13 years agoD19 Error LED illuminates when DE4 board is power on
Hi,
I have encountered a problem with Altera DE4 board EP4SGX530KH40C2. When I turn on the power, D18 Load LED illuminates, but shortly it goes out. Then D19 Error LCD illuminates. User LEDs do not flash in sequential pattern. 7-segment display do not light up or show IP address. It seems that the board does not start-up correctly. From the document DE4 User Manual, I see the following message: D19 Error : Illuminates when the MAX II CPLD EPM2210 System Controller fails to configure the FPGA. Driven by the MAX II CPLD EPM2210 System Controller. I guess the problem is that EPM2210 System Controller fails to load preloaded default configuration bit streams onto the CFI flash memory. Can you help me with the problem? Thank you very much for your help. Wenju
