TMDX570LC43HDK: TMDX570LC43HDK

Part Number: TMDX570LC43HDK
Other Parts Discussed in Thread: HALCOGEN

Dear Sir/Madam,

We have purchased TI TMS570LC43HDK demo board. 

we are working on microcontroller based project using C language.

We successfully generated code using HalCoGen tool and tested LED blinking using PWM demo project. 

Next we generated same LED blinking using PWM demo code for GHS(Greenhills ) tool.

we copied this code in to Greenhills IDE project and downloaded successfully.

 

But the generated code is not working and crashing at file HL_het.c file line 1324 during the execution of memcpy().

 

(void)memcpy((void *)hetRAM1, (const void *)het1PROGRAM, sizeof(het1PROGRAM;

 

I am trying to debug the issue and I need TI support to move forward.

 

Share If any document is available on how to adapt TI code to GHS Multi.

 

Pls revert to me if any more information is required.

Regards

Shanmugam

    HI Shanmugam,

    You said that the project is compiled and download to MCU flash through GH IDE, right?

    Do you have changes to HALCOGen generated code: linker cmd file, and other assembly code?

    I think that the following code in HL_sys_core.asm should be removed:

            .bss

            .org    0x08000000+0x00001000+0x00000100

    __ghsend_stack::

    Hi QJ Wang,

    Thanks for your suggestion. we received this suggestion from GreenHills earlier. Apart from this we didnot do any other changes to HALCOGEN generated code. 

    I tested the code by commenting the HL_sys_core.asm file as this was giving compilation error. 

    But the after downloading the LED blink is not working. 

    Hello world example executes successfully without any issue (HL_sys_core.asm  files also does not give below error) 

    its only when we try LED or any peripheral test we don't get any result.

    Thanks & Regards

    Shanmugam.

    Hi QJ Wang,

    I am really sorry. we made changes to HalcoGen generated code as per the below link

    https://www.youtube.com/watch?v=tsVmpH6Pm2U

    At around 5:00 min, the changes are described. 

    But first I tested this example using code composer and LED is blinking.

    I created next project by selecting the GHS tools in project creation and generated the code.

    After generating the code I made same changes as in the example given.

    Thanks & Regards

    After removing the following code from HL_sys_core.asm, does the LED blink using GHS IDE and compiler?

            .bss

            .org    0x08000000+0x00001000+0x00000100

    __ghsend_stack::
