Network Connection in Ubuntu rootfs LS1028ARDB

[anesarkar]

Hi,

    I am getting the following error after I build the ubuntu image on SD card and boot it on LS1028ARDB.

After I log into emergency mode, I am not able to connect to any network. Is the error because the image was not built correctly?

Hello Anish Nesarkar,

Please try the ubuntu rootfs filesystem built from BSP 0.3 release, I uploaded it as the following.

Please refer to my Linux booting up log in the attachment.

Thanks,

Hi,

    I followed these steps:

1. flex-installer -b bootpartition_arm64_lts_4.14.tgz -r build/images/rootfs_ubuntu_bionic_arm64.tgz -f firmware_ls1028ardb_uboot_sdboot.img -d /dev/sdX

2. Stopped at boot menu

   a. tftp 0xa0000000 wyp/ls1028ardb/Image

   -> error: serverip not set

   b. setenv serverip 192.168.2.1

   -> error: ipaddr not set

   c. dhcp

Any suggestions?

Hello Anish Nesarkar,

Please use the following commands to boot up the system.

=> setenv bootargs "console=ttyS0,115200 root=/dev/mmcblk0p3 rw rootwait earlycon=uart8250,mmio,0x21c0500"
=> ext2load mmc 0:2 0xa0000000 /Image
=> ext2load mmc 0:2 0xb0000000 /fsl-ls1028a-rdb.dtb
=> booti 0xa0000000 - 0xb0000000

Please deploy Ubuntu rootfs in partition mmcblk0p3 of the SD card, please make sure your SD card is large enough.
