Hi
Sorry my english
i am modify Fat Chan Example for LPC23xx to my LPC1778
if i am config DMA and MCI for recieve block №0, then i get only 480 bytes. But request 512 bytes. I am search lost 32 bytes in fifo MCI.

Why DMA controller do not read this bytes ?!

All images attach. Green color - bytes transfer ok to my mem, red - bytes transfer fail

DMA on LPC178x MCI is working, no problem.

Biggest Problem is the quality of the mci driver codes....

I am using the following MCI driver, which is working fine:

in one forum one programmer reported that he had received similar trouble on LPC2888 and in errata written "MCI.1 Rx FIFO is not functional"
may be this trouble migration to LPC1778 ?
