Hi Jeff, Thanks for the suggestion. I checked the /etc/hosts file on my RPi and the “127.0.0.1 localhost” line is already there.

Odd? Hi, I had same error “no programming informs yet. Odd?” with Red Pitaya. Solution there was to ssh into Red Pitaya and add the following line to etc/hosts file: 127.0.0.1 localhost I’m not familiar with SNAP though. Good luck! -- Jeff From: Jack Hickish <jackhick...@gmail.com> Sent: Thursday, July 22, 2021 8:32 AM To: casper <casper@lists.berkeley.edu> Cc: Tristan Ménard <tristan.men...@mail.mcgill.ca> Subject: Re: [casper] SNAP error: no programming informs yet. Odd? Hi Cynthia, Tristan, What model RPi are you using, and what type/length of ribbon cable is used to connect the Pi to the SNAP. Were both of these known-good hardware prior to installation in the case? Re. error recovery -- at the very least I would have thought restarting borphserver (probably `/etc/init.d/tcpborphserver3 restart` should work) if the error doesn't completely lock up the Pi forever.

In addition to the information in Tristan's email, I'll also add that fully power cycling the SNAP+RPi is the only way that we've found to clear the error, but even that doesn't work 100% of the time. Apart from helping us identify the root cause, does anyone know of a gentler way to clear the error without power cycling? thanks! Cynthia -------------------------- Hello, I am diagnosing a SNAP board error that has popped up while conducting field tests. We are using a 14-bit SNAP board along with a Raspberry Pi on a system that has successfully been used in the field before. The error message is as follows: “ERROR 127.0.0.1 transport_katcp.py:594 - 127.0.0.1<http://127.0.0.1>: no programming informs yet. Odd?”, which is repeatedly printed to the Raspberry Pi’s terminal screen. It occurs while initializing the SNAP board with casperfpga.upload_to_ram_and_program(). I’ve attached a picture of the error message for reference. The main difference between previous successful tests of this system and the current iteration is that the enclosure containing the SNAP board and the Raspberry Pi is placed inside a large pelican case that also houses our methanol fuel cell power unit. Some of the potential causes we’ve explored are overheating and RFI from the power unit. I’d greatly appreciate any input that folks on this mailing list might have regarding what might trigger this error.
