Hi Aditya,

Missing Clock Detect logic detects OSCCLK failure using INTOSC1 as reference clock source. When MCDCR bit is set, you can reset it by writing a "1" to MCLKCLR register. Writing a "1" to this bit will clear the MCLKSTS bit and reset the missing clock detect circuit.

You can also do a power restart to clear the bit.

Please have a look at the Missing Clock Detection Logic section in C28x system control and interrupt section in TRM for more information.

I will try to reproduce from my side and shall come back.

Please try to do a power restart of the board and try again if the issue persists. Also please let me know the device_setclock configuration in device.h file.

Thanks

Aswin

Hi Ashwin
I will try with the power restart.
For the device_setcloc config,  the definition is given below

It didn't work with power restart of board

Hi Aditya,

When you say it does not work, does it mean that it was still going to the ASSERT condition or it was going to the FAIL condition?

Can you update the DEVICE_SETCLOCK_CFG to use XTAL as the clock source and try the example again ( uncomment the #define USE_PLL_SRC_XTAL,
// and comment the #define USE_PLL_SRC_INTOSC.

Thanks

Aswin

it was still going to the ASSERT condition .

Currently is like this in device.h

Hi Aditya,

Can you attach the .out to this post?

I will try to run it from my side and let you know. Do you have an extra board to test, if yes please try it in another board.

 Can you confirm if the XTAL is connected or not? 

Also check the MCDCR register (write a 1 to MCLKCLR register would clear the MCLKSTS register)  and do a restart and try again.

Thanks

Aswin

PFA out file

dcc_ex2_single_shot_measurement.out

I tried clearing the MCLKSTS register, restart and try again.
But it didn't work.

Do I need to do anything else?

Thanks, Aswin for the info. I will try the suggested workflow.
