Hi,
I am using the 6678 evm board (shannon board), and was running the platform test example.
Actually I am trying to get some output on UART terminal. Switch configuration is:
| (off, off, on, off)1,2 | (on, on, on, on)3 | (on, on, on, off)4 | (on, on, on, on) |
In UART, I got some problems initially like no return from function platform_init() function, so I use gel file evmc6678l.c to initialize pll and ddr. My gel out put is showing one error as highlighted "L1P error detection logic enable is failed".
Following is the required information:
1. Path of GEL file:
C:\Texas Instruments\ccsv5\ccs_base_5.0.3.00028\emulation\boards\evmc6678l\gel
Following changes were done in default gel file:
//Changes made in gel file
StartUp( )
{
i2cprog=0;
Setup_Memory_Map( );
OnTargetConnect(); <====== Added ======
}
=========
2. Output of GEL file execution:

3. Sample code:
void main (int argc, char *argv[])
{
platform_init_flags init_flags;
platform_init_config init_config;
platform_info p_info;
uint32_t led_no=0;
char message[]="Hello World\n";
uint32_t length=strlen((char *)message);
uint32_t i;
/* Set default values */
memset(&init_flags, 0x01, sizeof(platform_init_flags));
memset(&init_config, 0x0, sizeof(platform_init_config)); // Changed: 20120709
init_flags.pll=0;
init_flags.ddr=0;
memset(&init_flags, 0x00, sizeof(platform_init_flags));
printf("Platform is running part 1 \n");
if (platform_init(&init_flags, &init_config) != Platform_EOK) {
printf("Platform failed to initialize, errno = 0x%x \n", platform_errno);
return;
}
printf("Platform is running part 2 \n");
// platform_write_configure(PLATFORM_WRITE_PRINTF);
platform_write_configure(PLATFORM_WRITE_UART);
if(platform_uart_init()!= Platform_EOK);
printf("Platform is running part 2 Failed\n");
printf("Platform is running part 3 \n");
if(platform_uart_set_baudrate(115200)!= Platform_EOK)
printf("Platform is running part 3 Failed\n");
printf("Platform is running part 4\n");
//platform_get_info(&p_info);
for(i=0;i<length;i++)
{
printf("Platform is running part 5 [%d]\n",i);
if(platform_uart_write(message[i])!= Platform_EOK)
{
printf("platform_uart_write failed, errno = 0x%x \n", platform_errno);
//return;
}
}
printf("Platform is running part 6 \n");
}
=========
4. Program output on CCS console after running using CCS:
[TMS320C66x_0] Platform is running part 1
[TMS320C66x_0] Platform is running part 2
[TMS320C66x_0] Platform is running part 3
[TMS320C66x_0] Platform is running part 4
[TMS320C66x_0] Platform is running part 5 [0]
==================================================
It seems that platform_uart_write() is not returning back. Hanged or stuck in forever looping.
Can anyone suggest what can be the issue.
Thanks
