RTOS: AM335x project compilation issue

Attila Csosz

Tool/software: TI-RTOS

Hi,

I've successfull tested GPIO_LedBlink_skAM335x_armTestProject. Now I'd like to add some modifications in c:\ti\bios_6_52_00_12\packages\gnu\targets\arm\rtsv7A\startup.c

I've made the modification and I tried to recompile the PDK (by using )

The only difference I missed 'gmake clean' and the examples generation. I also recompiled my project in CCS.

The problem: after recompilig nothing changed in the binary also only the "*.a" files are changed in PDK so probably startup.c not compiled.

What may the problem?

The RTOS team have been notified. They will respond here.

Attila,

Yes, please try a $gmake clean first, and report back if this helped.

But I don't want to do the long compile process it takes hours.

I assume I have to compile gnu.targets.arm.rtsv7A.aa8fg. Its date 27 jul 2017 so it is not compiled during the PDK compile process.

The example is a TI example.

From the linker.cmd:

"C:\ti\bios_6_52_00_12\packages\gnu\targets\arm\rtsv7A\lib\gnu.targets.arm.rtsv7A.aa8fg"

Hi Attila,

First I'm assuming you know how to rebuild SYS/BIOS (documented in the SYS/BIOS User Guide). To minimize build time, you can edit the bios.mak file in the root of the product and remove the XDCARGS targets you are not interested in. This will greatly reduce the rebuild time.

The problem gnu.targets.arm.rtsv7A.aa8fg remains unchanged in the build process and I'd like modify startup.c .

Attila,
can you post the complete output after you execute 'gmake -f bios.mak'? Usually, gmake is not going to miss that a source file has changed and that a library needs to be rebuilt, but I would like to see the output to check for something unusual.

The rebuild process might take 15-20 minutes and the output is long, so just zip up the output and attach it to your post.

My problem is similar (part of building because of startup.c)

e2e.ti.com/.../280764

I tried 'xdc clean; xdc' in 'c:\ti\bios_6_52_00_12\packages\gnu\targets\arm\rtsv7A\' but I've got the following messages

c:\ti\bios_6_52_00_12\packages\gnu\targets\arm\rtsv7A>xdc
making package.mak (because of package.bld) ...

How to fix that...

Attila,
try to build from the top of the SYS/BIOS installation, as desribed in SYS/BIOS User Guide, in the Appendix Rebuilding SYS/BIOS. It takes longer but all the dependencies, including the compiler's path that caused your error, are automatically taken care of.

I'm trying to rebuild SYS/BIOS using SYS/BIOS User Guide ( the Appendix Rebuilding SYS/BIOS). I've got the following messages when call 'gmake -f bios.mak' (I've called before 'gmake -f bios.mak clean'). I've attached my modified bios.mak (rename it from bios.doc, the forum engine doesn' allow upload the mak file)bios.doc

So, have you checked that path? Is there a GCC compiler there?

0 Attila Csosz over 8 years ago in reply to Sasha Slijepcevic

Intellectual 710 points

Yes, the compiler is there.
I've checked the C:/ti/copy_bios_6_52_00_12/packages/ti/targets/arm/elf/IArm.xs file but it seems it doesn't accept the arm-none-eabi compiler (which is CCSv7 default)

0 Sasha Slijepcevic over 8 years ago in reply to Attila Csosz

TI__Mastermind 37985 points

I just checked your bios.mak. You are supplying a GCC compiler where you are supposed to supply a path to a TI compiler. Which one of these do you want to use?

0 Attila Csosz over 8 years ago in reply to Sasha Slijepcevic

Intellectual 710 points

I'd like to use the gcc compiler (arm-none-eabi)

0 Sasha Slijepcevic over 8 years ago in reply to Attila Csosz

TI__Mastermind 37985 points

Then you need to assign the compiler path to one of the gnu.targets, depending on the device and the platform.

0 Attila Csosz over 8 years ago in reply to Sasha Slijepcevic

Intellectual 710 points

I think I have assigned

(from my bios.mak)
gnu.targets.arm.A8F ?= c:/ti/ccsv7/tools/compiler/gcc-arm-none-eabi-6-2017-q1-update

0 Sasha Slijepcevic over 8 years ago in reply to Attila Csosz

TI__Mastermind 37985 points

I see, I only noticed the assignment to a TI target. You have to remove that assignment to a TI target, that's where the errors are coming from.

0 Attila Csosz over 8 years ago in reply to Sasha Slijepcevic

It means I can build only the gnu targets? These are a small part of the SYS/BIOS. Also the PDK build (which builds the SYS/BIOS also) uses the gnu compilers.

0 Sasha Slijepcevic over 8 years ago in reply to Attila Csosz

TI__Mastermind 37985 points

You can rebuild SYS/BIOS for as many targets as you want, but for TI targets you have to use TI compilers, and for GNU targets GNU compilers.
