Part Number: TMS320C6678
Tool/software: Code Composer Studio
Hi.
I develope a TMS320C6678 in OpenMP project type.
- CCS 6.11
- MCSDK 2.1.2.6
- OpenMP Runtime 2.x library 2.1.16.3
; RTSC tab window ... platform selected "ti.runtime.openmp.platforms.evm6678"
- IPC 1.24.3..32
- PDK 6678 1.1.2.6
- SYS/BIOS 6.33.6.50
My source code is ...
int main (int argc, char *argv[])
{
uint32_t CoreNUM = 0;
CoreNUM = platform_get_coreid();
TestOMP(); // ###>> OpenMP example code
if(CoreNUM==0){
platform_uart_init();
platform_uart_set_baudrate(115200);
platform_write_configure(PLATFORM_WRITE_UART);
platform_write(">> Test Console start\n");
}
BIOS_start(); /* does not return */
return 0;
}
>> debug window status at Load program (Core 0 is suspend status, Other core Running)
[Question1] Is corrent load program status at OpenMP project type???
OpenMP example code execution status is good. But serial port execute status is wrong. (Only One character output and stop)
> Include header file is ...
#include <ti/platform/platform.h>
#include <ti/platform/resource_mgr.h>
> Pre-define
SOC_C6678
DEVICE_C6678
> include lib file is
ti.platform.evm6678l.ae66
ti.csl.ae66
> Include my *.cfg file contents
var ti_csl_Settings = xdc.useModule('ti.csl.Settings');
ti_csl_Settings.useCSLIntcLib = true;
var PlatformLib = xdc.loadPackage('ti.platform.evmc6678l');
Program.sectMap["platform_lib"] = "DDR3";
[Question2] How to use platform_write() function??? (platform library)
There are the following error phenomena: Please give me some advice.
>>> error status ... suspeded screen
I also saw red error messages and added a path to the platform.c file.(path info ... C:\ti\pdk_C6678_1_1_2_6\packages\ti\platform\evmc6678l\platform_lib\src)
platform_write_configure() function ... PLATFORM_WRITE_PRINTF option is good.
PLATFORM_WRITE_UART option is wrong!@~
//****************************************************************************************************************
Is this an error in platform_lib?
There seems to be no problem with the source of the platform.c file.
The PLATFORM_WRITE_PRINTF option confirms that it works well, but the above error persists with the PLATFORM_WRITE_UART option.
After testing platform_lib, there is an error:
The write_type was confirmed to be PLATFORM_WRITE_UART but did not enter the block.
if ((write_type == PLATFORM_WRITE_UART) || (write_type == PLATFORM_WRITE_ALL)) {
....
printf( "\n -UART");//################################
...
}
It's strange!~~
Please advice on what to do. For debugging.

Test result is my mistake that not called platform_init() ... @@
