ok, I'm confused. So this isn't an uart inside CPS hardware, but an uart used by CPS code for debug output, right ? To solve the issued please add CONFIG_MIPS_CPS_NS16550_WIDTH to select the correct access width. Thomas. -- Crap can work. Given enough thrust pigs will fly, but it's not necessarily a good idea.
