When i connect SAM ICE to Board designed by Us.
It used to give error while connecting :
Unable to halt ARM core:
a) No CPU clock
b) nWait signal active
c) ICEBreaker disabled(DBGEN:...Jumper Setting)
kindly find the comments for the above problems A)I connected 18.432 MHz crystal(abracon) with 22 pF CLoad.
I found out the crystal clock is not coming always...
when i do few power cycles ON/OFF clock started appearing.
In that secenario I m able to enter into debug mode but after runnig it Again shows the same error :Unale to Halt Arm core.
and clock also disappears.
But on the AT91SAM7x256 eval board clock always comes and debugger works fine.
Kindly comment on this.
B) I searched in the Datasheet there is no nWait signal for AT91SAM7x256.
C) No idea what it is.
Kindly help me on this and send ur comment ASAP.
