TMS320F28384D: USE_20MHZ_XTAL

Ajay S

Part Number: TMS320F28384D

Dear Team,

We have custom board with TMS320F28384D with external crystal 20MHZ.,

we have changed USE_20MHZ_XTAL in predefined symbol with respect to document control card and also already mentioned in device.c file.. in our project...

But in our project file, when we click (CTRL + DEVICE_SETCLOCK_CFG ) in device.c file..

its goes to 25MHZ_XTAL(else part in device.h)..... Cystal configuration not linking with ""USE_20MHZ_XTAL"" ...

//
// Set up PLL control and clock dividers
//
SysCtl_setClock(DEVICE_SETCLOCK_CFG);

we are using c2000 3.4 sdk version and latest CCS... please confirm how to USE_20MHZ_XTAL in our project....

thanks in advance.

Regards

Hi Ajay,

But you are observing the USE_20MHZ_XTAL section as active and the else section is grayed out, right?

Can you try a rebuild project and check again?

Note that the predefined symbols are specific to the build configurations. Are you checking with Flash build configuration?

Hi,

Can you please add the following in the main.c file and check the values of that variables. Just to check we are getting the correct values

uint32_t clockFreq = DEVICE_INTOSC_FREQ;

uint32_t config = DEVICE_SETCLOCK_CFG;
