TDA4VM: How to use UDMA in CCS Window with C7x for memcpy

Part Number: TDA4VM

Hello TI,

I'm using API UDMA Driver from PDK 07_03_00_29 with Window based CCS.

I maked an application to initialize UDMA parameters and UDMA functions and there is no error when I compile.

The program is hanging on run when I runned on C7x so I have to stop it manually and I got a message :

No source available for "Sciclient_threadStatusReg() at C:/Users\Jacinto\workspace_v10\test8_udma.out(3) 0xa821648c(4)"

Then I checked the issue and I noticed the function UdmaInitPrms_init() may be the problem but I'm not sure.

Is it that PDK UDMA or other drivers are not supported on CCS window based ?

If not can you help me resolve this issue.

Regards,

Pascal

Hi Pascal,

Please try out building udma_memcpy_testapp for C7x using the make command:
make udma_memcpy_testapp CORE=c7x_1 BOARD=j721e_evm

For more details refer PDK User Guide:

Hi Don,

Thank you for your answer !

I runned "pdksetupenv.bat" as it said on the User Guide. And as you told me on another post (TDA4VM: C7x UDMA exemples - Processors forum - Processors - TI E2E support forums) I tried to run "gmake udma_memcpy_testapp BOARD=j721e_evm CORE=c7x_1 BUILD_PROFILE=<release>" but I got an error :

gmake: *** No rule to make target 'udma_memcpy_testapp' . Stop.

Can you help me resolve this issue ?

Regards,

Pascal

Hi Pascal,

Looks like there is some issue with running "pdksetupenv.bat"

Can you please try building from "PDK_INSTALL_DIR/packages/ti/build" as mentioned in https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/07_03_00_07/exports/docs/pdk_jacinto_07_03_00_29/docs/userguide/jacinto/getting_started.html#build-steps

Use the command:
For release build:-
gmake udma_memcpy_testapp BOARD=j721e_evm CORE=c7x_1 BUILD_PROFILE=release

For debug build:-
gmake udma_memcpy_testapp BOARD=j721e_evm CORE=c7x_1 BUILD_PROFILE=debug

Regards

Don

Hi Don,

Sorry for the late reply.

I runned pdksetupenv.bat from "PDK_INSTALL_DIR/packages" then I built all the applications and libraries for C7 core with the command :

C:\ti\ti-processor-sdk-rtos-j721e-evm-07_03_00_07\pdk_jacinto_07_03_00_29\packages\ti\build>gmake -s all BOARD=j721e_evm CORE=c7x_1

And I got an error : 

error: unable to rename

gmake: *** [makefile:141: all_apps] Error 2


So I tried with your command : 

C:\ti\ti-processor-sdk-rtos-j721e-evm-07_03_00_07\pdk_jacinto_07_03_00_29\packages\ti\build>gmake udma_memecpy_testapp BOARD=j721e_evm CORE=c7x_1 BUILD_PROFILE=release

And I got an error either it's release or debug : 

gmake: *** No rule to make target 'udma_memecpy_testapp'.  Stop.

Hello,

I managed to build all PDK applications and libraries.
But when I load the binary files like udma_memcpy_testapp or dmautils_baremetal_autoinc_1d2d3d_testapp to C71X_0 by using CCS, It still gets stuck at No source available for Sciclient_serviceSecureProxy().

Can someone helps me resolve this issue ?

Pascal
