TMS320F28379D: Problem with setting clock speed to 200 MHz

Hi Justin,

I followed this post in order to set my clock speed to 200 MHz (else it is 100 MHz for some reason)

I dont see any post link attached here. Can you explain what your clock configs are ?

Did your code compile before adding the clock configs ?

But, somehow I keep getting the following errors:

"C:/ti/c2000/C2000Ware_5_02_00_00/driverlib/f2837xd/driverlib/adc.h", line 175: error #41: expected an identifier
"C:/ti/c2000/C2000Ware_5_02_00_00/driverlib/f2837xd/driverlib/adc.h", line 176: error #41: expected an identifier

Thanks

Hi Prarthan,

Thanks for the reply! The post I followed is: https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1211129/launchxl-f28379d-how-to-set-up-the-system-clock-to-200mhz---3

I don't know what you mean by my clock config (I am new to TI MCU), but I want to add this SysCtl_setClock(DEVICE_SETCLOCK_CFG); to make my clock 200 MHz. For this line to work, I needed to include device.h and driverlib.h, and then the driverlib.h gives the error I have indicated. My code will compile without including device.h and driverlib.h.

I look forward to your reply.

Hi Justin,

That's strange. Can you re-import the project in CCS and see if it complies ?
Are you using latest CCS and C2000Ware ? If not please try with the latest version.

I would also advise to import any current examples from the c2000ware to see if that works for you.

Thanks

Hi Prarthan,

Sorry for the late reply. I tried your suggestions and found that: examples from driverlib folder of c2000ware can compile with device.h and driverlib.h, but examples from the device_support folder canNOT compile. Is there a reason for this?

With this in mind, what are the differences between driverlib and device_support folder examples and which one do you recommend me to use?

Thanks
