Getting "Write memory failed: address 0x0" error message

[geochrist]

Hi there,

We are getting a

Write memory failed: address 0x0

Expected value:  0x1fffc420

Actual value:        0xffffffff

when trying to program a home made PCB that contains a MK40X512 device.  After this message, we get

[Chinese text] , A verify error has occurred while writing memory

We are using a PE Mimcrosystems USB Multilink Universal (RevA) (USB-ML-UNIVERSAL) programmer.

The programming succeeds when burning in the same program to a K40-KIT demo kit.  (This kit has 

a MK40X256 in it, though.)

Has anyone seen this before, or does anyone have any ideas what might be going on?

Thanks.

George

I remember the problem being a bad chip.  Needed a new one.

Are you sure? My chip is a BGA package and can´t quit and put!!

The K60 is new from arrow, and i have tested with 2 custom boards...

Thanks

Maybe your board is bad, then.  Sorry, but it was a while ago and I'm just repeating what my engineer told me.

Regards.

Can you tell me the mask of your ICs?

Thanks again.

I'm sorry but I don't have that information.  I am not working on that project anymore and no longer have access to the data.

Best wishes to you.
