Logicloader hangs on 'go ff480000'

peddamat — Fri, 12 May 2006 09:16:23 GMT

Oops, just found a problem. I'm trying to load the Logicloader from flash, and executing the command 'go ff480000' just hangs the MCU. Pressing the interrupt key doesn't break the loop. Any idea what's going on?

Thanks,

Sumanth Peddamatham

Hi Sumanth,

A company called LogicPD built the board for Freescale but also added some of their own software to the kits.

Best to contact them (http://www.logicpd.com/support/) with this question as they are the experts with the LogicLoader.

Regards, DavidS

LoLo should be at ff840000 by default, not ff480000.

Try typing 'go ff840000' and see if that makes any difference.

I appreciate both of your replies. I made a typo, in my initial post. The loader also hangs when I type 'go ff840000'. I'm going to try reloading the firmware with the BDM device once I have a chance. If that doesn't work, I'll contact logicpd. I'll let you know of any updates.

Thanks again,

Doing some cursory debugging... When I display the memory at 'ff840000', I get the following:

dBUG> md ff840000

Looks to me like the loader isn't at that offset, am I correct?

Thanks,
