I have one Stratix 10 DX board and one USB Blaster II dongle for programming. Recently I want to try E-tile IP and want to bring up FPGA with 25G SFP port. So I prepare to use E tile transceiver toolkit for debug. Then I find every times I open sof file and want to download current configuration from FPGA. it will show operation timeout and can not finish my request command. I attach a picture for reference. I try to slow down JTAG clock. but it is useless. even 1MHz. So can anybody help to explain what is the error here. thanks .
Thanks K**bleep**ij. I think this issue was solved by release reset signals for related register. Although I do not know the detail but it is workable when software configure this registers. so I guess it may like some switchs must be enabled to download FPGA status from FPGA internal status register to external JTAG GUI. thanks again for focusing on this topic.
