Hi, Pynq: master petalinux= 2020.1 Vivado= 2020.1 Board: Ultrascale+ (4EV) command to build image: bash scripts/prebuilt\_image Pynq Pynq.bsp aarch64 bion… Successfully I built Pynq image using prebuilt image command. I can see Pynq and jupyternotebook folders after login. But unable to access jupyter notebook. Running ifconfig shows this ```auto xilinx@pynq:~$ ifconfig lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 10 bytes 456 (456.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 10 bytes 456 (456.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 ``` After running **sudo ifconfig eth0 up** ```auto xilinx@pynq:~$ sudo ifconfig eth0 up [sudo] password for xilinx: xilinx@pynq:~$ ifconfig eth0: flags=4099 mtu 1500 ether 5e:47:3d:f6:85:18 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 31 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 150 bytes 7456 (7.4 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 150 bytes 7456 (7.4 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 ``` At boot status it says no etehrnet found ```auto xilinx@pynq:/etc/network/interfaces.d$ Xilinx Zynq MP First Stage Boot Loader Release 2020.1 Nov 12 2021 - 13:24:42 NOTICE: ATF running on XCZU4EG/EV/silicon v4/RTL5.1 at 0xfffea000 NOTICE: BL31: v2.2(release):xilinx_rebase_v2.2_2020.1 NOTICE: BL31: Built : 13:26:05, Nov 12 2021 U-Boot 2020.01 (Nov 12 2021 - 13:23:22 +0000) Board: Xilinx ZynqMP DRAM: 2 GiB usb dr_mode not found PMUFW: v1.1 EL Level: EL2 Chip ID: zu4 NAND: 0 MiB MMC: mmc@ff160000: 0, mmc@ff170000: 1 In: serial@ff000000 Out: serial@ff000000 Err: serial@ff000000 Bootmode: SD_MODE1 Reset reason: EXTERNAL Net: ZYNQ GEM: ff0b0000, mdio bus ff0b0000, phyaddr -1, interface sgmii Could not get PHY for eth0: addr -1 ZYNQ GEM: ff0d0000, mdio bus ff0d0000, phyaddr 1, interface sgmii Could not get PHY for eth1: addr 1 No Ethernet found.
