Hi thosburke,

When you choose altera 1c12 board, the microtronix mtd map is selected. It is located in kernel source drivers/mtd/maps/microtronix.c, and right now the romfs is allocated 6M, as follows, 

static struct mtd_partition microtronix_partitions = {
    {
  .name =  "romfs",
  .size =  0x600000,
  .offset =    0x200000,
    },{
  .name =  "loader/kernel",
  .size =  0x200000,
  .offset =    0,
    }
};

I don't know if you have changed the size of romfs partition. Since you have 16M flash, you can increase that size and have a try.

At the same time, I am tring to get the old romfs map to work, and will post that shortly.
