TMDSEVM6678: LINKER ISSUE

Thilak Ram

Part Number: TMDSEVM6678

Hi,

I am using C6678,In that after code build the linker command is getting auto generated since it is in RTGS, I have to use

and add the linker file to change the L2SRAM memory location.Pls clarify on how to add the linker command instead of auto generating linker cmd or modifying it.

Regards,

Thilak

Thilak,

This question seems to be a generic one on CCS.

Notifying to George Mock.

Alternatively, all the 56 PDK examples listed in this FAQ are "RTSC-based-applications" ----> example programs.

[FAQ] TMS320C6678: How to generate the CCS PDK examples for C6678? - Processors forum - Processors - TI E2E support forums

They are all RTSC applications with "*.cfg" as configuration settings.

You can have any one of those examples, say ... UART as a base project; with its settings and environment, modify for your app according to your needs.

In that way, it is good to start with something already working.

The platform test program in the PDK package is the "only-one--- non RTSC", bare metal code with just the linker.cmd file, "platform_utils.cmd"; Without any *.cfg.

Shankari,

My query is whether we can modify the location in the linker.cmd file which is an rtsc project.

Thilak,

In RTSC project, the linker.cmd is an autogenerated one. The linker.cmd will be present at "C:\ti\pdk_c665x_2_0_16\packages\MyExampleProjects\UART_BasicExample_C6657_c66xTestProject\Debug\configPkg\linker.cmd"

We shall modify but when you use the "clean-option" of the project, the complete, "configPkg" folder will get deleted.

When you re-build, the linker.cmd will be created with *.cfg as input. ( The *.cfg will be located at C:\ti\pdk_c665x_2_0_16\packages\ti\drv\uart\test\c6657\c66\bios\uart_test.cfg )

Ok.Ok i trying to build using UART DMA PROJECT.I am able to build it but i am getting the following error while loading the program in the board

C66xx_0: File Loader: Verification failed: Values at address 0x84000000 do not match Please verify target memory and memory map.
C66xx_0: GEL: File: C:\Users\tp\workspace_v9\UART_BasicExample_C6678_c66xDMATestProject\Debug\UART_BasicExample_C6678_c66xDMATestProject.out: a data verification error occurred, file load failed.

I tried renistalling and importing it. Also i have to use dma transfer function to access emif transfer having this code as a base.

Please check into this error.

Regards,

Thilak

Thilak,

Are you facing problem while running the gel file or while importing the UART-DMA example into CCS?

Please upload a video file of your experiment. So that it will be easy to solve the problem quickly.
