CCS/CC2640R2F: OAD for simple peripheral problems

And the very strange thing as for me - i have generated ccs_linker_defines.cmd in stack project, i've added this in linker files/paths for app project, but when linking app project - it says that there are no defines of ICALL_STACK0_START and so on. 

Hello Dmitriy,

Did you compile the stack project first?

Did you follow the simplelink guide to ad Adding OAD to the stack? I did this exercise recently on sdk3.30 which worked well. But you have to follow every step very thoroughly.

Hello Eirik!

Thank you for your answer - yes, i compile stack project first.

Yes, i followed the guide i gave a link to. The guide is for multi role project, so there are some difference in stack part configuration. On screenshots you can see that i say to app part to use link.cmd from stack part, but app part doesn't see it..

And more of that i have problems with these:

undefined first referenced
symbol in file
--------- ----------------
GATT_SendRsp <whole-program>
HAL_SYSTEM_RESET <whole-program>
simple_peripheral_UnRegistertToAllConnectionEvent <whole-program>

Is it becouse of wrong stack configuration?

Maybe it's better to attach my .project files?

Best regards, Dmtiriy.

Hi Dmitriy,

(We do have a simplelink OAD example - maybe it would be easier for you to use this as a starting point and add your custom application on top?)

Please use cc26xx_app_oad.cmd as the app linker command file.

Hello, Marie!

To be honest - my custom application is big enough and i had to use cache as ram option. And as i understand - the offchip oad example project is bigger then base simple peripheral project and have many things that i have cutted in my custom one - so if it is possible it would be pleasure if you can help me to add oad part to my custom project.

Best regards, Dmitriy.

Hello! 

All i wrote above - was my attempts to add oad to simple peripheral in CCS 9.01 version on my laptop.

Today i do all the same exactly from my personal computer with CCS 9.1 version and i have no problems with linker in case of taken dependencies from stack project.

Now i have only one problem of linking, it is:

undefined first referenced
symbol in file
--------- ----------------
GATT_SendRsp <whole-program>

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "simple_peripheral_cc2640r2lp_app.out" not built

How can i fix it?

Best regards, Dmitiry

just for experiment i 've commented gatt_sendrsp where it used and linked and builded the project again.

It successfully builds, but when i try to debug CCS programms my cc2640r2 mcu using my XDS110 debug probe, but after this nothing happens , i have all buttons in debug mode deactivated, i can't see the entry point of project( on screenshot you can see a main from previous debug session ) why does this happens too?

Hi Dmitriy,

GATT_SendRsp() is defined in the BLE library, i.e. it's an ICall API. Did you include icall.h and icall_ble_api.h?Did you call it before ICall_registerApp()?

I don't understand your question, can you please re-phrase.

Hi Marie!

Yeah, i do include icall.h and icall_ble_api.h - maybe that's a reason that i have this error in linker step, not in build.

I call it on SimplePeripheral_processConnEvt - like in standart simpleperipheral example. And at the ICall_registerApp() is the first function i call in  SimplePeripheral_init. So this error with undefined GATT_SendRsp is appears after adding OAD steps, like in guide i've attached. How can i fix it?

The question about debuggin - when i press debug button in code composer studio i have next:

building if necessary 

linking

downloading code to flash

and after that i expect to be able to run the code - but all debug buttons are inactive - looks like debugger doesn't understand where i have main() function.

How to debug this project in such case? I found that all this happens after i add CACHE_AS_RAM option. If i delete this in predefined and linker - i can debug, if i add - i can't. But there was no such problems when i debugged no oad simple_peripheral application - CACHE_AS_RAM doens't affect debugging and working of project. 

And how can i create oad_merged.bin ?

And is it possible and how to add CACHE_AS_RAM option to BIM?

Best regards, Dmitiry.

Hello, Marie!

Are there any possibilities to resolve this problem?

Best regards, Dmitiry.

Hi Dmitry,

Thanks for posting the screen shot. The errors showed are not linker errors but error between CCS and the Debugger. 

What debugger are you using?

Also, can you try using a different USB port?

Can you use Flash Programmer 2 to Mass erase your device and retry?

Hi Marie!

I use XDS110 debugger.

I tried to use different usb ports - no differ.

Yeah, i tried to mass erase via Uniflash and via flash programmer 2 before flashing new oad with cache as ram and it didn't help too.

So when i try to add cache as ram i have this problem, if not - debugger works as usuall.

Best regards, Dmitiry.

Hi Dmitriy,

To use Cache As RAM with oad you will need to change the CCFG in the BIM project. Please see:

Hello, Marie!

Thanks for that post, i saw it when searched for my problem.

So i did next:

1. Add to ccfg of BIM project 

#ifdef CACHE_AS_RAM
  #define SET_CCFG_SIZE_AND_DIS_FLAGS_DIS_GPRAM  0x0 /* Enable GPRAM */
#endif //CACHE_AS_RAM

2. Add to BIM project linker CACHE_AS_RAM=1 , add to app project predefined symbols CACHE_AS_RAM

3. Add to .cmd of BIM project all the code from point 7 of original instruction

4. Add to app project linker CACHE_AS_RAM=1 , add to app project predefined symbols CACHE_AS_RAM

5. Add to main() of app :

#ifdef CACHE_AS_RAM
// retain cache during standby
Power_setConstraint(PowerCC26XX_SB_VIMS_CACHE_RETAIN);
Power_setConstraint(PowerCC26XX_NEED_FLASH_IN_IDLE);
#else
// Enable iCache pre-fetching
VIMSConfigure(VIMS_BASE, TRUE, TRUE);
// Enable cache
VIMSModeSet(VIMS_BASE, VIMS_MODE_ENABLED);
#endif //CACHE_AS_RAM

6. Add to .cmd of app project all the code from point 7 of original instruction

7. Clean all projects - bim,stack,app

8. Build all projects - bim, stack, app

9. Fully erase chip memory

10. Flash and enjoy

After all of this BIM works, but app craches after   BIOS_start();


Where am i wrong? May we ask to come someone of TI guys who have tested cache as ram in oad projects, @JXS, or @YiKai Chen, or @Sean2?

Best regards, Dmitriy.

UPD: updated instruction of adding CACHE_AS_RAM to cc2640r2
 

Hi Dmitriy,

Did you add the CACHE_AS_RAM compiler and linker define to the BIM project? (I would also clean and rebuild the whole project after adding these changes, not just press the build button.)

Hello, Marie!

Yeah, i did it. Sorry that i forgot to write this point. And i cleaned all 3 projects ( bim, stack, app ) and then build them ( bim, stack, app ).

Is it necessary to add code from point 7 of instruction to CMD files of bim and app ?

Best regards, Dmitriy.

Hi Dmitriy,

Yes you will need to alter the linker command file for both the BIM and app (and add the linker define CACHE_AS_RAM=1).
