Hi, I have ARM Platform evaluation board (ARM integrator/CP & ARM 920T Processor) in my office. I am a newbie in this area, so just wondering if I can utilise the above platform to be operated under embedded linux OS. (ucLinux or others). How to upload the embedded linux OS to the above platform ? FYI, the platform is connected to my PC using multi ICE interface. I use this interfa...

Hi, I've managed to buy a few Orange PI PC boards for very nice price, to be used as controllers for simple measurement and control system. I have created the Linux image using the newest Buildroot 2016.11 The board booted correctly, but I have found a very strange thing. Even though U-Boot supported Ethernet (also DHCP and TFTP), the Linux kernel didn't see the Ethernet interface. I've...

Hello I am little confused about the memory managent in Embedded Linux. My understanding is that, one of the properties of embedded OS it predictability. And the demand-paging/swapping is something that brings in un-predictability. But in practical situations how is demand-paging handled in embedded linux ? Is it disabled? Are all the pages needed by a process loaded earlier itself?? ...

Hello, I just went through compiling eCos for Falcom x35-xxl-si on SuSE Linux 10, and I thought to share the experience in the hopes to save some time for someone else. SuSE Linux 10 has gcc 4.x as the native compiler, which apparently was a major source of trouble in compiling the toolchain. I used the eCos online documentation as the primary reference for building the toolchain:...

Hi, Im an undergrad working on installing Linux on a custom development board based on the AT91RM9200 (for my senior project). Since this is the first time im doing this, i decided to go for the "linux-2.4.27-vrs1-ATMEL" kernle available from the Atmel site. Incedentally, this kernel is built for the AT91RM9200-EK. But i was befuddled when it came to "make menuconfig"..what are the opti...

I would like to know what is the most popular Embedded GUI Design Software for Linux thesedays. I need a GUI for an embedded linux device, which has a LCD with about a quarter of VGA size. Of course an attractive interface is preferred, as long as it doesn't take huge resource and development efforts (we are not game developers anyway). Our GUI developer have years of experience of designing GUIs ...

I used a simple driver for serial port in Linux with success in many projects, but recently I found an issue with it. The scenario is an embedded Linux (running on iMX6) that runs a QT application (that creates a GUI on a touch display) and a C application that communicates over a serial port. When QT application starts some complex graphics (I see its CPU load reaching 70-80%), the ...

Hi! For an embedded project we want to use the Mity SoC Module with 4MB RAM and ALI M6117D CPU from http://www.icop.com.tw. Our application allows us to choose between linux or dos. We need network, serial port and a few I/Os. What do we have to consider? Does anyone know dos license pricing? Has anyone worked successfully with that kind of CPU-board either with dos or linux? Are there...

Hi, I have some confusion over the degree of SW/HW interaction in USB Host controllers. I have an FPGA design which runs Windriver Linux. I would like to add to the PCB a USB 2.0 host controller chip whose sole purpose in life is to perform everything required to get from the PHY to EHCI. I would then like to map the EHCI registers to the Linux kernel; so that I should not have to write...

I am considering developing on the Yocto project for an embedded Linux project (an industrial application) and I have a few questions for those with experience with embedded Linux in general -- Yocto experience a bonus. Just need to get an idea of what is being commonly done in firmware updates. I have a few requirements, that being authentication, a secure communications protocol, some type o...

Hi, I have a written a Linux driver to control a parallel port (bit bangs data serially) and I want to port it to windows. The Linux device driver is pretty simple, just a few ioctls and that's it. I have no experience with windows driver development. Any help on any of the following, to get me started, would be appreciated: (1) I would like to find a simple skeleton driver that implemen...

Hello, has anyone ever got this combination work on a native Linux box? Their Windows (cygwin) stuff on the other hand works very nicely. I prepared an old Linux RedHat 9.0 (2.4.20 kernel) distribution (on the very same machine where the Windows version of ocdremote works perfectly), so that their proprietary driver "ravenpp" would compile. The kernel modul loads, but after I run: oc...

I don't strictly need a full Linux OS, but I have to use a third-party SDK released only for this OS (it is a commercial TTS engine solution). What is the minimal hw platform that runs a full Linux (not uClinux)? Is there a single-chip (integrated Flash and RAM) solution? I don't think. What is the simplest and lowes cost solution for a medium volume production (1000pcs)? I don't need...

Dear All I am a rookie to Linux. I have two units of two-way Linux router Boxes {Platform: iDirect iDS Platform (XScale)} BOX "A" is ok. No problems. While BOX "B" had some errors so I had a thought to format the flash I init the BOX B by using the command "fis init" I noticed that these below entries are missing (Linux and RootFS) on BOX B Redboot> Fis list Name FLA

Hello, All. As we all know that the standard linux kernel does not allow us to access physical address of devices, so the physical address must be converted to virtual address before any IO operation. In my disign, the cs8900a is configured for IO mode, its bus physical address is 0x1001_0000, and its default IO base address is 0x300, ARM9(Cirrus Logic EP9302) processor, linux kernel 2.4.21. ...

Hello there! I am new to low level programing. I have a Moxa 5232 Device server. I have a rs485 device that I like to be able to access from a Linux computer. It is a 2 wire 1/2 duplex rs485 enabled device. After installing the Moxa drivers I have a "/dev/ttyr00 & /devttyr01" devices/ports on my Linux server. In order for me to access this device, I wrote a C program. It basically ope...
