problem on Rebuild EVM c6678 library with gcc

update:
when i try to replace CGT command to gcc "--include_path=" (in CCS project properties),"--include_path=" is unrecognized in gcc.

how can i change aliases from "--include_path" to "-I" ? (both support in CCS)

Hi Titusrathinaraj 

Sorry for replaying late , I was out of office

thanks for this link  but i need static library (don't need dynamic library)

i import platform_lib_evmc6678 to CCS 5.2

 add compiler path in project properties > c6000 compiler

add and change header file directory

after build project i have error in console : --include_path unrecognized 

i try to change "--include_path" to "-I" in .mk file manually but compiler can't find header file

----------------------------------------------------------------------

i try to use CCS cross compiler but compiler can't use PDK library  (.lib) file (error : can not find library file)

how can i rebuild pdk library or where can i find platform library  for linux c6x ?

(i need access to GPIO and LED using linux c6x on c6678 EVM)

thanks

Ebi

Hi raja

thanks for your replay and sorry for replying late (i was on vacation)

i succeed to use pdk source file for control GPIO but i have problem to control "user LED "

this is my function (compile with c6x-uclinux-gcc)

void fpgaControlUserLEDs(FPGA_UserLed uchUserLEDNum, 
                         FPGA_LedStatus uchStatus)
{
	unsigned char uchValue = 0; /* Default value */
	unsigned char temp;
	unsigned int ret;

    if ( (FPGA_USER_LED0 > uchUserLEDNum) ||
         (FPGA_USER_LED3 < uchUserLEDNum)) {         
         /* No action for the invalid LED numbers */
         return;
    }         

    /* Read the current LED status */
    ret = fpgaReadConfigurationRegister(FPGA_DBG_LED_OFFSET, &uchValue);
    printf ("Status = %d \n" , uchValue);
    if (ret != SUCCESS) {        
    	printf ("Result is Bad \n  ");
    	//IFPRINT (platform_write( "fpgaControlUserLEDs: Error in reading the fpga config reg\n"));
    }


    /* Turn on/off the corresponding LED bit number */     
    switch (uchStatus) {
        case FPGA_LED_OFF:
            temp      = (FPGA_LED_ON << uchUserLEDNum);
            uchValue |= temp;
            break;
        case FPGA_LED_ON:
            temp      = ~(FPGA_LED_ON << uchUserLEDNum);
            uchValue &= temp;            
            break;
        default: /* No action */
            break;
    }

    /* Send command to turn on/off the Corresponding LED */
    ret = fpgaWriteConfigurationRegister(FPGA_DBG_LED_OFFSET, uchValue);
    printf ("Status = %d  \n" , uchValue);
    if (ret != SUCCESS) {        
    	//IFPRINT (platform_write( "fpgaControlUserLEDs: Error in writing the fpga config reg\n"));
    	printf ("Result is Bad \n  ");
    }
    printf ("Result is Good \n  ");

    return;
}

and this is result for Linux (program build without error but not working )

Status = 255
Status = 255
Result is Good
LED off
Status = 255
Status = 253
Result is Good
LED on
Status = 255
Status = 255
Result is Good
LED off
Status = 255
Status = 253
Result is Good
LED on
Status = 255
Status = 255
Result is Good
LED off
Status = 255
Status = 253
Result is Good
LED on

result for same function in CCS project (working correctly):

Status = 0
Status = 2
Result is Good
LED off
Status = 2
Status = 0
Result is Good
LED on
Status = 0
Status = 2
Result is Good
LED off
Status = 2
Status = 0
Result is Good
LED on
Status = 0
Status = 2
Result is Good
LED off
Status = 2
Status = 0
Result is Good
LED on

main file and all of source file is same

can you help me what's wrong in my code ?

thanks

update :

i try to resolve problem

below is spi timing diagram for c6678 EVM (READ operation)

i check spi send / receive data 

send address in CCS project and linux project is same , but receive data for linux project is incorrect :

debug LED register is 0xFF instead of 0x0

why fpga send incorrect data to DSP when i use linux ?

thanks

Ebi

Hi raja

thanks for following

i running linux in "NAND boot"

Hi Raja

sorry for replying i working on other Project

i succesed to use PDK library for control  GPIO:

in ubuntu host => create c project in CCS =>select linux GCC => add most PDK,GCC header and source file and some header file from CCS compiler directory

but i can't use PDK header and source file for control debug LED(spi) i think some initialization  procedure corrupt when i use both PDK and GCC source file 

i hope this post is usefull for others

best regards

Ebi

Hi,

   I am working on 6657 dsp processor and I will have to change the pdk libraries (for a future custom board).

I need to know if exist a document that describe the build procedure as ti.platform.evm6657l.ae66, ti.csl.ae66,

ti.transport.ndk.nimu.ae66 and so on, and if exists where I can catch it.

We will try to remove phy device (sgmii) and I need to study if it's possible and the sw impacts.

I have found some links that describe the pdk demo build or platform_lib but it's not enough.

I use CCS 6.1.3, bios_6_46_00_23, on linux host.

Installed packets:

ti-processor-sdk-rtos-c665x-evm-03.00.00.04-Linux-x86-Install.bin

CCS6.1.3.00034_linux

bios_setuplinux_6_46_00_23.bin

Best Regards,

Dario

Hi

in this post , i try to rebuild PDK with c6x-uclinux-gcc for Linux-c6x but i understand that you try to  edit PDK and rebuild library for CCS (cl6x) in Linux environment  .

i hope this link be useful :

(i think if you create new thread, TI employee can help you better )
