TMDS64EVM: How to change the clock of CA53

Hello Kiyomasa-san,

Thanks for reaching out to Texas Instruments E2E support forum.

Can you please confirm, did you rebuild the libraries and SBL examples after changing the code to set frequency of clock?

Please follow the below steps:

• To build libraries, please run below command from SDK install directory.

gmake -s libs

• To build SBL examples, please run below command from SDK install directory.

gmake -s sbl

Hello Tushar Thakur.

Thank you for your reply.

I didn't rebuild the libraries and SBL examples after changing the code to set frequency of clock.

I installed make for windows from the following.
gnuwin32.sourceforge.net/.../make.htm

I tried the following, but an error occurs.

c:\ti\mcu_plus_sdk_am64x_09_00_00_35>make -s libs
process_begin: CreateProcess(NULL, C:/ti/ccs1240/ccs/utils/cygwin/mkdir -p obj/am64x/ti-arm-clang/release/r5f/board, ...) failed.
make (e=2): ??????????????????
make[2]: *** [obj/am64x/ti-arm-clang/release/r5f/board] Error 2
make[1]: *** [board_r5f.ti-arm-clang] Error 2
make: *** [libs] Error 2

Please tell me how to solve it.

Best regards,

Hello Kiyomasa,

Thanks for your response.

Can you please tell which version of CCS IDE is installed in your system?

It seems like you don't have CCS v12.04 installed at directory C:\ti\ccs1240.

Hello Tushar Thakur.

I installed CCS v12.05. The directory is C:\ti\ccs1250.

How should I fix it?

Best regards,

Kiyomasa Imaizumi.

I tried to change imports.mak below.

DEVICE ?= am64x

ifeq ($(OS),Windows_NT)
    TOOLS_PATH?=C:/ti
    CCS_PATH?=$(TOOLS_PATH)/ccs1250/ccs --> changed
    CCS_ECLIPSE=$(CCS_PATH)/eclipse/eclipsec
    CYGWIN_PATH?=$(CCS_PATH)/utils/cygwin

Is this correct?

Best regards,

Kiyomasa Imaizumi.

However, an error occurred as below.

Can you please tell which version of TI CLANG compiler toolchain is installed in your system?

It seems like you don't have TI CLANG compiler toolchain installed at directory C:\ti\ti-cgt-armllvm_2.1.3.LTS.

Please refer TI CLANG.

To know all the required tools for building the SDK, please refer Install Setup SDK tools.
