TMDSLCDK6748: C6748 LCDK Debugging Issue

Hi,

The C6748 LCDK does not have onboard emulator, as mentioned in the User's Guide, section 1.1 Features:

• 14-pin JTAG header (No onboard emulator; external emulator is required)

Regards,

Okay.

I want to make an audio in and audio out sample code. Just like this example code designed for OMAP-L138 Experimenter Kit present in "Digital Signal Processing Application on the Texas Instrument C6748 Processor" Book. 

#include "L138_aic3106_init.h"

 interrupt void interrupt4(void) {
 uint32_t sample ;
 sample = input_sample ( ) ;
 output_sample ( sample ) ;
 return ;
 }

 void main ( void) {
 L138_initialise_intr(FS_48000_HZ , ADC_GAIN_0DB, DAC_ATTEN_0DB) ;
 while ( 1 ) ;
 }

But for C6748LCDK or OMAP L138 LCDK, there is no such header file like "L138_aic3106_init.h" that can be included. If this header file is for EVM, then for LCDK, which header file for CODEC initialization could be used. 

Meanwhile, I have added following files:

In include options, I have added:

"C:\ti\C6748_Files\pdk_C6748_2_0_0_0\C6748_StarterWare_1_20_03_03\include\c674x\c6748"
"C:\Program Files (x86)\Texas Instruments\C6000 Code Generation Tools 7.3.1\include"

And in File search path, I have added following files:

"C:\ti\C6748_Files\pdk_C6748_2_0_0_0\C6748_StarterWare_1_20_03_03\binary\c674x\cgt_ccs\c6748\lcdkC6748\platform\Debug\platform.lib"
"C:\ti\C6748_Files\pdk_C6748_2_0_0_0\C6748_StarterWare_1_20_03_03\binary\c674x\cgt_ccs\c6748\drivers\Debug\drivers.lib"

Are these files enough or should I add some more files? Also i could'nt find any audio example running on LCDK. Could you please refer me, If any.

Hi,

Processor-SDK for OMAP-L137 has a demo of audio-preprocessing which should be portable to OMAP-L138. After you download and install the SDK, the demo is located at processor_sdk_rtos_omapl137_6_03_00_106\demos\audio-preprocessing.

okay, I have downloaded and installed SDK that you recommended. In audio-preprocessing folder, I found some examples but that are bios based. I am very new of OMAP-L138 LCDK and C6748 LCDK. So, I am in learning and exploring phase. Please guide me about implementation of audio processing examples that are not bios based. I will be very grateful to you.

Thanks!!!

Thank you for providing me the starting point. I'll run these projects as you recommended. 

Hi,

I have run these commands that you mentioned. But I am facing an error. Please help me and provide the solution.

Also, I have tried by adding environment path variables found by running setupenv.bat command, in system environment variables. But still the error is not solved. 

The variables the I have added are:

SDK_INSTALL_PATH : C:/ti/omap
PDK_INSTALL_PATH : C:/ti/omap/pdk_omapl138_1_0_11/packages

Hi,

Please try to install the SDK to C:\ti instead of C:\ti\omap. Due to Windows limitation, directory path may be over the limit if you install the SDK to C:\ti\omap.

Regards,

Jianzhong

Hi, 

I have tried by installing the OMAP SDK in the path that you mentioned, i.e C:\ti. But still the error remains same. 

The output of the commands is given below. Please suggest me what to do now. Thanks!!!

Okay, Thank you for info.

Okay, I will try with CCS 9.3 and then let you know the result.
