Which red LED are you referencing on the Arria 10 SOC dev kit? Perhaps you can provide more details of the issue that you are seeing. Have you try to set all the switches and jumper back according default factory settings? Please refer to the Arria 10 SoC Development Kit User Guide from the link below and check all the factory settings"
Thanks for your response.
I did talk to Brian Kang, the Intel rep. in the Los Angeles area and fixed the problems by reloading the manufacture FPGA image.
