acturally, this week I tried severy times to call algorithm_dmaSwMs link in HLOS side but failed. and the log printed in screen is: ALG: ERROR: No alg create function specified (algId = 0, max:28) !!! after browsing the source code, I found that the function AlgorithmLink_DmaSwMs_initPlugin() hasn't been called. and the caller is AlgorithmLink_initAlgPlugins() function which located in " links_fw/src/hlos/links_a15/algorithm/algorithmLink_cfg.c ".
and I try to call the AlgorithmLink_DmaSwMs_initPlugin() in AlgorithmLink_initAlgPlugins() but failed again, the compiler told me that :
" algorithmLink_cfg.c:(.text+0x36): undefined reference to `AlgorithmLink_DmaSwMs_initPlugin' "
and after checking the source code, the header file included is
You are getting undefined reference that means you have not defined AlgorithmLink_SurroundView3d_initPlugin function in correct file.
"
it seems that when algorithm link used in hlos side, the coder should put source into vision_sdk\apps\src\hlos\adas\src\alg_plugins path.
my question is: if I create a new algorithm link and use it in hlos side, I will put this link in above file path, but, if an exsisting algorithm link of rtos is called, should I put its source code to above file path too? it seems that we need more files to add into the source code.
could you provide some advice on this situation? thanks a log.
There used to be a common header file (we think some system_cfg.h), which included defines macros for all algorithms. Can you please search for ALG_dmaSwMs and see if it is defined somewhere? If this is not defined, then DMA SW Ms will not be included in the build.
I've tried to re-edit the system_cfg.h file, but it seems that this file is auto genergated by shell script, i.e. it would like turn back to original file after I edited and saved it. and I found a little difficult to find the shell script which generated this system_cfg.h file. could you kindly point out the shell script file or something else to auto edit the system_cfg.h file? thanks in advance.
actually I've solve this issue by making a new dma mosaic link and putting it in ... links_fw/src/rtos/links_common path , now it works and produces the mosaiced images already. this link take reference on algorithm_dmaSwMS link develped by your colleagues.
and currently I wanna use the algorithm_dmaSwMS link in my project, since I guess it would run more fluently on the board.

Actually this file is auto-generated depending on the algorithms selected for the usecase configuration.. What is the MAKECONFIG and MAKEAPPNAME you are using? Depending on the ALG_LIST, it generates this config header file. Can you please check if ALG_dmaSwMs is included in the ALG_LIST?
currently this issue is solved, now ALG_dmaSwMs could run at ipu and dsp1 core now, and mosaic several images to one image. Thanks for your kindly help and support and that make me feel I'm not fighting alone. below is some tips for using rtos algorithm links in hlos side: 1，$(APPNAME)/configs/$(MAKECONFIG)/cfg.mk set BUILD_ALGORITHMS=yes 2, $(APPNAME)/src/rtos/alg_plugins/Makefile add : include $($(MAKEAPPNAME)_PATH)/src/rtos/alg_plugins/dmaSwMs/SRC_FILES.MK 3, build/Makefile add: $(MAKE) -fMAKEFILE.MK -C$($(MAKEAPPNAME)_PATH)/src/rtos/alg_plugins $(TARGET)
then system_cfg.h would include "#define ALG_dmaSwMs"
