Hi guys I am starting this new thread in hope that it will be a good sharing platform for both advanced users and the beginners. Actually what I am going to discuss here is that how to run linux kernel on the STM32F407VGT6 controllers the main feature of which is that it is MMU less. Many people might say that it's easy to run linux on the MMU less devices as the linux kernel has its o...

I need to develop an embedded application running on Linux, to be more specific, Wind River Linux 4.0 is my favorite for now. My application requires a timer, or scheduler, which is required to tick my application for about every 1ms. I say "about" because there is no strict timing requirements, and either 1.01ms or 0.98ms would be acceptable. In my application, written in C++, I will impleme...

Does anyone have any experience, or know of any vendors, of small microcontroller development tools than run natively on Linux? I'm looking at processors in the 8051/AVR/Z8 etc class. I'm not looking for embedded Linux--I'm looking for a C compiler/IDE package that allows me to develop for that processor on my Linux workstation. I need the processor in my design for simple switch-scanning LED-ligh...

Hello all. While porting firmware from Linux 2.4 to VxWorks 6.x, I came across a Linux object named "wait_queue". I'm trying to figure out what's the best VxWorks object that fulfill the Linux "wait_queue" task. I started to use VxWorks message queues for it, but I'm not sure that it is the same synchronization concept. Does anybody have any experience on this? Regards, Ebastec

I'm playing with a Raspberry system, however I think my question is about Linux embedded in general. We all know that the OS (linux or windows or whatever) *should* be gracefully powered down with a shutdown procedure (shutdown command in Linux). We must avoid cutting the power abruptly. If this is possible for desktop systems, IMHO it's impossible to achieve in embedded systems. Th...

After porting our application from Linux 2.4.26 to Linux 2.6.10, I am seeing it taking 35 seconds to write to a file when using NFS.

When I run out of flash with Linux 2.6.10, there is no dela...

I was idly looking to see what was out there in the low end Linux space - something bigger than an ESP32 but more production friendly than a Raspberry Pi. I came across this excellent guide: https://jaycarlson.net/embedded-linux/ He builds dev boards for 10 different chips from 7 vendors, just to see how it all goes - both hardware and software. The results are quite interesting. An...

In particular, what editors or IDEs are you using...

Hi I have always feels that , the open source software more unstable. Especially when I use Linux, there are always many problems, and most of them are hard to solve. Such as eclipse for linux, I have tried it on some linux, like ubuntu, suse, I felt that , it's more unstable than windows edition. Do you have the same feeling? why is this could happen?
