxusercontent.com/u/19433555/DHCOM/am335x/qmake-sysroot-am33-crossarmhf_5.7.1-1.0_amd64.deb
- install the package
- # sudo dpkg -i qmake-sysroot-mx6-crossarmhf_5.7.1-1.0_amd64.deb
- now the sysroot and qmake is ready to use
- path to qmake is /work/qt5_mx6_armhf/sysroot/usr/local/qt5.7.1/bin/qmake
Build a Qt5 Application via console
- open a terminal
- navigate to your Qt5 sources
- # /work/qt5/sysroot/usr/local/qt5.5.1/bin/qmake your_own_app.pro
- # make
Qt Creator
- Start Qt Creator IDE
- Open demo project TwoLED: /work/qt5_Demos/TwoLED
- There you can find the configurations for your own project.

Use Virtualbox instead of VMware Player/Workstation
VMware Maschine mit VirtualBox starten (German)
Booting via TFTP/NFS
Prepare the virtual machine
- Setup nfs-kernel-server
- Install thf nfs server:
$ sudo apt-get install nfs-kernel-server - Create a nfsservice directory:
$ mkdir /work/nfsroot - Place the root file system in the folder
$ cd /work/nfsroot; sudo tar xf jessie....tar.gz - Remove network config from rootfs
$ rm /work/nfsroot/etc/systemd/network/wired-dhcp.network - Check whether the line below is part of the /etc/exports file
/work/nfsroot X.X.X.0/255.255.255.0(rw,no_root_squash,no_subtree_check,insecure)- The X must be substituted by our network settings
- Restart the nfs-server with
4 /etc/init.d/nfs-kernel-server restart
- Install thf nfs server:
- Setup tftp-hpa server
- Install a tftp server :
$ sudo apt-get install tftpd-hpa - Create a tftp service directory:
$ mkdir /work/tftp - Edit config:
$ sudo vi /etc/default/tftpd-hpa- Take care that TFTP_DIRECTORY points to your tftp service directory, for example '/work/tftp'
- Copy Kernel and DeviceTree into the tftp service directory
- Restart the tftp-server with
$ /etc/init.d/tftp-hpa restart
- Install a tftp server :
Setup the DHCOM Module for TFTP/NFS Boot
This example works with static IP addresses and is tested with DHCOM i.MX6 U-Boot 2015.10 and Kernle 4.4.38. It is possible to work with DHCP, too. For further information see https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt
- Enter U-Boot console by pressing DEL/BACKSPACE on a RS232 terminal while switching on the power supply of the target
- Set IP addresses
| # env set serverip 192.168.178.90 # env set ipaddr 192.168.178.91 |
- bootargs for nfs root (up to Debian Jessie)
| # env set rootfs 'root=/dev/nfs nfsroot=192.168.178.90:/work/nfsroot/ ip=192.168.178.91:192.168.178.90::255.255.255.0:dhcom:eth0:none' |
- bootargs for nfs root (since Debian Stretch)
| # env set rootfs 'root=/dev/nfs nfsroot=192.168.178.90:/work/nfsroot/,nfsvers=3 ip=192.168.178.91:192.168.178.90::255.255.255.0:dhcom:eth0:none' |
- load Linux kernel and devicetree with tftp (change filename and path to match you setup)
| # tftp ${loadaddr} zImage # tftp ${fdt_addr} dtbs/imx6dl-dhcom3B-pdk2.dtb |
- set bootargs and boot
| # run linuxargs # bootz ${loadaddr} - ${fdt_addr} |
- optional: save it to be permanent
| # env set bootcmd 'tftp ${loadaddr} zImage; tftp ${fdt_addr} dtbs/imx6dl-dhcom3B-pdk2.dtb; run linuxargs; bootz ${loadaddr} - ${fdt_addr} # env save |
