Hi Wesley, Danny, It don't think its was a power issue as the RPi 3b+ was getting its power from the 40 pin connection to the SNAP board. I measured the current draw to be around 1.1A at idle when using a RPi 3b and around 1.8A when running firmware. These measurements were made by connecting a multimeter between a power supply and the 12v input of the SNAP board. It's more of a total current draw and not the current draw of RPi since I didn't want to hack up a connector. The issue looks like an incompatible image. So, after writing Danny's image with the dd command and some failed boot's (kept getting an error of something like kernel panic but it happened so fast I didn't get to read the whole message before it shutdowns), I wrote the image on a semi-fresh SD card with etcher and booted, install casperfpga and the SNAP board programmed successfully. It would be nice to get an official image.
Also, out of curiosity. What is tcpborphserver? thanks, Nivek On 29/08/2018 12:35, Danny Price wrote: Hi Nivek, I had the same issue, I think the image is not compatible with RPi3. I worked around this, and got tcpborphserver running on the stock RPi3 image, try this: https://drive.google.com/open?id=19ZSioiAVmYqa1w6SHvdIwo47Wi4wGefI Let me know if this works for you too; in which case might be worth making a more official release. Cheers, Danny PS: I burned this using etcher, which is a neat UI tool (https://etcher.io/) On 29 August 2018 at 8:28:51 pm, Wesley New (wes...@ska.ac.za<mailto:wes...@ska.ac.za>) wrote: Hi Nivek, I would take a read through this https://raspberrypi.stackexchange.com/questions/19354/raspberry-pi-with-boots-up-with-rainbow-screen Also confirm that you have a power supply that can deliver 2.5A at 5v. I have not used that image before, but you can plug the card into your PC and check if it mounts correctly and the boot partition is there.

I've download the image from the SNAP bringup tutorial and tried to get it to boot but it fails (the raspberry pi basically just outputs a rainbow pattern on the monitor with the red power led on and stays there). I'm guessing it fails because the image was not compiled to run on this new raspberry pi. Is it possible to get the raspberry pi 3 b+ working with the SNAP board? thanks, Nivek Ghazi -- You received this message because you are subscribed to the Google Groups "casper@lists.berkeley.edu<mailto:casper@lists.berkeley.edu>" group.
