Other Parts Discussed in Thread: CC2538

Hi every one,

I am using cc2538 with ccsv5 on ubuntu 12.04 for contiki based project.Since cc2538 is based ARM CORTEX M-3 with 32 bit risc architecture .I kept designated code state as 32 bit in cssv5 processor oprtions.But while compiling it gives error saying as "Option -mv=7M3 is not valid without --code_state=16 "..

Please let me know is it correct is set as 32 bit or 16 bit. what is that designated code state.

Thanks in advance,

Jagas

Hi,

Isn't there any option for "Auto"?

Cortex-M3 devices only support Thumb2 instructions. You don't need to use --code_state at all. If you want to use it anyway, you must write --code_state=16.

Thanks and regards,
