Santiago Posted April 12, 2021 Share Posted April 12, 2021 Hi everyone. My name is Santiago. I am assistant in my electronics class. We have a problem with 5 of the coolrunner-ii that are in our laboratory. When we conect them to the pc it is just turned on LD4, but LD6 and LD5 are turned off. Could you give us a reccomendation to fix it?. Could you show us a troubleshooting for CPLD coolrunner-ii to try to repair them?. Thank you. It wil be really useful.

JColvin Posted April 12, 2021 Share Posted April 12, 2021 Hi @Santiago, The Coolrunner-ii is a retired product, so the available support for it is very limited outside of what is available on it's Resource Center: https://reference.digilentinc.com/reference/programmable-logic/coolrunner-ii/start. My brief advice after looking at the schematic and reference manual would be to check JP2 and checking a different USB cable since the Link and Power LEDs aren't turning on. Thanks, JColvin Link to comment Share on other sites More sharing options...
