Hi
I follow below step on Jetson Nano. But I failed to flash.
To RAM boot to NFS
1.Put the device into reset/recovery mode.
•Power on the carrier board and hold the RECOVERY button.
•Then press the RESET button.
2.Execute the command:
sudo ./flash.sh -N <ip-addr-of-linux-host>:/<path-to-NFS-rootfs> --rcm-boot <platform> eth0
Where:
•<ip_addr> is the IP address of the host system
•<root_path> is the path to the NFS rootfs
•<platform> is the target’s platform type: nano, jetson-xavier, tx2, or tx1
Here is the command i used
sudo ./flash.sh -N 192.168.86.145:/nfsroot --rcm-boot jetson-nano-qspi-sd eth0
And I got this err
opying cfgfile(/home/terry/nvidia/nvidia_sdk/JetPack_4.2.2_Linux_GA_P3448/Linux_for_Tegra/bootloader/t210ref/cfg/flash_l4t_t210_spi_sd_p3448.xml) to flash.xml… done.

Failed flashing t210ref.
did I put the right board name ? it is same name I use to flash to sdcard.
Thanks
Hi terry8uwg2,
Please following below steps to NFS boot:
sudo apt-get install nfs-kernel-server
Add rootfs path in "/etc/exports":
example: /home/username/nvidia/nvidia_sdk/JetPack_4.2.2_Linux_GA_P3448/Linux_for_Tegra/rootfs/
sudo /etc/init.d/nfs-kernel-server restart
sudo ./flash.sh -N 192.168.86.145:/home/username/nvidia/nvidia_sdk/JetPack_4.2.2_Linux_GA_P3448/Linux_for_Tegra/rootfs/ jetson-nano-qspi-sd eth0
Hi
So no need give --rcm-boot?
Hi terry8uwg2,
The “–rcm-boot/RAM boot” is not supported on T210 based platforms.
We will modify the L4T documentation.
Sorry for inconvenience.
hello carolyuu,
I did this in accordance with the instructions for the jetson tx2 board,
sudo apt-get install nfs-kernel-server nfs-common portmap
sudo gedit /etc/exports
add this line::
/home/user/nvidia/nvidia_sdk/JetPack_4.2.3_Linux_GA_P3310/Linux_for_Tegra/rootfs/ *(rw,nohide,insecure,no_subtree_check,async,no_root_squash)
sudo /etc/init.d/nfs-kernel-server restart
sudo ./flash.sh -N 10.42.0.222:/home/user/nvidia/nvidia_sdk/JetPack_4.2.3_Linux_GA_P3310/Linux_for_Tegra/rootfs/ jetson-tx2 eth0
it boot from nfs host(10.42.0.222) But at this point it stops with the following message…

You can guide me!!
Hi hhami.2040,
Please check you have below path:
/home/user/nvidia/nvidia_sdk/JetPack_4.2.3_Linux_GA_P3310/Linux_for_Tegra/rootfs/
This is set your local machine rootfs folder path.
Hi carolyuu,
I don’t understand what you mean??
I must,how set it??
please help me!!
Hi hhami.2040,
$ sudo gedit /etc/exports
add this line::
/home/<b>user</b>/nvidia/nvidia_sdk/JetPack_4.2.3_Linux_GA_P3310/Linux_for_Tegra/rootfs/ *(rw,nohide,insecure,no_subtree_check,async,no_root_squash)
<b>--> Please make sure the path is correct.</b>
$ sudo /etc/init.d/nfs-kernel-server restart
Execute the command:
$ sudo ./flash.sh -N <ip-addr-of-linux-host>:/<path-to-NFS-rootfs> <platform> eth0
Where:
•<ip_addr> is the IP address of the host system
•<root_path> is the path to the NFS rootfs
•<platform> is the target’s platform type: nano, jetson-xavier, tx2, or tx1
Example:
$ sudo ./flash.sh -N <b>10.42.0.222</b>:/home/user/nvidia/nvidia_sdk/JetPack_4.2.3_Linux_GA_P3310/Linux_for_Tegra/rootfs/ jetson-tx2 eth0
