Problem due to PLL multiplication factor. - Arun Karuppaswamy B - May 14 8:37:57 2007



Hi all,
      Thanks for the replies I got for my query regarding the loading problem. Actually, the
problem was not due to the cmd file or due to the flashing (I have not flashed the code at
all). I found out that the error is due to the PLL factor. Except for PLL factors 10 and 9,
i.e. 150 MHz and 135 MHz (with a 30 MHz external crystal), all other PLL factors give wrong
result (and I was using PLL factor as 5). Has anyone experienced the same problem before?
'cause otherwise I need to check my board for any other errors. And, as per TI data sheet there
is a known error that some PLL factors automatically reenable the Watchdog timer.
   
  Regards,
   akp.
