Hi @attila Thanks for your reply. The only new devices which show up are the FTDI serial port and the USB hub inside the box. I believe the second port for the JTAG interface is not showing up as I do not see either unknown USB device or the Digilent ADP3450 listed. Here's the output from "lsusb", diffed for what is new when I connect the ADP3450: Bus 001 Device 007: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC Bus 001 Device 006: ID 0424:2512 Microchip Technology, Inc. (formerly SMSC) USB 2.0 Hub When I connect to the serial port, I see this when I boot into standard mode: Press any key for Recovery Mode... S for Standard Mode L for Linux Mode QSPI: 01-20-18-4D-01-80 Programming PL DDR Check BootMode 0x01 Loading Standard Mode PH 0 from: 0x040000 [8] to: 0x130000 [8] PH 1 from: 0x010000 [30010] to: 0x100000 [30010] FsblHandoffExit Running Standard Mode v03.3C PL done QSPI: 01-20-18-4D-01-80 AXI-DMA Setup Setup MAC: 00-18-3E-03-BE-A4 Running And in Linux mode, it boots all the way to the login prompt. Do any of the blue internal jumpers affect whether the JTAG port is visible? Both jumpers appear to be in the default position and moving them had no effect that I could see. -Glenn

My ADP3450 is no longer responding over USB, checked over multiple computers with different cables - all show the same behavior. Serial port is responsive, able to boot into Linux mode or Standard mode, but still no connection with Waveforms. How do I proceed? Is my unit defective? I can't seem to reflash it since it doesn't show up in Waveforms so no recovery modes are available. -Glenn
