Other Parts Discussed in Thread: SYSBIOS
Hello, there.
I use PSDK RTOS and PSDK QNX. And I added my TIOVX custom kernels to ${PSDK_RTOS_PATH}/vision_apps/kernels using PyTIOVX as follows:
from tiovx import *
code = KernelExportCode("my_custom_kernel", "r5f", "CUSTOM_APPLICATION_PATH")
code.setCoreDirectory("r5f")
kernel = Kernel("my_custom_kernel")
kernel.setParameter(Type.USER_DATA_OBJECT, Direction.INPUT, ParamState.REQUIRED, "configuration", ['my_custom_kernel_input_t'])
kernel.setParameter(Type.USER_DATA_OBJECT, Direction.OUTPUT, ParamState.REQUIRED, "recognition_result", ['my_custom_kernel_output_t'])
kernel.setTarget(Target.IPU2)
code.export(kernel)
And I confirmed that the module was loaded and the Create(), Process(), Delete() callbacks were executed normally.
After OSPI flashing in SD boot mode, the sample app was executed in OSPI boot mode.
And I tried to bind the socket server as in the following code, but it failed.
(Build success, but run-time failure)

Please answer about my question. :)
