cc2538SF23 icf settings

Hello Giuseppe,

Thre are few changes required along with changing the linker file CC2538.icf. I will provide you the modified file tomorrow. 

Regards,

i've copied the icf of another project, but with this i've 100 KB:

hi, thanks for ypur answer, sorry but i don't understand what you mean:

Suyash Jain said:

Also ensure that the device descriptor file within the Debugger category in this window is for correct device. 

i've changed the device with TexasInstruments CM2538SF53 and copied the code in the file you linked in tools/cc2538.icf,so now? what else should i do?

thanks again

edit:
 done, thanks!!

sorry, but the program seems to lock at the instruction MAC_RADIO_TIMER_WAKE_UP, could it be a problem of the radio? i'm using a custom board with a pcb antenna designed like the one on cc2538EM

Hello Giuseppe, Were you able to resolve the issue?

hi Suyash, no, could it be an hardware issue? or sbout compiling problems(the original program was for the SF53)? I'm making a new board to try the radio section.

thanks for your help!!

Hi Giuseppe ,

I am also facing same issue. 

We are currently using Evaluation module CC2538EM of TI for development purpose which is having CC2538SF53(512k flash) Controller on it.

And firmware of our project is developed on same evaluation board, which needs to be migrated now to  our custom board which is having  CC2538SF23(256k flash) controller on it.

As per your guidelines we have modified icf file in firmware of CC2538SF53 controller and tried to flash the code in CC2538SF23 controller through IAR debugger.

But we are getting error messages as below,                                                                                               

Unloaded macro file: C:\Program Files (x86)\IAR Systems\Embedded Workbench 7.2\arm\config\flashloader\TexasInstruments\FlashCC2538.mac

The flash loader program reported an error.

If you have resolved issue Please let me know the changes. 

Thanks,

sagar
