iMX28 pins are shared between several functions. The "ball map" only shows primary function.

For example, primary UART3 RX / TX pins are M5 and L5. Those pins are are NC with iMX286, but pin B3 and C4 (primary functions are SSP2_MISO and SSP2_SSO) can be configured to UART3 RX and TX.

Download "i.MX28 Applications Processor Reference Manual(MCIMX28RM.pdf)" and refer to Chapter 8 and 9 for more description.

Thank you. I got the document and I´m checking chapters 8 and 9.
