Flashing multiple TX2s at the same time?

Autonomous Machines Jetson & Embedded Systems Jetson TX2
1

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.

Cutting and pasting the multi_flash_tegra.sh script launches multiple processes, but they all fail.

I manually executed a flashing command by hand:

$ sudo ./tegraflash.py --bl nvtboot_recovery_cpu.bin --sdram_config P3310_A00_8GB_Samsung_8GB_lpddr4_204Mhz_A02_l4t.cfg --odmdata 0x1090000 --applet mb1_recovery_prod.bin --cmd "flash; reboot"  --cfg flash.xml --chip 0x18 --misc_config tegra186-mb1-bct-misc-si-l4t.cfg --pinmux_config tegra186-mb1-bct-pinmux-quill-p3310-1000-c03.cfg --pmic_config tegra186-mb1-bct-pmic-quill-p3310-1000-c03.cfg --pmc_config tegra186-mb1-bct-pad-quill-p3310-1000-c03.cfg --prod_config tegra186-mb1-bct-prod-quill-p3310-1000-c03.cfg --scr_config minimal_scr.cfg --scr_cold_boot_config mobile_scr.cfg --br_cmd_config tegra186-mb1-bct-bootrom-quill-p3310-1000-c03.cfg --dev_params emmc.cfg  --bins "mb2_bootloader nvtboot_recovery.bin; mts_preboot preboot_d15_prod_cr.bin; mts_bootpack mce_mts_d15_prod_cr.bin; bpmp_fw bpmp.bin; bpmp_fw_dtb tegra186-a02-bpmp-quill-p3310-1000-c01-00-te770d-ucm2.dtb; tlk tos.img; eks eks.img; bootloader_dtb tegra186-quill-p3310-1000-c03-00-base.dtb" --instance /dev/bus/usb/002/

Command tegradevflash_v2 --instance /dev/bus/usb/002/059 --oem platformdetails chip chip_info.bin

That’s the failure.

I disconnected the other TX2s and moved this one to being plugged directly in the the PC.

The above command still fails, BUT, since it’s now the only TX2 attached, I immediately reran the command leaving off the --instance parameter, and it worked.

That’s the only difference between working and not-working: the presence or absence of the --instance parameter.

Is this a known issue?

Flashing is about 4-5 minutes per TX2 and we’d like to parallelize that to keep our production time down.

I searched via devtalk’s search and Google and could only turn up one post asking about this for TX1s, with an answer of “it can’t be done”. I assume that post predates the instructions in the documentation I mentioned above.

Interesting!

stracing reveals that the first process in the sequence opens the USB device successfully, twice:

[pid 30311] open("/dev/bus/usb/002/062", O_RDWR) = 3
...
[pid 30311] close(3 <unfinished ...>
[pid 30250] <... read resumed> "B", 1)  = 1
[pid 30310] write(1, "--skipuid ", 10)  = 10
[pid 30311] <... close resumed> )       = 0
...
[pid 30311] open("/dev/bus/usb/002/062", O_RDWR <unfinished ...>
[pid 30310] <... write resumed> )       = 1
[pid 30250] read(4, "R", 1)             = 1
[pid 30310] write(1, "[", 1 <unfinished ...>
[pid 30250] write(1, "R", 1R <unfinished ...>
[pid 30311] <... open resumed> )        = 3

Every other process is getting ENOENT:

[pid 30335] open("/dev/bus/usb/002/062", O_RDWR <unfinished ...>
[pid 30334] <... write resumed> )       = 1
[pid 30250] close(5 <unfinished ...>
[pid 30335] <... open resumed> )        = -1 ENOENT (No such file or directory)

After this /dev/bus/usb/002/063 exists, so there’s some problem where the TX2 re-enumerates and the “–instance” handling doesn’t know to account for that.

shows the existing instance being opened, and its incremented version later on, and a bunch of other USB devices.

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.

One of the relevant Forum thread,

For production line flashing, we will need to check if we have such testing data. Another common way is to use gang programmer to duplicate the flash image.

3

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 post, I believe I discovered the exact problem: during the normal flashing operation, the TX2 will re-enumerate on the USB bus, and it will come up at a different device number.
When flashing a single TX2, the flash.sh and friends all just use the TX2 attached to the bus, without regard to its bus & device numbers.
When flashing multiple TX2s, the flash.sh and friends get passed a ‘–instance /dev/bus/usb/002/064’ reference to the TX2, which is invalid once the re-enumeration occurs and the TX2 comes up at /dev/bus/usb/002/066 instead.

nVidia’s tooling needs to track the attached TX2s better. ‘tegrarcm_v2 --uid’ appears to get a unique serial-number-type identifier from the TX2, that identifier should be passed instead of the USB bus device reference.

I’d fix the scripts myself, but some of these programs are compiled binaries. Is it at all possible to get the source code for those? We can sign an NDA.

I’m flashing the image to the internal storage on the TX2. A gang programmer (where you plug in many SD cards for example) isn’t relevant here… unless… does nVidia have gang programming devices for TX2s? We’d buy that.

4

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 issue.

5

My original testing was on a native Ubuntu 14.04 host.

I intend to run flash.sh from within a docker container though.

6

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.

7

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.

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
9

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. (The Docker daemon is running though.)

multi_tegra_flash.sh created as per instructions from the html page in the Jetpack install.

Both TX2s in recovery mode, attached via USB to an Anker powered hub, then to my laptop. Since I know people will ask, I re-ran the test with the TX2s attached directly to my laptop, no change. Those results are the second batch below.

This is 100% reproducible on my setup, and should be 100% reproducible by nVidia or anyone.

You can see here that the TX2s have re-enumerated on the USB bus. Since the new numbers no longer match the old numbers, ‘–instance /dev/bus/usb/002/008’ fails.

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 with a “.txt” suffix if the name is not liked by the filters.

No kidding. Okay, I’ve added the logs as zipped tarballs, but I’m going to leave the post as is.

Edit: Also added the multi_tegra_flash script to the other post.

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

Huzzah! Yes, this worked. The switch from ‘/dev/bus/usb/xxx/yyy’ to the USB physical tree ‘1-4.2.3’ descriptor is the difference. Since the physical location of the TX2 never changes it’s always the same and the existing tooling works just fine.

Yes, I tested the new multi flash script inside Jetpack 3.1 as that’s what we’ve standardized on for production purposes at the moment. So… it always worked, the 28.1 documentation wasn’t correct. :-)

Thanks all for the help!
