Part Number: TDA3XEVM

Tool/software:

What part of Chains_main_vision.c do I need to modify to use it on IPU1_1?

I added ipu1_1 as below, but the build is not working.

SRCDIR += $($(MAKEAPPNAME)_PATH)/src/rtos/common

SRCS_$(IPU_PRIMARY_CORE) += \
		chains_main_bios_settings.c \
		chains_main_bios.c \

ifeq ($(A15_TARGET_OS), Bios)
ifneq ($(RADAR_ONLY),yes)
SRCS_$(IPU_PRIMARY_CORE) += \
		chains_main_bios_settings_vision.c \
		chains_main_bios_stereo.c \
		chains_main_bios_avb.c \
		chains_main_bios_multi_cam.c \
		chains_main_bios_single_cam.c \
		chains_main_bios_iss.c \
		chains_main_bios_opencl.c \
		chains_main_bios_misc.c \
		chains_main_bios_rsvp.c \
		chains_main_bios_tidl.c \
		chains_main_bios_cam_radar_combo.c 

ifeq ($(IPU_SECONDARY_CORE), ipu1_1)
SRCS_$(IPU_SECONDARY_CORE) += \
		chains_main_bios_vision.c 
endif

ifeq ($(OPENVX_INCLUDE),yes)
SRCS_$(IPU_PRIMARY_CORE) += chains_main_bios_openvx.c
endif

endif
endif

ifeq ($(A15_TARGET_OS), Linux)
ifeq ($(ROBUST_RVC_INCLUDE),yes)
SRCS_$(IPU_PRIMARY_CORE) += \
		chains_main_robust_rvc.c
else
SRCS_$(IPU_PRIMARY_CORE) += \
		chains_main_linux.c
ifeq ($(EARLY_USECASE_ENABLE), yes)
SRCS_$(IPU_PRIMARY_CORE) += \
		chains_early_usecase.c
endif

INCLUDE_INTERNAL_INTERFACES += radar
INCLUDE_EXTERNAL_INTERFACES += radarLink \
                               radarFirmware
endif
endif

ifeq ($(A15_TARGET_OS), Qnx)
SRCS_$(IPU_PRIMARY_CORE) += \
		chains_main_linux.c

endif

How do I use i2c on ipu1_1 core?

I did i2cinit in main_common_ipu1_1.c, but it doesn't work and an error occurs.

Void IPU1_1_main(UArg arg0, UArg arg1)
{
    UInt32 state;
    UInt32 coreId = System_getSelfProcId();

    Bsp_deviceI2cInit(); 
    
    while (1)
    {
        BspOsal_sleep(100U);
        Utils_getAppInitState(coreId, &state);
        if (state == CORE_APP_INITSTATUS_DO_EXIT)
        {
            break;
        }
    }
}

Hi,

I think we do use I2C on IPU1_0 for configuring sensor and external devices, so can you please refer/use existing code in the vision apps for initialing external device using I2C?

I checked the operation by referring to the example.

I want to pass a specific variable from IPU1_1 to IPU1_0.

How can I do it?

Regards,

Kim

Hi Kim,

I am sorry, but is this related to I2C failure that you are seeing on IPU1_1?

There can be multiple ways you can use share variables between IPU1_0 and IPU1_1. You can use IPC or you can keep this variable in some non-cached shared memory etc..

Hi,

No, it has nothing to do with the error.

The existing issue was resolved by directly controlling the register, not the init function.

Since the issue has been resolved, I will create a new ticket for the previous issue.

Regards,

Kim
