Dear Sir:

     We designed a circuit board based on MPC8308, because we don't use IRQ1 and IRQ3 of MPC8308, we leave the IRQ1# and IRQ3# pins of MPC8308 unconnected (we didn't connect pull-up resistors). Is this a serious problem? Will it make the MPC8308 abnormal ? Thanks!

     We had downloaded u-boot.bin into NOR flash on our board, but the u-boot can't boot. So we suspect if it relates to the unconnected IRQ pins of MPC8308.
