  • Kernel Panic on Buildroot B2021.10.1

    Hello,


    yes, I have used the exact same board.

    The output is:


    NAND Flash settings

    --------------------------

    uBlockCount = 2048

    uPageCount = 64

    uPageCountBits = 6

    uPageSize = 2048

    uPageSizeBits = 11

    uSpareSize = 224

    uColCycle = 2

    uRowCycle = 3

    uSize = 256

    normal ECC is 40 bits per 1024 bytes

    boot ECC is 40 bits per 1024 bytes

    flashlayout 0: size = 2224, metasize = 36, level = 40

    flashlayout 1: size = 2190, metasize = 2, level = 40

  • Kernel Panic on Buildroot B2021.10.1

    Hello,


    it is just for development purposes. We are trying to switch in the future to linux.

    The previous release of Buildroot worked without problems. Is there a configuration that can be changed when building the linux kernel that would make this release also work ?

  • Kernel Panic on Buildroot B2021.10.1

    Hi,


    I tried to run on PicoMODA9 the new Buildroot release B2021.10.1 but I get a Kernel panic and I don't know why.

    The previous release of Buildroot B2020.04 runs without problems.

    Can you, please, tell me what is I'm doing wrong ?

  • Make a beep

    hi,


    thanks for the quick answer.


    yes it is a picomod1. the speaker is connected to the dio interface.
    can you please give an example on how to make a beep on that speaker.


    thank you very much.

  • Make a beep

    on my PicoMOD1 i see that there is a speaker.
    My question is how can i make a beep sound on that speaker (preferably in Visual C#) ?


    Thank you for your answers !


    PS. sorry for my bad English
