Tool/software:

    Hi, 

    please check your path again. I see an possible issue with double backspace just before "bin" folder.

    Otherwise please provide a full log so we can see what happened. We don't know what "mind connect base code" is.

    Thanks for your response. Since we are moving from TISDK 8.1 to TISDK 9.1, and since I don't have a toolchain directory in TISDK 9.1, this path isn't accessible in my code at the moment. I believe I may need to modify that path now, as I had it in the previous version of TISDK 8.1 and am using the same mindconnect library code now. nonetheless, can you kindly assist me in determining which path, for the GCC compiler, I should provide in this new TISDK 9.1?

    Since there is no toolchain directory in TISDK 9.1, how can I search the above path in TISDK 9.1 for the GCC compiler that I am receiving the above error for? Could you please help me figure out which path I should provide now, in place of that one?

    Hi Neha,

    did you follow the TI Yocto build guide?

    https://software-dl.ti.com/processor-sdk-linux-rt/esd/AM335X/09_01_00_001/exports/docs/linux/Overview_Building_the_SDK.html

    According to the E2E entry you quoted that will install the tools required. So if you can build the TI default file system I assume you can customize that for your needs by adding a custom recipe. Do you work with Manu Kumar?

    Regards, Frank

    yes i work with manu kumar we are in same team. i have built the default TISDK 9.1 in my system.

    so all the required tools should be on your machine. Can you try a search for a compiler binary for example? Unfortunately I have no such setup.

    i installed tisdk 9.1 and build the u-boot and kernel both successfully.

    this is the build folder where i am trying to path for c compiler for replacing toolchain path -

    from these directory which is relevant that i am checking and tried one path xxx.bb file

    and i am getting this error 

    modifying the .bb file is enough or cmake.txt also need a change ? or this path it self not correct ? if you aware please guide me here

    Hi Neha,

    I assume you are deviating from the Yocto build process. If you setup your own process it is difficult to help. But I suggest you check where the mach=armv5t comes from. You are using an ARMv7 compiler and that might not support that old architecture (ARM9 cores or so...). I also suggest you look at the SDK build logs. They should show all the correct compiler paths and options to compile for AM335x and it's Cortex-A8 core.

    Regards, Frank

    You can refer to the file "$SDK_installation/Rules.make", which lists the toolchain to build u-boot/kernel... in AM335x Linux SDK 9.1
    "$SDK_installation/external-toolchain-dir"
    Best,
    -Hong

    thanks frank and hong for your response.

    i realized i did not installed external toolchain in my system. when i followed those steps and i can see the toolchain path -

    and i followed this steps - 1.1.6. GCC ToolChain — Processor SDK Linux for AM335X Documentation

    and i have done necessary changes in .bb and cmake.txt files and its build successfully now without errors.

    Thanks.
