    Lorin Netsch
    Does the Linux-C6x_2.0_Beta2_Release support getrusage with RUSAGE_THREAD? I noticed that in the Codesourcery toolchain RUSAGE_THREAD is not defined in libc/usr/include/bits/resource.h, but it is included in libc/usr/include/linux/resource.h. Can you tell me what the difference is between the two...

    Rex, You were correct. These two environment variables were not set and that would solve the problem. However, I did not see any reason to download CCS and the Codesourcery tools again. I examined the file linux-c6x-2.0-beta2/linux-c6x-project/setenv and at the end of the script it had commented...

  • Forum Post: c6678 - writing blob.bin to flash

    Lorin Netsch
    I have built a blob.bin file according to the Linux-c6x-2.0-beta2 Release Notes, but the instructions are not clear on how to load this to the nand flash. Do I move this to the program_evm/binaries/evm6678l directory, renaming it as nand.bin and then follow the instructions in the User Guide?

  • Forum Post: Re: c6678 - Kernel panic

    Rex Chang
    I assume the program you are running is in user space. The error means the data corrupted in the middle of operation and Kernel does not have a way out of it. Do you think GDB will help to debug it? Please refer to the GDB wiki page in Linux-c6x Ecosystem Features.

    I get the same results as you for the above commands, but I don't see what that has to do with how the shell is acting. An example of what I am mentioning is: / # ls /bin/* ls: /bin/*: No such file or directory but ls works if I don't specify path expansion characters: / # ls ...

    In the serial I/O console for the EVM, the shell does not appear to have pathname expansion enabled. Is it possible to turn it on?

    The code that I wrote started multiple threads. The GNU tools seem to use a single threaded model, so as a work-around I changed my code so it does not use threads. That seems to have fixed the problem. -Lorin

    Hi, Jerry, There are 2 directories under syslink/samples, hlos and rtos. Codes under hlos directory are meant to run in the user space of the linux, and rtos is to run under BIOS. When running in linux user space, it is not using .xe66 image. Hence I am a bit confused. The example is for linux envrionment...

    Hi, Christophe, The kernel configuration can be done by running "make menuconfig" in linux-c6x directory, and select "Processor type and features" submenu. Be sure the environment variables are set by sourcing the setenv in linux-c6x-project before menuconfig. It seems that the...

    Hi, Christophe, When you run "make menuconfig" from a subprject directory, linux-c6x, the environment has not been set up yet. You should source the setenv file in linux-c6x-project. Then run "make ti_evmc6678_defconfig" to set c6678 default configuration, and menuconfig to alter...
