It contains all system-required shell commands and drivers ready for ROM-5420 platform. We do not offer IDE developing environment in ROM-5420 BSP, users can evaluate and develop under Ubuntu 10.
3.2 Package Content We would offer you two different kinds of Linux package for ROM-5420. One is prebuilt system image for system recovery another is source code package (BSP). 3.2.1 Source Code Package ROM-5420 source code package (BSP) contains cross compiler, Linux source code, Uboot source code, root file system and some scripts used in OS development. Some of above components are developed by Advantech and the others are developed by open source community.
3.2.1.3 image This folder includes uImage & u-boot. 3.2.1.4 image/rootfs Linux adopts Hierarchical File System (HFS), image/rootfs is the Linux file system in highest level of the tree structure. – bin → Common programs, shared by the system, the system administrator and the users. – dev → Contains references to all the CPU peripheral hardware, which are represented as files with special properties.
– mksd-linux.sh → A script to setup up a bootable SD card if users build their images 3.2.1.6 source This folder contains sub-directories “linux-3.0.35” and “u-boot-2009.08”. They are the source codes of the Linux kernel and U-boot. Linux is a clone of the operating system UNIX.
All instructions in this guide are based on Ubuntu 10.04 LTS developing environment. Please install the Ubuntu 10.04 LTS at your PC/NB in advance. Advantech offer you a script to setup the developing environment quickly. You can refer following steps to setup your developing environment: 1. Open "Terminal" on Ubuntu 10.04 LTS. 2. $sudo su (Change to “root” authority) 3. Input user password 4. Change directory to BSP's scripts folder 5. #. setenv.sh (To configure the developing environment automatically) 6.
Note! You have to wrap “setenv.sh” once you open a new "Terminal" utility every time. (i.e. #source setenv.sh) Note! It is suggested to change to “root” authority to use the source code. 3.4 Build Instructions This section will guide you how to build the u-boot & Linux kernel. 3.4.1 Build u-boot Image Advantech has written a script to build the u-boot quickly. You can build u-boot image by follow below steps: 1. Open "Terminal" on Ubuntu 10.04 LTS 2. $sudo su (Change to “root” authority) 3.
This section will guide you how to use the Linux source code. You will see some examples of using BSP source code in this section. 3.5.1 Add a Driver to Kernel by menuconfig Figure 3.1 Linux Kernel Configuration 27 ROM-5420 User Manual Software Functionality You can add a driver to kernel by menuconfig. Here is an example to guide you how to add a RTC driver (Seiko Instruments S-35390A) to Linux kernel. Please refer to the following steps: 1. Open "Terminal" on Ubuntu 10.04 LTS. 2.
8. Select “Device Drivers”→”Real Time Clock”, you will see an option “Seiko Instruments S-35390A” on the list. Choose this option then exit and save your configuration. Figure 3.2 Selecting Seiko Instruments S-35390A 9. Change directory to “source/linux-3.0.35/arch/arm/mach-mx6”, edit the “boardmx6q_ROM-5420.h” and “board-mx6q_advantech.c”. Please add below codes to source/linux-3.0.35/arch/arm/mach-mx6/boardmx6q_ROM-5420.
By default, ROM-5420 shows a boot logo when booting up. You can replace the logo to whatever your want by following below steps: 1. You have to download “netpbm” corresponding to your OS version from internet first, 2. Install “netpbm” by typing $sudo apt-get install netpbm. 3. Prepare your boot logo. For example: bootlogo.png (Under folder Desktop/bootlogo) This picture should be in PNG format and less than 224 colors. It is suggested to have the image resolution equal to your LCD panel size. 4. 5. 6. 7.
2. Insert this Linux system SD card to ROM-DB7500 and connect serial console. 3. On ROM-5420 platform, type #root (Login) 4. On ROM-5420 platform, type #cd /mk_inand 5. On ROM-5420 platform, type #./mkinand-linux.sh /dev/mmcblk0 6. On ROM-5420 platform, type “y “(Start to copy files, wait until it shows [Done]) 7. Power off and remove this SD card. Then you can boot from onboard flash without SD card. 3.6.
#. setenv.sh (To configure the developing environment automatically) #cd ../source #mkdir helloworld (Create your own work directory on the Desktop) #cd helloworld (Enter the work directory) #gedit helloworld.c (Create a new C source file) Edit the helloworld.c with the following source code: 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. Save the file and exit. #$CC -o helloworld helloworld.c (To compile helloworld.c) Then you can see “helloworld” in current directory.

-v be more verbose for some error conditions interface The name of the interface. This is usually a driver name followed by a unit number, for example eth0 for the first Ethernet interface. If your kernel supports alias interfaces, you can specify them with eth0:0 for the first alias of eth0. You can use them to assign a second address. To delete an alias interface use ifconfig eth0:0 down. Note: for every scope (i.e.

Chapter 5 5 Advantech Services This chapter introduces Advantech design in serviceability, technical support and warranty policy for ROM-5420 evaluation kit.
5.1 RISC Design-in Services Advantech RISC Design-in Services help customers to reduce the time and work involved with designing new carrier boards. We handle the complexities of technical research and greatly minimize the development risk associated with carrier boards. Easy Development Advantech has support firmware, root file-system, BSP or other develop tools for customers. It helps customers to easy develop their carrier board and differentiate their embedded products and applications.
With the spread of industrial computing, a whole range of new applications have been developed, resulting in a fundamental change in the IPC industry. In the past System Integrators (SI) were used to completing projects without outside assistance but now such working models have moved on. Due to diverse market demands and intense competition, cooperation for (both upstream and downstream) vertical integration has become a much more effective way to create competitive advantages.
In view of this, Advantech proposed the concept of Streamlined Design-in Support Services for RISC-based Computer On Modules (COM). With a dedicated professional design-in services team, Advantech actively participates in carrier board design and problem solving. Our services not only enable customers to effectively distribute their resources but also reduce R&D manpower cost and hardware investment.
