J1: Target reset configuration
Jumper J1 connects the reset line and the target reset line. By default, J1 is populated.
When having problems establishing the initial debug session with the Emulation Adapter (EA), try
to remove J1 and see if it makes any difference.
J2 and J3: Clock source configuration
Jumpers J2 and J3 select the clock source for the emulation device. The Emulation Adapter is
delivered with J2 and J3 set in the default position 1-2, closer to Pin 1 marking.
Position 1-2 (default) selects the crystal circuit oscillator on the target board. To select the crystal
circuit oscillator on the Emulation Adapter (Q1 socket), set:
1. Set both Jumpers J2 and J3 away from Pin 1 marking.
2. Insert the crystal circuit delivered with the Emulation Adapter into the Q1 socket.
The Emulation Adapter may not operate when the target board's crystal circuit is used
as the clock source. A typical design guideline is that the crystal should be as close as
possible to the SoC. The target crystal might not oscillate in conjunction with the
Emulation Adapter since the clock lines between the target crystal and the emulation
device on the Emulation Adapter become too long, thus affecting the impedance of the
crystal circuit.
The separately packed 20 MHz crystal* can be used as a 20 MHz external clock (XOSC)
source to the emulation device. If a different clock frequency is required, insert
appropriate crystal into the Q1 socket. Crystal socket Q1 is by default not populated
(NP).
* Emulation Adapters of revision A1 were delivered with a 40 MHz crystal.
