I am using Mac, and installed Ubuntu18.04 VM on Virtual Box for Mac to flash Jetpack. Downloaded the Jetpack 4.3 Developer preview and followed the command line steps from here: [https://developer.download.nvidia.com/assets/embedded/secure/jetson/JP%204.3%20DP/JetPack%204.3%20Developer%20Preview%20Installation%20Instructions.pdf?kyUvSeU369peI4KYMOVvI9DiXyUEjxhsfLcgF\_38-OB9i-x2YyX8ZNJ5EuoMHGLHQUiXcIIH5zAaVnuQOr5wnOsq2MN4UiFXRwmjNy8Gs8ueyOmCGohjEJKACRxVXfbYUvMBXcv6LiY\_kC2YMviE3I7js8mFM7rhvrCdhCUze-J7TGRYRSLpi8fuk5O-\_mt9ES\_PSrVAiOhkPzk1FIqO4uN7wLY26feFMEIxN5S6DGY](https://developer.download.nvidia.com/assets/embedded/secure/jetson/JP%204.3%20DP/JetPack%204.3%20Developer%20Preview%20Installation%20Instructions.pdf?kyUvSeU369peI4KYMOVvI9DiXyUEjxhsfLcgF_38-OB9i-x2YyX8ZNJ5EuoMHGLHQUiXcIIH5zAaVnuQOr5wnOsq2MN4UiFXRwmjNy8Gs8ueyOmCGohjEJKACRxVXfbYUvMBXcv6LiY_kC2YMviE3I7js8mFM7rhvrCdhCUze-J7TGRYRSLpi8fuk5O-_mt9ES_PSrVAiOhkPzk1FIqO4uN7wLY26feFMEIxN5S6DGY) on doing `$ sudo ./flash.sh jetson-xavier mmcblk0p1` it throws error and breaks the flash. Error: `command tegraflash_v2 --pt flash.xml.bin --create` `Failed flashing t186ref` Solution tried: > 1. lsusb shows Nvidia Corp. > 2. Installed python > 3. Installed xmr > 4. Jetson in recovery mode Any help would be appreciated … I have tried it multiple times, using command line and sdk manager both but its breaking it both cases. ---

Hi Eyshika, VMs are not supported by JetPack/SDK Manager, but you may refer to below topic to see if can help on your case: > [@JetPack 4.X Install with a VM (Solved)](https://forums.developer.nvidia.com/t/jetpack-4-x-install-with-a-vm-solved/65160/6): > > An automation of creating a guest VM for macOS using VirtualBox + Vagrant + Ansible to run the NVIDIA SDK manager including a) automatically building a (custom) kernel and rootfs for Xaviers supporting Kubernetes b) flashing the Xavier from the CLI c) headless OEM setup of the Xavier after flashing … can be found here: [jetson/workflow/guest at master · helmut-hoffer-von-ankershoffen/jetson · GitHub](https://github.com/helmuthva/jetson/tree/master/workflow/guest) Have a look at [https://github.com/helmuthva/jetson](https://github.com/helmuthva/jetson) for the bigger picture.

Thank you for the reply. I am using the same method for VM and still getting error on flashing Jetson. ---

It is important to know that during a flash the USB repeatedly disconnects and reconnects. Even if you see the Jetson with lsusb prior to starting the flash a VM has a very high failure rate due to not reacquiring the USB reconnect. For this to work you would have to guarantee the host o/s never intercepts this and the Jetson is always passed to the VM no matter how often it reconnects. ---

@Eyshika, what sort of VM are you using? VirtualBox? Vmware? Are you able to try flashing from Ubuntu OS without using VM, as the latter method is not officially supported? ---
