hi,
i'm beging to write the 332xt driver.
i want to read/write to/from the 332xt memory from my mvme167 board
the board is not the scon. it is another 167.
i drop the not scon board in the sys debugger and type this:

167-Bug>md ff780000
FF780000  
Exception: Access Fault (Local Bus Timeout)
PC =FF84A7B8 SR =2704
Format/Vector =7008
SSW =0145 Fault Address =FF780000 Effective Address =FFE0D804 
167-Bug>

0xff780000 is supposed to be the base address of the 332xt board (configured
from the board jumpers)
but i think the the board can't decode the address and just access an adress of
the local memory space, not the vmebus one.

how can i, from the debuger of the mvme167, read or write (just for testing) in
the 332xt board ?
it is more a vme question than a netbsd question but i need this information to
read the statu register of the 332 board to know if it is working properly.

thanks.
