Everything on the buss is a listener. All the gear is off except two are on for testing. This worked two weeks ago under Ubuntu 22.04 and self compiled Linux-GPIB. So this is not the hardware. > What device are you using?

Still stuck in ECIC. I can't get it to do ENOL anymore, now. How can I debug this deeper? davygrvy@workbench:~$ sudo modprobe -r tnt4882 davygrvy@workbench:~$ sudo modprobe -r gpib_common davygrvy@workbench:~$ sudo modprobe -v tnt4882 insmod /lib/modules/7.0.0-22-generic/updates/dkms/gpib_common.ko.zst insmod /lib/modules/7.0.0-22-generic/updates/dkms/nec7210.ko.zst insmod /lib/modules/7.0.0-22-generic/updates/dkms/tnt4882.ko.zst davygrvy@workbench:~$ sudo gpib_config --minor 0 --system-controller --ifc --pci-bus 5 --pci-slot 5 --irq 20 --board-type ni_pci davygrvy@workbench:~$ ibterm -m 0 -d 25 Attempting to open /dev/gpib0 pad = 25, sad = 0, timeout = 10, send_eoi = 1, eos_mode = 0x0000 ibterm>ID? ibterm error: Unable to write to device at pad 25 - ECIC 1: Board not controller in charge ibterm> |
