We need opinions of embedded or real-time software designers on language features for shared resource protection. We are improving our toolset for development of embedded and real-time (and other similar) software. Our toolset includes a graphical programming tool and a configurable real-time kernel. We are now introducing a shared resource protection mechanism to our kernel. We need to ad...

I have found that I can avoid the long JFFS2 scan in U-Boot if I write my kernel image (uImage) to a specific address in flash and using this address in my boot command rather than putting uImage in the filesystem and having to scan for it. My problem is updating the kernel remotely. Now I can simply scp a new uImage file to my boot directory in the filesystem. Is it possible to remotely co...

Hi Guys, I am working on some RTOS, in which I see lot of interrupts "enabling" and "disabling" code in most of the RTOS API's to protect kernel data. For example, Semaphore API's, Message Queue APIs, Runtime memory management API's. Is enabling / disabling interrupts only to protect the kernel data? Why I am asking this is whenever interrupts are disabled, I am scared of losing timer int...

Hi, I am poring from Linux 2.4 to Linux 2.6. My board is based on PPC 8270 processor of FreeScale (former Motorola). The uImage (compressed Linux kernel) size on Linux version 2.4 was ~ 720 Kbytes. What size should I expect on Linux 2.6 ? What is the typical/minimal uImage Linux kernel size , assuming that I am using TCP/IP, UART, etc. The drivers that we added are not so b...

I am running Linux 2.6.26 on a PPC. I want to boot linux without using a bootloader to speed up the boot process but, due to the size of the kernel, I cannot put it at the reset vector. I was told that I have to put a branch instruction at the reset vector location and branch to the location where my kernel is. How do I put a branch instruction at the reset vector?

Hi , I am loading the kernel 2.6.12 for MIPS target using vxworks boot loader. VxWorks kernel 5.5.1 image is at 0x80010000 and I have linked the linux ELF image with the same start address in Makefile. And the start_kernel with 0x80ae600 address. As it is vxworks version is after 5.4 , it can identify ELF compatible images. VxWorks boot loader is able to identify start_kernel but then i...

Hi. Is somebody there using this scheduler or has tried it? I couldn't find much information o it other than MontaVista's promotional material which does not help much. After a quick glance it seems rather straightforward and not much intrusive and besides it's architecture independent. Though the latest version available in sourceforge is for kernel 2.4.16 I have been able to apply i...

Hi, I have the "MicroC/OS-II The Real Time Kernel" book (2nd ed), but since I bought it used, it came without the companion CD. Does anyone have the companion CD, or know where to get it? I looked on Micrium's website, and while they have many downloadable files, this one is not one of them. TIA My con-ned email address can be corrected by removing - and changing one other cha...

Hello all Im trying to get linux up and running on my system. I have 16MB of SDRAM at 0x20000000 and 2MB of dataflash. I've started with the at91rm9200dk files in the kernel as my start point, and I can get it to boot if and only if I disable my dCache. Im imaging there is a setting somewhere Im over looking that is still trying to map the caches with 32MB of ram (which the dk has) but I ha...

Hi there Sorry for this NewBe question, I?m try o get started in using Atmel AT91RM9200 Board. I've read a lots of how-to and so on. Now running a 2.6 Kernel on it :) I'd like to use a USB video board on it so i think i have to cross compile this driver. My problem i doesn?t find any example through the internet which told me how to do this. Maybe someone could give me some tips. ...

HI, Any of you have used XilKernel in application for PowerPC 405. I am required to develop a system based on embedded PowerPC 405 on Xilinx Virtex4 FPGA. Since i have 4 processes running on the uP so i want to schedule them in round robin fashion. Just wondering if any one can tell me how hard it is to do. I cannot use any other OS since this kernel is free and as document said very compa...

Hi, Could any one please advice some effective debugging tools for RTEMS? I want to watch kernel signals generated between parent and child processes, share memory data interchange between multi-threads. If there is no tools like that, is there any guideline for developing these tools? Thank you very much for your attention. Sam.
