tiva c series mcu tm4c129xnczad -iot application

Thank You  

Hi Sai,

I have made the suggested changes in the Files as suggested in the fourm. I was able to build successfully for EK-TM4C1294XL.

BUT....Since i am working with DK-TM4C129X

I made the following changes:

(a) Replace the labels PART_TM4C1294NCPDT and TARGET_IS_TM4C129_RA1 with
PART_TM4C129XNCZAD and TARGET_IS_TM4C129_RA0 in the project settings.
(b) Uncomment the line that defines the label DK_TM4C129X in the enet_s2e.c file.

(c) In properties -->ccs general-->Changed the variant and connection to tm4c129xnczad and stellaris icdi---since it dint get updated automatically

(d)still showed error during build regarding pinoutset() function. The pinout.c file in the driver was still linked to the ek-tm4c129xl. So in pinout.c properties --> resources I changed the location as SW_ROOT\examples\boards\dk-tm4c129x\drivers\pinout.c .

(e)During build am facing the following errors

(f) Made the following changes in enet_s2e.c

#ifndef DK_TM4C129X
    PinoutSet();
#else
    //PinoutSet(true, false);
#endif

(g)  Made the following changes in tm4c129xnczad.cmd

MEMORY
{
//FLASH (RX) : origin = 0x00000000, length = 0x00100000
// SRAM (RWX) : origin = 0x20000000, length = 0x00040000
}

and

//__STACK_TOP = __stack + 512;

(h) Deleted the file startup_ccs.c as there were issues regarding multiple declarations in startup_ccs.c and tm4c129xnczad_startup_ccs.c

(i) changed __STACK_TOP = __stack + 4096; to __STACK_TOP = __stack + 512;  I am not sure if that was needed.

Now I don't have errors, but i am doubful if this the right thing to do in terms of the utility of the application.

Could you help me regarding this

Thanks a lot

Hi Sai

I have made the changes as you have suggested but I'm still facing errors.

The function PinoutSet(); shows error as its still linked to ek-tm4c129xl. Also  the targetcongif file still show tm4c129ncpdt as the part .

Thanks

Hello Ayswaria,

I just followed the steps in my earlier post and now the application builds for DK-TM4C129X board.

When using the DK-TM4C129X board, the line PinoutSet(true, false); should be included. Looks like you did not uncomment the line that has the code

#define DK-TM4C129X

Make sure you also copy "enet_s2e" to the folder "./examples/boards/dk-tm4c129x" and then import to CCS.

Thanks,

Sai

Hi sai

I had uncommented that line as mentioned in the document.

#define DK-TM4C129X

But I had made an edit on this line as:

#define DK_TM4C129X

Because in the latter part of the enet_s2e program this was the varible used.

It builds successfully if that edit is not made.

But the pinoutset and targetconfig file is not linked to dk-tm4c129x.

Thanks,

Ayswaria
