Hello Paul, you're right! It seems that the whole problem is only in udev permissions. PRESTO is now connected (as root) - unfortunately it doesn't seem to be very fast. Now I will try to connect JTAG to the neorv32 RiscV for gdb session.
Problem is solved - I apologize for the commotion. Michal ==== OpenOCD ==== Info : PRESTO open, serial number '' Info : setting speed to 0, max.

(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 [email protected] 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.
