MCU-PLUS-SDK-AM263PX: MCU-PLUS-SDK-AM263PX

Hello Rapeti,

Can you download the latest version of the SDK (10.01.00.34) from the link below and confirm the issue still exists?

disabled the shared memory with the R5FSS1_0  core and R5FSS1_1 core

What steps were taken here?

If you provide an index of 0 does the error go away?

(unitptr_t)(&gIpcSharedMem[0]);

Thanks and Regards,

I have downloaded the latest version of the SDK (10.01.00.34), the issue still exists.

Disabled the shared memory with the R5FSS1_0  core and R5FSS1_1 core means:

I am using IPC for R5FSS0_0 and R5FSS0_1 so in Sys Config i have disabled the shared memory with the R5FSS1_0  core and R5FSS1_1 core. Attached the image.

(unitptr_t)(&gIpcSharedMem[0]);

Above statement is in derived Sys Config file ( ti_drivers_config.c) .

Hey Rapeti,

A shared memory definition between R5FSS1_0 and R5FSS1_1 is required in order for the IPC example to build and execute as expected.

What is the reasoning for disabling this from the default configuration?

If you don't disable this shared memory, do you still experience the error?

I have followed as given in faq-mcu-sdk-build-error-expected-expression-rpmsgparams-vringtxtaseaddr.

 yes even if the shared memory is not disabled i am getting the same error: rpmsgParams.vringTxBaseAddr[CSL_CORE_ID_R5FSS0_0] = (unitptr_t)(&gIpcSharedMem[]); expected expression error for all subsystem cores (R5FSS0_0,R5FSS1_0,R5FSS1_1).

Hey Rapeti,

Thank you for sharing this information. As mentioned by Nick S. on the previous thread you shared: When generating a project that uses multiple cores, you need to build the _system level project and not the specific core version of the project.

Based on the CCS screenshot you shared earlier; you are building the "ipc_rpmsg_echo_am263px-lp_r5fss0-1_nortos" project. Instead, you should build the "ipc_rpmsg_echo_am263px-lp_system_freertos_nortos". The system project configuration will handle building the .out files for each r5fssX-Y core and combine them into a single multicore_elf file to load/debug.

Best Regards,

If i have imported a system project my issue got resolved but, if i have created 2 Core projects using two empty project which are dependent on each other then what is the procedure to make them as system project and to add IPC as communication between them.
