Problem:

**** Build of configuration Debug for project adcVoltMeasure ****

C:\ti\ccsv5\utils\bin\gmake -k -j 4 -s all

'Building target: ../../../../../../../binary/armv7a/cgt_ccs/am335x/evmskAM335x/adc/adcVoltMeasure.out'

'Invoking: ARM Linker'

"../AM3358.cmd", line 24: error: DDR0 memory range overlaps existing memory

range DDR_MEM

error: errors encountered during linking;

>> Compilation failure

==============================================================================

Question:

I have tried to follow the setup insructions under "Setting Up The Tool Chain" under

http://processors.wiki.ti.com/index.php/StarterWare_Getting_Started_02.00.XX.XX#Host_platform_Requirements

but I think I have missed something. "Cygwin" does not seam to be being called. PATH=??? (not sure where I should point it)

Any pointers would be greatly appreciated,

Hi Scott,

Can you share your "AM3358.cmd" file? It seems that the DDR0 and DDR_MEM are overlapping due to improper range.

Hi Radhesh,

I'm using the code from the "example" unmodified as below. I made the assumption (maybe wrong) that it would just work...

Best Regards,

Scott

Hi Scott,

I am not sure how much this would help, can you try commenting out DDR0 because it is not getting mapped to any of the sections in your command file, but looks like already DDR_MEM is used somewhere in your SDK/package and is conflicting resulting in linking error. You can search for DDR_MEM in your s/w and see why conflict occurs.
