Hi, Mark,
Yeah packet sockets do require extra privileges. The solution/workaround that
Hashpipe uses is to instal hashpipe with the suid bit set. The init()
functions of the threads will be called with the privileges of the suid user.
Then hashpipe will drop the suid privileges before
Hi all,
Hope you're doing fine. I was able to add packet sockets and the functions
provided by Hashpipe in hashpipe_pktsock.h, but I get permission issues
when trying to capture packets as a non-root user.
The method I am trying to use to overcome this is owning the
plugins/executables as root
Yes, the error comes from the Vivado compilation stage..
Today I changed the hls code to not use the hls_stream objects in the
input/output ports and I have been able to compile the model, so the
problem seems to be in that direction.
I think I need more time reading the hls_stream documentation
Thanks Adam
I am not building a custom FPGA board. I will be using the Red Pitaya and
ZCU 111 to build custom projects and applications I can do with these
boards. I am sorry if I didn't make that clear.
I was just checking how to proceed further since I got all the tutorials to
work and have a
Hi Aravind,
I am assuming you are referring to custom boards other than the Red Pitaya
and that you are using the Red Pitaya as a learning platform?
If so our annual Hardware Porting Workshop is a great way to learn how to
port to custom hardware - alas, that has been postponed this year.
In
Thank you Adam, I will send the email out to learn more about the ZCU111
work going on. I did join the Slack channel. I will check that out as well.
What would be a good way to build on these red pitaya tutorials to develop
custom applications?

Ramesh,
I've never actually gotten a ROACH to talk directly to a server. The
auto-negotiation in the NIC is not great.
You pretty much need a switch in-between. Which is why Jason recommended
using an old 100Mbps switch.
Regards,
James

Yeah, but as I say, this never fixed the 1Gbps problem anyway. Was a weird
problem.

I just tried this by putting a spare network interface on to 100mbps and also
forcing the ROACH1 eth0 to 100mpbs - this did not help. Looks like the ethernet
device on the ROACH1 is dead.
I used mii-tool to force 100mbps operation:
root@roach:~# mii-tool -F 100baseTx-HD eth0
root@roach:~#
Dear Ramesh,
Here is the link you can download and write the image to the SD card. If
possible use the 2GB SD card which is shipped along with the board.
https://drive.google.com/open?id=1sK69IUDKkdEw3W6aF0r7wll0QR1KoSiS
sudo dd of=/dev/mmcblk0p1 if=~/roach1_imagebkup_20190416_2GB.img
Note
Hi Indrajit,
Useful to know - I believe I do have our original ROACH1 image somewhere,
therefore I will try what you suggested.
Thanks!
Cheers,
Ramesh

Just to add to what Jason has said, older 100 Mbps switches are easy enough
to pick up secondhand on eBay and such, depending on where you are. They're
quite cheap.

Hi Sebastian,
What you're suggesting _should_ work, but I don't know of anyone that has
actually tried. Before getting too deep, does your design compile without
the HLS black box in simulink?
Does your error come from system generator or from the backend vivado
compile? If the latter, you can
Dear Ramesh Karuppusamy,
This kind of issues we faced several times, We use to do re-write the SD
card image. Then it gets resolved. If you want the image for the roach1
I can provide the same. Then you can copy your BOF and run your code.

Thanks and Regards

This actually wouldn't work anyway (we tried it). Something is broken in that

Thanks Jason, I thought about it.
Since we are running the ancient Debian Etch on this unit, I have no access to
ethtool, with which I understand that you can switch to 100mpbs. Is there any
other way to force 100mbps operation?

Can you try it with a 100mbps link partner? ROACH1's PHY was notoriously fickle
at 1Gbps. We never did get to the bottom of it, even with Nat.Semi's support,
and switched PHYs on ROACH2.

Dear All,
I hope you are all staying healthy.
The gigabit ethernet on our ~10 year old ROACH1 board went silent all of a
sudden this morning. The ethernet port show no activity (the yellow LED
flickers very occasionally). On booting the unit off the SD card, and manually
