Start_L4T_Docs.html contains a section “Flashing Multiple Tegra Devices”. It’s pretty straightforward, essentially using the existing subcommands to run the flashing sequence against a specified USB device instead of against the only one that’s attached. My problem is that it does not work. Cuttin…

Hi smacdonald, We have release the latest 28.2 documentation. Could you try this “multi_tegra_flash.sh” script? We have check to flash two tx2 devices, it’s success! L4T R28.2 Documentation: https://developer.nvidia.com/embedded/dlc/l4t-documentation-28-2-ga

smacdonald, You are using 2 Jetson TX2 devices for your testing, correct? I assume “multi_flash_tegra.sh” can be executed. If not, you might need to chmod +x "USB communication failed.Check if device is in recovery => are the USB under recovery mode for all the devices connected? lsusb will tell…

Yes, I have two TX2s. The script is exectuable. Yes, all the devices are in recovery mode. I did not see that thread before, but it only says to check the “Flashing Multiple Tegra Devices” which as I said in my original post, those instructions do not work. In the bottom part of my original po…

I don’t have multiple TX2s to flash, so I don’t know how it behaves in practice. I see something though of interest: The USB re-enumerating. One place this occurs even on a single TX2 is if the host is a VM. Is this a native install host? If it turns out to be a VM this would be a USB re-enumeration…

My original testing was on a native Ubuntu 14.04 host. I intend to run flash.sh from within a docker container though.

You may find issues with docker, one of which will be you need to find a way for docker to own that USB device regardless of enumeration order.

hello smacdonald, we had also saving the flashing log in the background, could you please check and share the log files to us, the file naming would be something like below. thanks flash_${BUS}_${DEV}.log

I had removed those, so I just recreated them. Ah… there doesn’t seem to be a mechanism to attach files, so cut n pasted code blocks it is. Sorry about this. Ubuntu 14.04.5 LTS amd64 laptop, running Jetpack 3.1. This is a native host operation, there is no virtualization of any kind in place. (Th…

Just in case: smacdonald@L087:~/work/va/nvidia/jetpack/64_TX2/Linux_for_Tegra_tx2/bootloader$ cat multi_tegra_flash.sh #!/bin/bash NVIDIA_USB_ID=0955: # create a folder for saving log PID=$$ mkdir ${PID} echo "start flash with PID=${PID}" ## flash all devices in background lsusb -d ${NVIDI…

File attachments in the forum work only on an existing post…you can’t add them while creating the original post. If you hover your mouse over the “quote” icon in the upper right you will see other icons show up. The “paper clip” icon attaches to that pre-existing post. You may need to rename logs wi…

Flashing multiple TX2s at the same time?

The USB bus is passed through to the docker container. The TX2 behaviour on USB is the same on my host natively as it is within the container.
