At this stage there's nothing fancy going on, it's almost like communicating to a regular shift register. Probably you can attach screenshots from your LA so that one wouldn't need to install custom software to take a look? --- ** [tickets:#318] adapter driver presto - not work** **Status:** new **Milestone:** 0.11.0 **Created:** Wed Sep 08, 2021 07:25 AM UTC by Michal Hucik **Last Updated:** Tue Sep 14, 2021 12:32 PM UTC **Owner:** nobody I'm trying a first time to use Asix PRESTO with OpenOCD. (this Presto is normally working with the Asix UP software for Windows) I tried to use in Windows precompiled OpenOCD 0.11 and in Linux fresh compiled by me. In the configuration I use "adapter driver presto", or in addition "presto_serial 013979". However, on both systems, OpenOCD cannot correctly initialize PRESTO. ==== Linux dmesg ==== [395089.615983] usb 2-2.2: new full-speed USB device number 29 using uhci_hcd [395089.820689] usb 2-2.2: New USB device found, idVendor=0403, idProduct=f1a0, bcdDevice= 4.00 [395089.820693] usb 2-2.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [395089.820694] usb 2-2.2: Product: ASIX PRESTO [395089.820696] usb 2-2.2: Manufacturer: ASIX [395089.820697] usb 2-2.2: SerialNumber: A6013979 ==== OpenOCD --debug ==== Debug: 56 5 presto.c:139 presto_open_libftdi(): searching for PRESTO using libftdi Error: 57 7 presto.c:149 presto_open_libftdi(): unable to open PRESTO: usb_open() failed Error: 58 8 presto.c:540 presto_jtag_init(): Cannot open PRESTO Debug: 59 8 command.c:629 run_command(): Command 'init' failed with error code -100 --- Sent from sourceforge.net because openocd-devel@lists.sourceforge.net is subscribed to https://sourceforge.net/p/openocd/tickets/ To unsubscribe from further messages, a project admin can change settings at https://sourceforge.net/p/openocd/admin/tickets/options.
