Peter,
Thanks for verifying this in your environment.
When you say communications issue do you mean something other than
electrical noise?
I doubt that there is a noise issue with my communications as right now I
am in a pretty
good environment. There are no drives or other noisy devices running, the
mesa hardware is mounted to a 3/8" thick grounded
aluminum sub panel with standoffs. The 5v power supply is ungrounded but
supplied through a shielded cable with the shield
single point grounded to the subpanel. The power looks clean on a scope.
The subpanel is connected to the PE (protective earth)
for the building. The ethernet CAT5E UTP cable is maybe about 3' long.
If I read the FPGA hmid using mesaflash I also read 65535. If the data was
bad from noise then wouldn't
the packet be dropped (bad crc) and other data besides the idrom value be
incorrect?
but the mesaflash --readhmid returns all of the other info that is expected
- i think.
the output looks like this:

Now if I load a different .bit file like 7i80hd_25_svsp8_6_7i46 then I get
back the idrom value of 3 which is expected.
So now I wonder if for your test you used the bit file downloaded from the
mesa website in the 7i80 zip file or did you
use a file from some other place?
regards,
John Figie
