J784S4XEVM: Problem to use MMALIB Test

Mickaël GUIBERT

Part Number: J784S4XEVM

I am unable to execute the tests of MatrixMultiply_ixX_ixX_oxX.

I set up the following variables

$CGT7X_ROOT /opt/ti_compilers/ti-cgt-c7000_4.1.0.LTS
$CMAKE_CURRENT_LIST_DIR ./test_mmalib/ti-processor-sdk-rtos-j784s4-evm-11_01_01_01/mmalib_11_01_00_06
$CMAKE_SOURCE_DIR ./test_mmalib/ti-processor-sdk-rtos-j784s4-evm-11_01_01_01/mmalib_11_01_00_06
$KERNEL_NAME linalg_c7xmma/MMALIB_LINALG_matrixMatrixMultiply_ixX_ixX_oxX

My target is a J784S4EVM. First, I want to us test the 202 data file.

rm -rf build; cmake -S ./ -B ./build -DTARGET_PLATFORM= -DSOC=RESERVED -DDEVICE=C7120 -DBUILD_MODE=use_prebuilt_and_test -DMMALIB_DEBUGPRINT='1' -DKERNEL_NAME_TO_TEST=$KERNEL_NAME -DTEST_CASE=ALL -DBUILD_TYPE=debug ; cmake --build ./build

When a launch on my CCS env... in the console. Capture d’écran 2025-12-08 161105.jpg

Some can help me ?

My problem is that I can't see the outputs, and moreover, the internal registers of the MMA aren't changing. That seems strange to me.

Hello,

Sorry for the trouble. From the CCS console output, I can see that no tests are actually being run, so makes sense that MMA internal registers aren't changing.

In the build command, I see

-DSOC=RESERVED

Given that you are on a J784S4 EVM, that value should be -DSOC=J7AHP. Apologies for the confusion on device naming; we need to update MMALIB build SOC names.

On -DTEST_CASE=ALL, I'm not sure if ALL works, but if you replace this with the number 202, it should build for that test case only.

Best,

Will

Thank you for your reply.
I succeeded to compile and run test 202 and even others! This gave me a basis for comparison for my other problem, which I explained in request E2E1596371 (J784S4XEVM: Problem with MMA configuration for Mul operation with operands on 32 bits and output on 8 Bits (A and B))
