Job Aborted Failure In Uio Create Address From Ip Address Link Now

dmesg | grep -i "pci 0000:02:00.0" | grep -i "BAR" If BAR addresses are shown as [disabled] , you may need to run:

INTERFACE=$(ip -o link | grep "00:11:22:33:44:55" | awk -F': ' 'print $2') IP_ADDR=$(ip -4 addr show $INTERFACE | grep -oP '(?<=inet\s)\d+(\.\d+)3') Then pass $IP_ADDR and $INTERFACE to your application. In embedded systems, the UIO device may not have been created in /dev due to missing udev rules. dmesg | grep -i "pci 0000:02:00

sudo trace-cmd record -e uio -e pci -e net # Run your failing job sudo trace-cmd report | grep -E "uio_create|mmap|addr" Look for -ENODEV (no device), -EINVAL (bad address), or -ENOMEM (mapping failed). int uio_create_address(const char *ip_addr
