Suggestion: debug Linux in general
Hi,
I am trying to boot Linux on my development board and it stucks
somewhere, — I do not see log in prompt on my Hyper Terminal. I am new
to embedded Linux stuff, and not sure how to debug this.In standalone mode, I usually start GDB to trace the software and
see on which code is the problem, but how should I do for Linux? I was
told briefly that Linux turns on MMU in the very early stage which makes
it very difficault to debug kernel. How true is it?I wonder if there are very good book/tutorial about Linux debug in
this booting phase? I checked out “Building Embedded Linux”, it mentions
some linux debug using GDB, but not in details and seems only for
application.Any suggestion is higjly appreciated.
Thanks.

I mean without the Linux on the Grashopper. Can I build standalone applications and load them somehow into the board without using a JTAG programmer. Maybe U-Boot can also load binary images? Is there a sample project somewhere which shows the way it goes? You may ask why I want to do so? For me such OSes like Linux (Windows also) made it all much complicated, especially to a non-Linux programmer like me. The AP7000 chip features much nice hardware. If I want to use it I have to build kernel drivers for ...Hi, I would like to try embedded Linux on my 5282 Eval board. I am lost as for the tools and compiler that I need to achieve this task. Presently I am using CodeWarrior development suite. I downloaded the Linux BSP for 5282 (m5282evb-3.0-2004116.iso). The document mentions Platform Creation Suite (PCS)? 1) Where can I download embedded Linux for my 5282 board? 2) What compiler do I need to be able to run embedded Linux on my 5282 Eval board? ...Hi, Does anyone know of any means to debug Linux Kernel (ARM) by making use of CCS? (Code Composer Studio). I was wondering if there is some kind of CCS plugin to support ELF images. johnHi, I have few clarification regarding Linux. Why do many peoples prefer Linux as platform for designing embedded. Which Linux OS should we begin with it. Is it similar to windows kind of(like programming IDE, debugging, Burning the code etc).Hi, I would like to take advantages of the hardware TWI (I2C) functionality, which is available on the AT91SAM9G20. Therefore, I would like to write a Linux kernel module for it. However, when reading the documentation in the Linux kernel source tree regarding TWI (Linux kernel 2.6.30.9), I see some "worrying" comments. To start with, in the file /linux-2.6.30.9/drivers/i2c/busses/Kconfig, I read the following: Quote:Hi, I am having sam9261 and want to debug u-boot.

I havent linux yet so could u please suggest me some books(e-books) and topics to be covered to become embedded linux geek. Is learning kernal programming and device drivers development enough or do i need to learn something more. I am also ready to by a hardcopy of a book if it covers all the required topics.

Rick Lehrbaum, Editor-in-chief, LinuxDevices.comI am working with MCB2300 kit in Linux-Ubuntu. I have installed Keil version in Linux-Ubuntu through Wine. For debugging I am using ULINK2 via JTAG. After compiling the code when I try to debug I get an error dialog which displays No ULINK device found. I am able to work with the same ULINK2 in Windows. But now my requirement is on Linux-Ubuntu. So please let me know whether I can use the ULINK2 in linux or not.Hi all, I am going to make a set top box with a linux box. So, i am looking for some TV Capture card that support Linux. Also would be easy to develop some software for the Card. Any suggestion? Or, did my approach is corret on using a tv capture card on linux to implement my set top box? would the market use the other solution. As i am new and doing it for my school project Thanks in advance ChunHello Friends, I am working as Embedded System Designer with 4 years of experience in C programming(C51, PIC, ARM, AVR) up to 32 bit. Now i want to learn embedded Linux programming. my query is ==gt from where, I am starting with Embedded Linux? ==gt which starter Kit is useful for better experience on Linux? ==gt Friendly ARM board is better or not for beginner? Thanks amp Regards, Ghanshyam Rajsthan - IndiaI'm an experienced embedded software developer but I've never used Linux or GCC. Which Linux distribution would you recommend for a beginner? I expect to be able to dual boot with Windows. I was planning to buy the Red Hat Linux 9 Bible but Red Hat has moved on to newer versions. Is there something else that would be better? Thanks Kevin -- [Remove ".invalid"s to respond by email.]Hello! I have a board based on AT91SAM9263-EK with a little but annoying difference: SDRAM is smaller. Because of this difference I can't use prebuilt images. So I've build some on my own. I've built AT91Bootstrap which directly loads the linux kernel. I am using AT91Bootstrap-1.15. Linux-2.6.33.4 and the root-filesystem is built using buildroot. When watching the serial port I get the following output (please do not feel disturbed by the debug messages): Code:Hey all.. I am interested in getting into embedded Linux! I bought a few text books on Linux and embedded systems... But, I don't know where to start in terms of an evaluation board and compiler, iv'e Googleed it and there is just so much info! Any one have a good idea for me? Preferably I would want something that has many i/o lines and is below $200 USD, with a decent (free) compiler, USB and Ethernet.
