LAUNCHXL2-570LC43: Configuring GCM on HALCOGEN to have an external output clock of 24MHz.

Hi Alejandro,

Mainly we can output two clocks on ECLK1(External Clock out pin).

Either VLCK1 or Oscillator clocks can be directly given to the ELCK pin.

But this VLCK1 can again be any of the clock domains, like as shown below:

So, as you can see the VLCK1 can be derived from OSC, PLL1, PLL2, LPO LOW, LPO HIGH and External etc.

So, these are all the possibilities of the clocks that we can route to the external clock pin.

And i created one example project here to output a 15Mhz clock to the ECLK1 pin as shown below

ECLK1_TEST_LC4357.zip

And after executing this project i can see the output of 15Mhz clock on the A12 pin of the TMS570LC4357 controller

Thanks Jagadish for your quick and well explained response. 
I'll check out the provided project and test the same settings on my own. 

Besides changing the configuration on the ECLK window, do I need to make sure that the any other configuration for the A12 is in place?
Not sure if I need to make sure PINMUX configuration is properly selecting the pin's functionality for external clock. I think that might not be the case given that the SYSPC1 register handles that. 

The only changes after adding the configuration on the ECLK window are on the HL_System.c, HL_System.h and .dil file
I'm not seeing any output on the A12 pin.

This is the current configuration of the project that I'm working with
