TechnoFolle Posted April 21, 2017 Share Posted April 21, 2017 Hi guys, I'm trying to use Reveal in my project but the Reveal Analyzer shows me this error: ERROR: core0 cannot trigger. See Reveal Troubleshooting Guide for more details. Problem cause is sample clock or power off. I don't understand the error message, the board is correctly power on and the clock is working since I use it to turn on/off some leds. Someone can help me? Thanks in advance!

D@n Posted April 21, 2017 Share Posted April 21, 2017 You can find the Reveal User's Guide here, as well as the Reveal Troubleshooting Guide here. I'm personally not all that familiar with Reveal. I've used an open source analyzer for my own work (I call it a "wishbone scope", but an AXI implementation exists). This type of scope implementation, though, depends upon having a "bus" within your design (I use wishbone) in order to do anything useful.

TechnoFolle Posted April 26, 2017 Author Share Posted April 26, 2017 Hi Dan, thanks for the answer. I read both Guide but nothing helpfull inside in this case. The open source analyzer is great, but I have no buses, only custom logic in the design, so I need to use the Reveal Analyzer. Luca Link to comment Share on other sites More sharing options...

Ok ... is it your custom logic, or someone else's custom logic that you are struggling to understand? On the same notes, do you have the source for this custom logic? Can you edit the logic at all?

TechnoFolle Posted April 27, 2017 Author Share Posted April 27, 2017 Hi @D@n, it's my logic and I have the source code. Just for information the specific problem with the Reveal is due to usb cable. For some reason the cable given with the demo board doesn't work. On 21/4/2017 at 4:21 PM, TechnoFolle said: ERROR: core0 cannot trigger. See Reveal Troubleshooting Guide for more details. Problem cause is sample clock or power off. Changing the cable the Reveal analyzer start working in the right way. Thanks Luca Link to comment Share on other sites More sharing options...
D@n Posted April 27, 2017 Share Posted April 27, 2017 @TechnoFolle, Glad you got it working! The bad USB cable is sadly a common occurrence. I haven't run the numbers, but ... I think I've seen more hardware failures due to bad USB cables than any other component breaking. Dan Link to comment Share on other sites More sharing options...

Hi guys,
I'm trying to use Reveal in my project but the Reveal Analyzer shows me this error:
ERROR: core0 cannot trigger. See Reveal Troubleshooting Guide for more details.
Problem cause is sample clock or power off.
I don't understand the error message, the board is correctly power on and the clock is working since I use it to turn on/off some leds.
Someone can help me?
Thanks in advance!
