I'm trying to use multiple snapshot blocks with an external trigger so that I
can capture multiple streams simultaneously. I built a small subsystem (see
attached image) with four data inputs, one trig input, and four snapshot blocks
(with none of their optional features enabled). My hope was

Thanks for looking into this.

Interesting. I just did some sims and also can't replicate this behavior in

Hi Dave

Jason also had a problem with snapshot blocks using ROACH2. His snap
block would not finish capturing, i.e write 7 into the control register,
busy bit goes high and byte count spins, but busy bit never goes low
again! Again, the logic to finish capturing is very
Hi Dave
I think Andrews point 3 is relevant.
We have picked up on transient on the register write with the latest memory
mapped TCPBORPH. It seems that sometimes, some of the bits goes high for a
short while and then settles at the required register value.

Hi,
I seem to be running into this same problem. Will tcpborphserver2 run
on the same linux kernel or do I need to change to a borph specific
kernel?
Thanks,

Hi all,
FWIW, I use these snapshots extensively on ROACH2 and have not had any
issues. However I'm still compiling using 11.x and still running
tcpborphserver2.
Best,

So tcpborphserver2 requires a borph kernel, the kind where you can
run a .bof file like an

Hi, Marc,
I can confirm that the wordwrite workaround works. Hopefully the fix for byte
enables (either to make tcpborphserver3 not use them or to make the gateware
support them) will not be too hard.
Thanks,

Dave if the wordwrite workaround works lets stick to that for now. The
workaround Marc compiled is not really good for release. We'll work on a
proper release but for now use wordwrite if thats ok?

So far, the wordwrite workaround does not appear to be working for me, but
I'm still investigating.

Hi, Alec,
This is a serious bug. Even though the workaround seems to work (still pending
Glenn's testing), having to worry about when to use ?wordwrite vs ?write is
very unfriendly for users/programmers. It would be good to fix it sooner
rather than later, IMHO.

Jup, Marc is working on this, he has already fixed it but the corner cases
are tricky and needs a bit of attention before it is ready for release.
