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?
