Hello there,

I reinstalled my Nvidia Jetson Xavier. but I’m missing the ./flash.sh script.

Thanks a lot!

Hi aumattbro,

Please use SDK Manager to uninstall you used JetPack and download again.
You also can download L4T Driver Package and Sample Root Filesystem from here: Jetson Linux R32.7.1 Release Page | NVIDIA Developer

Thank you, for your answer!

How can I select the file, he wants to download it automatically and put it in a folder.

Hi aumattbro,

Run SDK Manager, on Step 1, under the installation step numbers, click the Repair/Uninstall hyperlink to uninstall JetPack folder.
Please reference detail from: Install Jetson Software with SDK Manager :: NVIDIA SDK Manager Documentation

Hi aumattbro,

After change cbo.dts, you need flash by manually.
Please check detail tftp boot steps from Developer Guide.

Flash cbo.dtb
$ sudo ./flash -k CPUBL-CFG -r jetson-xavier mmcblk0p1

Hi aumattbro,

Please reference this topic steps for TFTP boot.

Jetson Xavier boot from TFTP server

Hi yairhav, Please follow below steps and try again: Create /etc/xinetd.d/tftp: service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = -s /home/carol/tftpboot disable = no } Create tftpboot folder on your Ubuntu host machine: $ mkdir /home/carol/tftpboot Generate encrypt kernel and kernel-dtb: $ ./l4t_sign_image.sh --file rootfs/boot/tegra194-p3668-al…

And using full flash by manually.
$ sudo ./flash.sh jetson-xavier mmcblk0p1

i have an tftp server, but what i mean is:

i change my cbo.dts to this

/dts-v1/;

/ {
compatible = “nvidia,cboot-options-v1”;
boot-configuration {
/* nvme boot-order can be in “nvme:C”, “nvme:pcie@”, or “nvme” format /
boot-order = “net”, “usb”, “nvme”, “emmc”, “sd”;
tftp-server-ip = /bits/ 8 <192 168 0 1>;
dhcp-enabled;
/ remove dhcp-enabled if uncommenting static-ip configuration /
/ static-ip = /bits/ 8 <0 0 0 0>;
* ip-netmask = /bits/ 8 <255 255 255 0>;
* ip-gateway = /bits/ 8 <0 0 0 0>;
*/
};
};

then i do dtc -I dts -O dtb -o cbo.dtb cbo.dts

after this i flash my nvidia.

after the flash, i restart my nvidia, but he still boot normality. not over net. I dotn see a DHCP Discover request anything…

[aumattbro]

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

What IP are you asking?

The host IP or how the device gets its own IP?
