Contiki example with TI arm compiler.

Other Parts Discussed in Thread: CC2650

I was able to compile contiki hello-world example using TI ARM compiler v15.12.3.LTS.

But that seems not working correct.

Following shows steps to build.

1. To get list of source files and options, run `make --dry-run`.

make --dry-run TARGET=srf06-cc26xx BOARD=sensortag/cc2650 > log

2. Parse log file using python script ( gist.github.com/.../bad5ebebb0b4674902b42b478ee9784d )

python contiki_make_log_parser.py log > sources

This python script generate `option.cmd` file and output list of source files to stdout.

3. Create CCS Empty project.

Create empty ccs project with TI v15.12.3 compiler. Then copy source files to project directory except startup_gcc.c .

Instead of startup_gcc.c, copy startup_ccs.c from TI RTOS install path.

cp `cat sources` /path/to/prj/dir
rm /path/to/prj/dir/startup_gcc.c
cp /path/to/ti/rtos/dir/product/cc26xxware/startup_files/startup_ccs.c /path/to/prj/dir

4. Modify sources and headers.

4.1 contiki/core/sys/cc.h

Add following to contiki/core/sys/cc.h

#ifdef __TI_COMPILER_VERSION__

#ifndef CC_CONF_INLINE
#define CC_CONF_INLINE __inline__
#endif

#define CC_ALIGN(n) __attribute__((aligned(n)))

#endif

4.2 /path/to/prj/dir/contiki-main.c

Replace from "nop" to " nop" in fade function.

4.3 /path/to/prj/dir/contiki-watchdog.c

call ti_lib_watchdog_stall_enable() in watchdog_init function.

void
watchdog_init(void)
{
  ti_lib_watchdog_stall_enable();
  ti_lib_watchdog_reload_set(CONTIKI_WATCHDOG_TIMER_TOP);
  lock_config(LOCK_REGISTERS_UNLOCKED);
}

5. Add option.cmd to command file

Open Project Property -> CCS Build -> ARM Compiler -> Advanced Options -> Command Files.

Then add /path/to/option.cmd.

6. Build project.

Finally, run build project.

Debugging with XDS seems work. But without XDS debug, firmware stop during booting contiki.

Firmware stops after showing "TI CC2650 SensorTag".

I think some compiler options or linker options are lacked.

Is there a any idea to figure out cause of problem?

As I know, there is bug in TI ARM compiler v15.12.3.LTS so it's not recommended to use it to build BLE example and it might be the cause of your problem. You can try to use TI ARM compiler v5.2.6 which is recommended.

I tried TI ARM compiler v5.2.6. But I got same result.

When I start debug as code composer debug session, I execute with "step over". it seems work fine.

Uart shows me "Hello World"

When source stepping, interrupts are disabled. So I think interrupt related something is wrong.

I have attached my buildable project file. It doesn't contain contiki sources.

To build project, place contiki sources to same directory.hello-world.zip

I forgot a patch for contiki.

Please replace core/sys/cc.h with attached file. cc.h

I've solved this problem.

Interrupt vectors were not set correct.

I added following lines to startup_ccs.c and change IntDefaultHandler, contiki example works perfectly!

extern void GPIOIntHandler(void);
extern void AONRTCIntHandler(void);
extern void UART0IntHandler(void);
extern void TRNGIntHandler(void);
extern void RFCCPE1IntHandler(void);
extern void RFCCPE0IntHandler(void);

Hi,

Good and interesting work.

Can you share the detailed procedure?

Have you tried more complex project?

Are you using Linux OS?

Is it possible to do it under Windows?

Hi Jan,

Basic ideas are in my first post above.

Another example, cc26xx-web-demo with sensortag/cc2650 works fine.

I use Linux, but only use make and python. So I think you can compile in Windows.

My python scripts are incomplete. I'm upgrading my scripts now.

I'll upload them later.

I created contiki and cc26xxware branch for TI ARM compiler.

contiki: github.com/.../contiki branch: arm_compiler

cc26xxware: github.com/.../cc26xxware branch: cc2650_ccs

Python script is in my gist https://gist.github.com/kimura-synthesis/366bdb7fdb5571f681f5555305f13596

Building cc26xx Example in Windows:

1. Checkout my branches

2. Run gmake --dry-run in contiki/examples/cc26xx

gmake --dry-run TARGET=srf06-cc26xx BOARD=sensortag/cc2650 > log

3.Run make_log_parser.py

python make_log_parser.py --fout-type='WIN' --output=files.bat --command=option.cmd log

This script generates files.bat and option.cmd

files.bat: WIndows batch script for copying source.

option.cmd: list of include_path and predifinition for compiler

4. Create Empty CCS Project for CC2650 with TI ARM Compiler v5.2.6, TI v15.12.1.LTS or TI v15.12.3.LTS

notice: TI v16.6.0.STS compiler has problem with assembly code.

5. Copy files.bat to project directory.

6. Run files.bat

7. Add option.cmd to Command Files

Open Project property, then select CCS Build -> Advanced Option -> Command Files.

Next, add options.cmd to Command Files.

8. Run build.

Regards,

Cool and Thanks for sharing this. By the way, are you able to trace/debug Contiki example step by step using CCS?

0 KazunoriKimura over 8 years ago in reply to YiKai Chen

Prodigy 150 points

Trace/Debug is going well at the moment.

Breakpoints, step by step execution, variables and registers views are works.

I've attached my screenshot in debug session.

Cool! I would definitely like to try this when I can. Thanks again!

I take it back.
Trace functions don't works. I think it still lacks driver for TPIU.

Thanks for sharing. Will try it soon.

where exactly in TI RTOS path can I find "startup_ccs.c"
i found multiple files with same name.
but i ended up using it from "C:\ti\tirex-content\tirtos_simplelink_2_13_01_09\products\cc26xxware_2_21_01_15600\startup_files"

I'm trying to build the project but I'm getting error with message
"Buildfile generation error occurred..
This project does not contain a buildable RTSC Configuration (.cfg) file. In order for it to build, this project must contain one RTSC Configuration file that is not excluded from build.
Build stopped.."

Please guide.
