AM263P4: Real time debug with UART issue

ARJUN RAVEENDRANATH

Part Number: AM263P4
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hi All,

I am trying to enable real time debug by following AM263Px MCU+ SDK: Enabling Real Time Debug

I am unable to get it to work.

I have created a sample project. A simple count variable is incremented in while loop. 

As shown in pic, Error: “Target failed to read memory “ and “Malformed response packet” appears.

Attaching the project as well here.

Kindly help in resolving issue.

    Hi Arjun,

    Thanks for sharing your project, I will try the same on my end. Meanwhile, can you please let me know the Syscfg and the SDK version you are using for the AM263Px

    Hi Arjun

    Sharing my findings below:

    1. I used the example shared by you above, imported it in CCS, built it. I reduced the sleep to a few microseconds instead of seconds.

    2. Created a target configuration as explained in the documentation. 

    3. Then launched the above config and connected the R5F core (make sure the UART_connection_0/cortex_r5f_0 is running). Load the .out file to R5 0 core, execute,

    4. In expressions window, add "count" and click on the "enable continuous refresh" button.

    With the above steps I was able to see the continuous refresh working and updating continuously.

    At 2 seconds, it is causing a read time out which Im . May I know if you really need the ClockP_Sleep(2)? The Real time debug works without any intermediate sleep as well. Seems like the CCS has some UART timeout setup which gives the read timeout error. I will have to check with our tools team on this. But meanwhile, you can continue using it by reducing sleep to us or removing the sleep.

    Hi Shaunak,

    Thanks for the detailed reply.

    sysconfig ver: 1.20.0

    SDK ver: 9.2.0.56

    I have tried again but not successful. However, now the error msg is different. "Read Time out" Please see image.

    I have tried to increase refresh rate for expressions watch window but no changes.

    I have a doubt regarding Step 3 you mentioned.

    3. Then launched the above config and connected the R5F core (make sure the UART_connection_0/cortex_r5f_0 is running). Load the .out file to R5 0 core, execute

    As soon as i launch the target config, status is as below: Only UARTConnection_0 shows as running. And i load the .out file to this target

    Is this correct? am i missing something?

    Kindly help in resolving this issue.

    Thanks,

    Arjun.R

    1. As soon as you launch your target config, the UART connection is running by default (expected behavior).

    2. In the above findings I shared, I let this UART core run, I connect my R50 core and load my program here.

    3. Then execute the core R5F0.

    4. Then load the symbols on the UART core.
