tms320f288335 crystal issue

gopu t

we have used 30mhz crystal, PLLCR value = 10 , DIVISION value = 2.we are facing problem flash reading. so we changed 30mhz to 15mhz crystal it is working ,but ti recommended only 20mhz to 35 mhz crystal?

hi Gopu,

Can you confirm that you are using the appropriate wait states for flash reads per table 6-70 in the datasheet?

If so have you verified the SYSCLK frequency using XCLKOUT or by toggling a GPIO?

Regards,

Joe

Gopu,

You may also want to check the crystal datasheet to see that it meets the other requirements that the F2833x puts on the crystal.

These requirements can be found in section 3.6.6.1 of the current datasheet.

Thank you,
Brett
