Intel® DCPXA210 Processor Card

Intel® DCPXA210 Processor Card

1.	For Multi-ICE JTAG Use
Problem:	JTAG connection fails when using ARM Multi-ICE tools.
Implication:	No JTAG debugging facility available with ARM Multi-ICE.
Workaround:	Use the following steps to
	1.	Cut a trace on the front of the board between U1 pin 3 and via to the right.
	2.	Add 30-AWG wire from J2-3, to the bottom via of U1 pin1.
Note:	Step 3 is not required for the Rev A DCPXA210 processor cards and ARM Multi-ICE with their
	own power supply.
	3.	Add 30-AWG wire from J2-2 to +3.3 V.
Note:	Perform this modification only if using the ARM Multi-ICE tool. This ECO does not affect the
	performance of other JTAG tools.
Status:	No Fix
Board Rev:	Rev A
2.	MMC MMCLK Support
Problem:	DCPXA210 processor card does not allow simultaneous support of FFUART and MultiMedia
	Cards (MMC).
Implication:	This limits peripheral support to either the FFUART or the MMC.
Workaround:	Follow the steps below to fix the problem:
	1.	Remove 0-ohm resistor R17.
	2.	Add 30-AWG wire from R17 pad (PXA210 pin N14 side) to S5 pin 2.
Status:	No Fix
Board Rev:	Rev A
3.	PLL Voltage Too High
Problem:	The 3.3V PEXTAL output from the oscillator is too high.
Implication:	The too high output could cause damage to the PXA250 applications processor.
Workaround:	The voltage divider lowers the voltage from 3.3 V to approximately 1.1 V.
	1.	Remove the 0-ohm resistor, R54B, and replace it with a 1-kohm resistor.
	2.	Attach one side of a 470-ohm resistor to R54B side X1 pin 2 (PEXTAL signal).
	3.	Run a new wire from the open side of the 470-ohm resistor to GND.
Status:	No Fix
Board Rev:	Rev A
