Does the EDMA3 LLD support ARM core in Linux?

Hello everyone

I am trying to use EDMA3 on ARM core, the ARM core is running in Linux. BTW, I am using K2HEVM. I found an example in the EDMA3 LLD installation folder (~/ti/edma3_lld_02_11_13_17/examples/edma3_user_space_driver). When I was trying to compile the example from the folder evmTCI6626K2H, multiple compiling errors were popped out, such as undefined references to sem_init in the main.c.

In the makefile, it mentions several libraries, showing below. However, I cannot locate those libraries. The entire makefile is in the attachment.

# Libraries and Include paths
EXT_LIB_a15host = $(edma3_lld_drv_PATH)/lib/a15/$(PROFILE_$(CORE))/edma3_lld_drv.aa15fg $(edma3_lld_rm_PATH)/lib/tci6636k2h-evm/a15/$(PROFILE_$(CORE))/edma3_lld_rm.aa15fg -lrt -lpthread
EXT_INCLUDES = -I$(edma3_lld_drv_PATH) -I$(edma3_lld_rm_PATH) -I$(edma3_lld_PATH)/packages

My question is: does this example suit for ARM core running in Linux? If the answer is yes, where can I find those libraries?

Thanks

    Dear Xining Yu,
    edma3_lld_drv_PATH=C:\ti\edma3_lld_2_12_01_23\packages\ti\sdo\edma3\drv
    Here, you can get the EDMA3 A15 (ARM) libraries in EDMA3 LLD location.

    Hi Titus

    Does this EDMA3_LLD support ARM in Linux? According to this website(http://processors.wiki.ti.com/index.php/Processor_SDK_RTOS_EDMA3), it looks like that the EDMA3 LLD is for SDK RTOS.

    When I use the makefile method to build the example project, I encountered too many missing *.mk files, so I tried to compile the project in Eclipse. My project is in the attachment.

    When I tried to cross-compile the example project in eclipse, it pops out an error "cannot find -l/home/arrc-3190/ti-processor-sdk-linux-k2hk-evm-02.00.02.11/linux-devkit/sysroots/cortexa15hf-vfp-neon-linux-gnueabi/usr/share/ti/ti-edma3lld-tree/packages/ti/sdo/edma3/drv/lib/a15/debug/edma3_lld_drv.aa15fg". I am sure of that the edma3_lld_drv.aa15fg is right there. Why Eclipse cannot open it? (I include the library by configuring the Paths and Symbols as showing below)

    Thanks.

    I think, this project can be build by makefile and not with CCS.
    You need .ccsproject files if you would like to import the project.

    Hi Titus S.

    Thanks for your replying.

    When I use the make file to build the project, it utilize the env.mk file in the folder "/home/arrc-3190/ti-processor-sdk-linux-k2hk-evm-02.00.02.11/linux-devkit/sysroots/cortexa15hf-vfp-neon-linux-gnueabi/usr/share/ti/ti-edma3lld-tree/makerules".

    In this file, it has two environment variable, <CODEGEN_PATH_A15> and <CODEGEN_PATH_A15_GCC>. In the original env.mk, it used the following definition.

    # Cortex-A15
CODEGEN_PATH_A15 = /home/gtbldadm/processor-sdk-linux-fido-build/build-CORTEX_1/arago-tmp-external-linaro-toolchain/sysroots/x86_64-linux/usr/share/ti/gcc-arm-none-eabi
# Cortex-A15_GCC
CODEGEN_PATH_A15_GCC = /home/gtbldadm/processor-sdk-linux-fido-build/build-CORTEX_1/arago-tmp-external-linaro-toolchain/sysroots/x86_64-linux/usr/share/ti/gcc-arm-none-eabi

    However, I cannot locate those two folder in my Linux system. Can you help me to find it?

    THanks.
