    Hi Tamil Sorry for delayed response, ideally there shouldnt be any problem with basic debugging, start using kernel debugger to step through,
    Follow some of the basics from below

    https://wiki.ubuntu.com/Kernel/KernelDebuggingTricks

    https://wiki.ubuntu.com/Kernel/KernelDebuggingTricks

    Ping me if you have any specific question on these.
    Again apologies for delayed response was travelling

    Hi Rajeev,
    I like to know, when I read or write some thing to file ,how it actually stores to hard drive. My question is eg: when i use fwrite in c program to store my name in the text file,how fwrite links to system call, drivers and finally how it writes to hard disk.I know its very generic question . if possible give me the roadmap for me to proceed. After 3 day I am again starting with kernel module programming :)

    Hi Rajeeev,
    when I started doing small kernel module programming , I feel like, I don't have much knowledge about Linux system files , So I am gonna to start from the base by following the book "Essential Linux Device Drivers", Mean while I will keep you update about my learning status . Thanks for your continues support

    Hi Rajeev,
    i wanna to have serial communication between my Linux system and between my piccolo c2000 real time controller . how to do i start proceed.

  19. Rajeev TiwariFebruary 26, 2013 at 8:15 AM

    i m not sure if i understood your question, But there are plenty of ways you can have serial communication from controller to linux box.
    follow some standard rules
    1. Make sure you use correct cables (2 & 3 crossed out, no handshake lines to start with)
    2. Seperate the devices, i.e. connect your Linux machine to a PC running a terminal program and try to establish 2-way communication -
    3. connect Linux and C2000 only if they both work against a known and proven device i.e.
    RS232, IEEE 1394

    Hi Rajeev,

    1)how pci bus id are allocated to new devices connected to it.

  26. tamil vananMarch 12, 2013 at 11:56 PM

    2) How pci bus connector connects to Processor,For example if my system has 3 PCIe connector's , in which PCIe network card is connected in one pcie slot and PCIe graphics card on other and one left empty.how this two will simultaneous communicates ????.

  27. Rajeev TiwariMarch 13, 2013 at 8:08 AM

    Just do ctrl+f and search for "writing-an-alsa-driver" you will find a section called
    Basic Flow for PCI Drivers: go into the full code example and you are there. Let me know if you still have issue locating it.

    You can use either of these for the same.
    Eclipse
    etbeans

  34. UnknownMay 24, 2013 at 1:24 AM

    Hi Rajeev,

    I have knowledge about Low Level Drivers. I have worked on some high level drivers also.
    But I don't have deep understanding about high level drivers.

    1). My question is how my driver is attached to bus driver..?
    2). When a device is connected,How the bus(I2C) driver find out which driver is there for this device.
    3). How the kernel takes care of driver table.
    4). What about probe in a driver.
    5). Who calls probe.
    6). In the kernel where can i find specific code that shows the calling of probe function of the specific driver.
    7).

    Hello Sathyavathi,

    I think you should do some study, also i dont know what you are trying to do so it would be difficult to help without knowing what you want. But please read some of the documents attached.

    I am sure these will help.

    Hello Akash,
    What help you are looking for, did you get a chance to go through the basic of Device Drivers? In my opinion start going through Device driver section in the blog and go through example program to start with. there are some good articles about Porting as well. go through it... Send me email if you have any doubts.

    Hope this helps

    Hi Rajeev,

    I have a question regarding PCIe hot-plug.
    Can we do a hot-remove of a device when it is mounted?
    i.e i mount the device and hotremove it without unmounting.
    If yes. the filesystem will handle unmount of the device or we have handle unmounting the device in the driver.
    Second scenario- Can i go in the directory where the device is mounted and hotremove the device?
    i.e mount /mnt
    cd /mnt then hot remove the device.
    here also the filesystem will take care of unmounting and flushing the cache?
    or it should be handled in driver. if unmounted from mount point what is the behaviour?
