66AK2H14: Compiling processor sdk rtos k2hk 6 03 00 106 - demos bigdataipc from command line. Getting uses VFP register arguments error

Good day

I'm trying to build the bigdataipc demo from the command line using make.

I updated the products.mak file with the following changes:

PLATFORM = TCI6636

#### BIOS-side dependencies ####
BIOS_INSTALL_DIR       = $(DEPOT)/bios_6_76_03_01
IPC_INSTALL_DIR        = $(DEPOT)/ipc_3_50_04_08
XDC_INSTALL_DIR        = $(DEPOT)/xdctools_3_55_02_22_core
PDK_INSTALL_DIR        = $(DEPOT)/pdk_k2hk_4_0_16/packages

#### BIOS-side toolchains ####
gnu.targets.arm.A15F   = $(DEPOT)/ccs930/ccs/tools/compiler/gcc-arm-none-eabi-9-2019-q4-major
ti.targets.elf.C66     = $(DEPOT)/ccs930/ccs/tools/compiler/ti-cgt-c6000_8.3.5

I also had to edit the top-level makefile and removed the ifdef's to just have the TCI6636 values (else the make did nothing...) and then compiled. It fails with the following line:

ti/ccs930/ccs/tools/compiler/gcc-arm-none-eabi-9-2019-q4-major/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld: error: bin/evmK2H/release/app_host.xa15fg uses VFP register arguments, /home/christo/ti/ccs930/ccs/tools/compiler/gcc-arm-none-eabi-9-2019-q4-major/bin/../lib/gcc/arm-none-eabi/9.2.1/libgcc.a(_udivmoddi4.o) does not

First off, what is VFP? I'm building towards an app that will be using hardware floating point, if that is related.

Any feedback would help.

Kind regards

Hi, Christo,

I don't think big data example is supported on K2H platform, nor has it built or tested on K2H. The big data example is not included in the K2H Processor SDK release. Where did you get the example from?

It got installed with processor_sdk_rtos_k2hk_6_03_00_106. Under demos

Kind regards

Hi, Christo,

I'll have the RTOS expert to take a look at it. However, he is out of office till 8/31, so response will be slow.

Thanks Rex

I have created a new post here https://e2e.ti.com/support/tools/ccs/f/81/t/935269 talking about a similar and may be related problem and how I fixed it in CCS. Looks like the compiler is using -mfloat-abi=hard but the linker not. I did try and add it to the makefile for the host as part of the linker tags but it did not seem to work. I'm not a master makefile guru, but maybe it will point the RTOS expert (or maybe the GNU 9.2.1 compiler expert?) into the right direction.

Kind regards

Christo

Hi, Christo,

I closed that one and let all responses on one thread so knowledge be kept in one thread and easy to be searched by futre users facing the same issue.

Hello Christo,

The big data ipc demo can be built using the top-level makefile. You should not have to edit products.mak file, the setupenv script will setup the environment variables for you.

Please refer to the build instructions here: http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_examples_demos.html#id44

Hope this helps. Let me know if you have any questions.

Regards,
Sahin
