Hi
anyone has made it own microblaze soc (eg not using ML401 derivate) where PLB is connected to microblaze OPB over bridge and some peripherals live on the PLB bus? I am struggling with this and can find the problem, for testing I just connected PLB GPIO, it seems to be kind of visible over OPB2PLB bridge, but there is defenetly any writes working :(
This can be done and is used in ML401 ref design, but there seem to be some 'special gotchas' that one has to know to make it work, so if anyone had some problem with similar design and has some hints I would be extremly thankful
