10. UCB1400 Generates Interrupts Incorrectly
Problem: The Philips UCB1400 interrupt signal is inverted.
Implication: The UCB1400 generates interrupts incorrectly.
Workaround: Reprogram FPGA U53/U54 with latest code. Refer to http://developer.intel.com for latest FPGA
updates.
Status: Fixed
Board Rev: Rev A and B
11. USB Cable Attach/Detach Detection Interrupt Is Constantly Asserted
Problem: Due to the hardware implementation of the USB cable detection feature, either the attach or detach
interrupt is constantly asserted depending on the attach or detach state of the cable.
Implication: Software does not know if there is a connect or disconnect. Incorrect USB state can be read
Workaround: Perform the following steps to fix the problem.
1. Replace U12, MAX6348XR40 with MAX6379XR44.
2. Update U53/U54 with the latest code. Refer to http://developer.intel.com for latest FPGA
updates.
One bit was added in the Miscellaneous Read register, bit 9, for cable detection state. Bit 9: logic
low = attach, logic high = detach. There are now two interrupt register bits both in the Interrupt
Mask/Enable and Interrupt Set/Clear registers to handle USB cable attach/detach states. Bit 2 is the
interrupt bit for attach and bit 6 is the interrup t bit f or detach in both registers. Users must use each
register’s associated mask-bit accordingly. That is, users cannot clear the attach interrupt register if
the USB cable is attached. Users must determine the state of the cable attach using bit 9 in the
Miscellaneous Read register and then mask the associated in terru pt bit in the Interrupt Mask/
Enable register. Refer to the Intel
Personal Internet Client Architecture User’s Guide for more information.

12. 100-MHz SDRAM Failure
Problem: Excessive ringing on SDCLK pin.
Implication: SDRAM does not run at 100MHz.
Workaround: For 100-MHz SDRAM development, Intel recommends using Rev F of the DCPXA250 processor
card in addition to this workaround. Contact your local Intel representative for availability.
Add a resistor termination network at the end of the SDCLK1 clock line.
1. Locate C68 on the top of the BBPXA2xx development baseboard. Solder one end of a
100-ohm, 0805 resistor to the plus (+) side of C68. Point this 100-ohm, 0805 resistor straight
up.
2. Solder one end of a 470-ohm, 0805 resistor to the ground side of C68. Point the 470-ohm,
0805 resistor straight up.
3. Connect the open sides of both the 100-ohm and 470-ohm resistors together with a small
gauge rework-wire.
4. Connect this junction to U40, pin 44.
Status: No Fix
Board Rev: Rev A and B
14. LCD Touch Screen Intermittently Fails
Problem: LCD screen is open to excessive noise disruption on the touch screen.
Implication: Excessive noise disruption reduces LCD screen display quality. The touch screen may not work
correctly.
Note: BBPXA2xx development baseboards received after December 2001 do not require this ECO. The
manufacturing process was changed to incorporate this ECO.
Workaround: Fix this problem by covering the back light inverter with copper foil shielding tape to decrease the
electrical noise transferred to the LCD and Touch Screen.
Material Needed:
• 1-inch heat shrink tubing.
• 2-inch wide EMI Copper Foil Shielding Tape.
Procedure:
1. Disassemble the BBPXA2xx development baseboard touch screen enclosure.
2. Remove the back light inverter.
3. Cut a piece of heat shrink tubing (1”x3”) and place over the inverter.
4. Heat the tubing until it collapses on the inverter.
5. Cut a 2”x5” piece of copper tape and place on clear plastic disk covering the inverter. The
adhesive side should face the plastic.
6. Cut a 2”x5” piece of copper tape and place on the black plastic disk under the inverter. The
adhesive side should face the back of the LCD metal enclosure.
7. Reassemble the touch screen enclosure.

Problem: There is a new revision of the Philips UCB1400 audio code c. BBPXA2xx development baseboards
are now using UCB1400 Rev 2A (CB0829). The previous revision of the UCB1400 is
(CA5878).
There are software changes that are required to support the new revision of the
Rev 1B
UCB1400.
Implication: Current production versions of BBPXA2xx development baseboards use the new revision of the
UCB1400.
Workaround: Versions of Windows CE and Diagnostic Manager released after April 1st, 2002 automatically
detect the revision of the UCB1400 and configure it accordingly. Users writing their own software
for the UCB1400 should refer to the latest Philips UCB1400 document ation to ensure they are
configuring the new revision appropriately.
Status: Fixed
Board Rev: Rev B
16. Conditional ECO To Use 3.3-V PCMCIA Cards
Problem: The BBPXA2xx development baseboard does not support 3.3-V PCMCIA cards because it has a
5-V PCMCIA slot.
Implication: 3.3-V PCMCIA cards cannot be inserted into the 5-V slot.
Workaround: Replace 5-V PC-card header connector (part #535651-1) on the BBPXA2xx I/O board with 3.3-V
PC-card header connector (part #535651-2).
Status: No Fix
Board Rev: Rev A and B
17. Conditional ECO To Use The Expansion Port J26
Problem: The BBPXA2xx development baseboard does not support interfacing to the expansion port J26.
The X-RDY signal is tied low via R76B. This renders the port inactive.
Implication: Users of the BBPXA2xx development baseboard cannot use the expansion bus for development.
Workaround: Remove R76B and update U46 with the latest CPLD code. Refer to http://developer.intel.com for
latest CPLD updates.
Status: No Fix

Problem: On systems using an oscillator to drive PEXTAL, the 3.3 V output from the oscillator is too high.
Implication: Possible damage to chip.
Workaround: Follow the steps below:
Note: These steps bring the oscillator voltage down to 1.1 V. The oscillator and core voltages need to be
equal.
1. Attach one side of a 430-ohm resistor to the bottom (on the bottom of the processor card) of
TP19 (ground).
2. Attach a 30-AWG wire from the remainin g side of the 430-oh m to crystal X1 (The pin clos est
to the edge of the board).
3. Attach one side of a 620-ohm resistor to the junction of the wire and the 430-ohm resistor. The
