PLATFORM_DEBUG = 1, platform_init(), debugging and print statements

Also,

       since this

#if (PLATFORM_DEBUG)
         #define IFPRINT(x) (x)
#else
          #define IFPRINT(x)
#endif

and there are many [around 51 inside platform.c] print statements like below,

IFPRINT(platform_write("PA PLL programmable divider = %d\n", ddr3_plld));

i expect it to work, let me know if my understanding is incorrect

wait. one more info..i am looking at uart for these prints. mm.in oneway..that may be incorrect as uart_init is yet to happen within this platform_init(). does this platform_write is to external world [uart to console]

====================

* @remark This routine will output the printf style string
* to one or both of the UART and/or through a printf
* call (in CCS this is mapped to the console window).
* By default, both are written. This can be controlled
* by setting write_type in the paltform_init structure.
* By default, both the UART and printf outputs are used.

void platform_write(const char *fmt, ...);

====================

Hi Ti folks,

                   you can close the post. I was able to resolve the issue

Here are my mistakes..which i was doing

1. I was always building PDK packages and after a while i checked in pdk build logs. nowhere it is touching platform_lib .ae66 .ae66e files.

2. in windows i imported the project C:\ti\pdk_C6678_1_0_0_21\packages\ti\platform\evmc6678l\platform_lib

and put the appropriate endian and compiler and rebuilt the project.this time it bulit the .ae66 [litle endian lib]

3.i closed the ccs

4. imported C:\ti\pdk_C6678_1_0_0_21\packages\ti\platform\evmc6678l\platform_test into ccs

5. while doing step 2, i put some prints inside the code and i can see them coming

6. a small correction is that i pull the following 3 lines before platform_init

platform_write_configure(PLATFORM_WRITE_PRINTF);
platform_uart_init();
platform_uart_set_baudrate(args.init_config_uart_baudrate);

if (platform_init(&init_flags, &init_config) != Platform_EOK) {
printf("Platform failed to initialize, errno = 0x%x \n", platform_errno);
}

this is to configure that print shud happen to OUTPUT CONSOLE not any uart.

7. i also enabled the debug prints PLATFORM_DEBUG = 1

8. i can see the prints as follows [boldened are my platform write statements]

C66xx_0] platform_uart_init called
[C66xx_0] platform_uart_set_baudrate(baudrate=115200) called
[C66xx_0] platform_uart_set_baudrate(baudrate=115200) called
[C66xx_0] Setup 1 Done.
[C66xx_0] Setup 2 Done.
[C66xx_0] SYSCLK/ALTCORECLK is the input to the PA PLL...
[C66xx_0] PA PLL programmable multiplier = 21
[C66xx_0] PA PLL programmable divider = 1
[C66xx_0] PLL3 Setup for PASSCLK @ 2580.5 MHz...
[C66xx_0] PLL3 Setup... Done.
[C66xx_0] PA PLL programmable multiplier = 20
[C66xx_0] PA PLL programmable divider = 1
[C66xx_0] PLL2 Setup... Done.

it took a while for me to understand which lib to build to get platform_lib working. but at the end it worked

Thanks
