There is no document or change list showing the difference between m8/b and gxl/axg serial chips. Now it seems that we can't use command NFC_CMD_N2M on nand initialization for m8/b chips and use *read byte from NFC fifo register* instead. > > Martin > > . > _______________________________________________ linux-amlogic mailing list linux-amlogic@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-amlogic
