Hi there to everyone.
I have a ADuC7126 Evaluation Board, uvision3, Realview-compiler and want to evaluate a Signal Generator.
As i found the 41.7792 MHz PLL has a strong jitter, i thought it would be a good idea to supply the ADuC7126 with an external 40MHz XTAL-Clock on P0.7
So i found i had locked myself out, it is not possible to Download Flash anymore.
Probably my code was to stupid, i need an example-code how to switch to external clock source.
The code in the datasheet is not complete.
Everytime i want to download Flash or entering the debugger the error-message appears "Cannot stop Arm device"
Can this be repaired without replacing the ADuC7126 with a soldering iron?
