DCPXA250 Processor Card
7. For ARM* Multi-ICE* JTAG Use
Problem: JTAG connection fails when using ARM Multi-ICE tools.
Implication: No JTAG debugging facility is available with ARM Multi-ICE.
Workaround: Perform the following steps to fix the problem.
Note: This ECO does not affect the performance of other JTAG tools.
1. Cut the trace on the top of the processor card between U1 pin 3 and via to the right.
2. Add 30-AWG wire from the J3-3 to the via of U1 pin 1 on the bottom of the processor card.
Note: Step 3 is not required for the Rev C and Rev D DCPXA250 processor cards and ARM Multi-ICE
with their own power supply.
3. Add a 30-AWG wire from J3-2 to +3.3 V.
Status: Fixed
Board Rev: Rev C and D
