Hi, I've put this query to the supplier of the embedded systems that I use: www.embeddedarm.com, interested in whether this is a live topic in the wider community. Given the valid concerns about write tolerance, wondering whether there's any consideration of using USB hard drives (real rotating ones) in place of flash file systems on memory sticks for embedded Linux. I can see reasons ...

I'm using telnet from a command prompt under WinXP to connect to an embedded linux target. Part of the target boot sequence involves initiating an exit from a startup shell, by entering 'exit '. Telnet interprets this as terminating the telnet session, the command window returns to a C: prompt. Is there a way that I can get the session to just pass the exit command through and han

Sorry if this is off-topic. If it is, I'd appreciate a pointer as to where to look. I am looking at hooking up a 7" LCD panel to an embedded Linux computer. Besides the frustration of realizing that no one really makes a standard interface for these panels, (LVDS, digital, 8 bit, etc...) , what I find far worse is the backlight situation. How, exactly, am I supposed to light up the pa...

Hi, I'm working on high speed data transmission protocol aimed to receive data from low resource FPGA connected to the Ethernet PHY. The protocol is supposed to work on embedded Linux PC with high speed CPU and NIC. The protocol will be used only in a private network, and multiple FPGA systems will be connected via an Ethernet switch to single data collecting embedded system. All design...

Hi, I'd like to share with you my last development - a L3 protocol for transmission of data between low resources FPGA and an embedded system. It may allow you to use low cost/low resources FPGAs together with cheap Ethernet switches and simple Linux based embedded systems (or just reflashed Linux based Ethernet routers working as both a switch and an embedded system) to create data...


Accounting for memory use in a running embedded Linux process

I have a Linux process that uses, say 16 MBytes of memory according to "top". When I dump the executable using objdump, I can account for only, say, 7 MBytes of that. It's not doing much if any dynamic allocation ( a quick grep fest showed nothing at all, but I wouldn't trust that as truthful for the moment ). What tools do I need to account for the difference? And why couldn't I Goog...


Embedded linux and achievable timer rate

I've been stopped dead by a limitation with the ARM-9 250 MHz SBCs, running Linux, that I've been relying on for my next project. The maximum rate I can run a repeat timer (setitimer, etc) at is 50Hz, ie. 20000 uS repeat time. If I set the repeat rate any faster the thing still repeats every 20mS. Is this a standard 'feature' of Linux SBCs? Does anyone run an SBC that will do significantl...

Hi, I'm writing some embedded SW that runs on a small embedded Linux system and I need to access some WSDL web services. Can anyone suggest a good (small, clean, easy to use) WSDL client framework that will expedite my delivery of this code ? If it was free too then that would be useful, but my client will probably object to the GPL so it will need to be an embeddable licence where I can sh...

I'd like to pick people's brains about aspects of different *suppliers* of Zynq boards. Avnet and Digilent are front-runners, but any info/opinions about other suppliers would be helpful too. - ease of using their embedded linux.

Hi guys, I have a program which has the possibility of doing a shutdown or reboot remotely by doing a popen("reboot") or popen("halt") call after doing some cleanup. I have found that if I execute the application directly from the command line, this works and the shutdown or reboot takes place immediately. However if I try it when the program has been automatically executed on startup throu...

The local control will be a touch-screen display...

I think this is little OT here, because the question is mostly network oriented. However my nodes will be Linux embedded boxes and some solutions could be very low-level, so I think many of you could help me in some way. I have N Ethernet hosts based on embedded Linux. Each one features an Ethernet interface dedicated to the final user that could change the IP address configuration.
