4.3.1 Default Jumper Positions

The figure below illustrates the default jumper positions as mounted when the board is delivered from

Embedded Artists.

Note that the “Enable JTAG” jumper shall NOT be inserted. The enable state is different for the

LPC3250 than on the LPC2478 (which the QVGA Base Board was originally designed for).

4.3.2 Illegal Jumper Combinations

Note that some jumpers are mutual exclusive and should not be inserted simultaneously.

 USB-OTG and LCD interface; the four jumpers in J25 should not be inserted when using the

LCD interface since signals (P1.27-P1.29) are also connected to the ISP1301.
