motorola mv5500 VME A32 writes

Hello All,

Does anybody have experience writing to A32 address space on a
Motorola mvme-5500 board with vxworks 6.3. Mine can read and write
A16 fine, and reads A32 ok, but when writes to A32 are tried in "real
time" chaos results, i.e., the logic analyzer see missing write
addresses and gives indication that the address is not found on the
bus. I can get the writes to work with an artificial delay between
individual writes.

The exact same code works fine all around on a Motorola mvme-5107 and
vxworks 5.5.

Any ideas?

Thanks,

Doug
