I thought I should start a new topic instead of replying to member's post to get attention.

 

I am having problem with my PK60F120M (mask code 1N96B) chips. They are oscillating at 1.45 KHz (sawtooth wave swings from 0 V to 1.6V). I tried all suggestions given by other members, such as holding the reset pin while powering up, reduce the power up slew rate, pull the EZ_CS pin high, etc without success.

 

I have sent direct request to Freescale technical support with no answer after 48 hours. The FAE can't give positive suggestion too. We are basically left in the dark.

 

I need the solution urgently, please can someone help.

 

Thanks.
