Nios II appears to have an issue with the 'stbio' instruction. When executing this code: 0x00400848 <+136>: stbio r3,0(r2) With these registers: r2 0x44000c 4456460 r3 0x3 3 The memory location (which is a memory-mapped register in the NS16550 IP block) ends up with the value 0x103 instead of 0x3 as expected. Before the instruction ran, the register had 0 in it. 32-bit version doesn't seem to have this problem, use that everywhere for now. This issue has been reported to Altera.
