Normally the BE case gets handled automagically (moreover, there is MIPS option that additionally controls I/O and memory space byte swapping). The case we have to address for TX493x is actually where the usual magic fails (or actually the code just doesn't want to use that option). So this doesn't look like a good name to me... > Thanks, > Bart WBR, Sergei
