GlennCB Posted October 14, 2022 Share Posted October 14, 2022 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 Link to comment Share on other sites More sharing options...
0 attila Posted October 17, 2022 Share Posted October 17, 2022 Hi @GlennCB Please verify in Windows Device Manager under "USB controllers" if "Digilent ADP3450" or "Unknown USB Device" is listed, or lsusb if you are using Linux. If it is not listed, contact for replacement the support.digilent at ni.com specifying the Date of Purchase, Seller and Purchase Order/ Web order Number.

0 GlennCB Posted October 17, 2022 Author Share Posted October 17, 2022 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 Link to comment Share on other sites More sharing options...
0 attila Posted October 17, 2022 Share Posted October 17, 2022 Hi @GlennCB On the UART it should print host detect, "USB Connect 1" after "Running". It is probably a IC53-USB3320C/R353 fault. Please ask for replacement. Link to comment Share on other sites More sharing options...
Question
GlennCB
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
