AM68: Software tools to generate source files

Francisco Vera
Prodigy 120 points

Part Number: AM68
Other Parts Discussed in Thread: SYSCONFIG, , HALCOGEN, TDA4VL, TDA4VM-Q1, DRA829J-Q1, DRA829, TDA4VM

Hi, I am finding a software tool that generates the source files for the AM68 processor. The only tool that I have been able to get is SysConfig. However, this software does not generate any source file for this processor.

I need these files to study and develop the firmware of the MCU (ARM-R5F).

Is there any example that provides these source files? Is there a software tool for the AM68 processor similar to the Halcogen software for the RM46 microcontroller?

    >>  Could you tell me what the meaning of the MCU concept 

    The J721S2, TDA4AL, TDA4VL, TDA4VE, AM68A Technical Reference Manual (Rev. C) has a chapter 6 where this is explained in detail. Suggest reading the 6.3 Dual-R5F MCU Subsystem which explain how it is tied to to over SOC architecture.

    Indeed, the word MCU corresponds to microcontroller, I'll give you a screenshot of the user guide page where it appears (corresponds to the link you sent me). I was right, I don't understand why you, who are experts, have made me doubt. I feel that the support is being a real shame and I notice that you have no intention of helping me. I ask you again: How could I contact the local Texas Instrument support for Spain, please?

    Please I would like to not continue wasting time.

    Hi,

    Which is your objective to send me this information?

    At the beginning of the post I already knew that the term MCU referred to microcontrollers and that they were isolated and communicated with the processor as shown in the following figure. However, you were the one who questioned all this.

    I don't understand what this response of yours is about now.

    If what you mean by the term closed box is that the microcontrollers (MCU) of the AM68 processor, the user cannot develop firmware layers for them, then it would be a real nonsense and waste of the hardware capabilities of this processor .

    Hi Francisco:

    Unfortunately it seems I cannot respond to your latest thread, something got messed up. But I want to add in that we have received your feedback, and we have a task in our execution backlog to implement a more accessible MCU via software in the future for AM68.

    In the meantime as you pointed out, we have other devices like AM62, AM64 that support this properly. Transparently, only firmware builder (which enables  FreeRTOS + driver functionality on the R5F) is available on AM68 today, and that is our standard suggestion.

    Thank you for the request and feedback.

    I need a processor with ARMv8-A. Therefore, the processors like AM62 or AM64 could be useful to me, but these devices have not ARM Cortex-A72 cores. Do you offer firmware support to DRA829J-Q1 and TDA4VM-Q1 processors?

    Best regards,
    Francisco.

    Hi Francisco:

    You are right, AM62 and AM64 have Cortex-A53 instead, which still falls under ARMv8-A.

    TDA4VM and DRA829 do have RTOS firmware support for the R5Fs, as mentioned earlier in the thread it can be found: https://www.ti.com/tool/download/PROCESSOR-SDK-RTOS-J721E/09.01.00.06. The user experience might be slightly different from AM64, as pointed out. Standardizing this look and feel would be something we are looking at for the future.

    That is, the support that you offer for the TDA4VM and DRA829 processors is the same as for the AM68. In other words, there is no type of support for the firmware layers of the MCUs of these processors. Despite this, could firmware layers of the processor's MCUs be developed that are compatible with the firmware layers of the FreeRTOS operating system or is the policy that you have implemented for these processors basically limiting the functionalities of a high-performance processor?

    Hi Francisco:

    Processor SDK RTOS for DRA829/TDA4VM provides drivers (with source code) and abstraction layer that works with FreeRTOS. Have a look at the PDK and some of the examples in that SDK. There are existing use-cases of using the R5Fs in this device for real-time processing in an application.

    Hi Wallace,

    Thanks for your reply. If there are examples, even with freeRTOS, they would undoubtedly help me with programming the firmware of the processor's MCUs. What I would like to ask you is if there is an example that can be run and debugged from code composer studio.

    best regards,

    Francisco.

    Hi Francisco:

    I believe these are what you'd be looking for. Once you download the SDK, here is an example path to find a FreeRTOS example running on the R5F cores: ti-processor-sdk-rtos-j721e-evm-09_01_00_06  -> pdk_jacinto_09_01_00_22 -> packages-> ti-> drv -> udma-> examples -> udma_memcpy_test

    Hi Wallace,

    The information that you send me it is fundamental. The only thing that I need is the process to import and run this example in Code Composer Studio. Could you give me a tutorial about this?

    Best regards,

    Francisco.

    Hi Wallace,

    Thank you. With this information, I can carry out tests and verify the processes.

    Best regards,

    Francisco.
