Hi There,

Here we have situation with xavier for long time.

Hardware: T194A/B

Main issue:
Xavier was working with SW9.0, and working well, but it was crashed now, problem as below:

Xavier A not able to book, we can reflash the xaiver with ubuntu16 and SW9.0 environment (upgrade the python to 3.7 with pip 3.7) to reflash it with option to reflash xavier A, output is still xaiver A desktop picture from HDMI XavierB. (this is because ttyUSB2 is not accessable, while ttyUSB3, ttyUSB6 are all accessable)
Then we tried to reflash the aurix with windows infineon software , seems it works, the firmware we were using as below:
DRIVE-V5.1.0-E3550-NV-Aurix-IFW-StepA-1.29.00
DRIVE-V5.1.0-E3550-NV-Aurix-UPDATE-StepA-1.29.00
DRIVE-V5.1.0-E3550-EB-Aurix-With3LSS-3.02.07
DRIVE-V5.1.0-P3479-EB-Aurix-With3LSS-3.02.07
DRIVE-V5.1.0-P3479-NV-Aurix-UPDATE-StepA-1.29.00

but could not resolve the problem.

we tried to reflash the different version including 10.0, 5.2.6, seems was successfully, but was only for XavierB as well, xavier A always not able to book.

Now recently all the version reflash failed, we can’t access all the USB port including ttyUSB 2.3.6, but with ubuntu 18, seems when reflash 5.2.6, USB3 is still accessable (not sure, will post some information later).

And also always when you poweroff the xavier, you can’t poweron same day, always waiting for the next day to poweron it (poweron here means fan works, LED on board flashing continuely), minutes later, the IP from router terminal list will dispear (seems it’s dead again), but before that, may able to access via minicom -D /dev/ttyUSB3.

currently SW9.0 with ubuntu 16 log as below:

6:47:30 DEBUG: running command < true >
16:47:30 INFO: command finished successfully

we changed the 2nd power supply, issue is similar, seems it’s not power supply issue. voltage is as below

BTW, once we can access the xavier via putty terminal, always USB14 is accesable, not USB4, minicom configuration is not sure in right status or not.

appreciate if anyone can help to solve the issue.

Tonight we tried again to flash with 5.2.6 and succeed again for XavierB, failed again for XavierA, voltages showing different with the last access via aurix shell, also xavier B can reboot in 20 mins after power off and working stable (but some issue such as can’t install gdm3 in xavier B via ssh).

Xavier A not accessible.

Thanks if anyone can help.

BTW. I think as we reflashed with 5.2.6, could be not able to flash with SW9.0 again directly even if we could fix the boot issue of xavier A?

And, is possible hardware broken?

Some additional information from aurix shell:
with both power supply, same issue happens, aurixrest and poweron x1 will have below feedback: (poweron without x1/x2 works, but once again, all failed, also unplug the power supply for harlf hour, still failed, guess back to original status to wait for over night for XavierB boot again.)

Dear @james.gao,
Do you see Tegra A booting(fans running)? Also, please share minicom configuration pagedetails for /dev/ttyUSB2 interface.
Also, please share complete flashing(~/.nvsdkm/) folder logs Tegra A flashing

VickNV · June 6, 2022, 12:57pm

Hi @james.gao

Please also review DRIVE AGX Developer Kit Hardware Errata and DRIVE AGX Developer Kit Mechanical & Installation Guide (PDF) and ensure that you have followed them carefully.

james.gao · June 6, 2022, 2:56pm

[quote=“SivaRamaKrishnaNV, post:5, topic:216551”]
lease share minicom configuration pagedetails for /dev/ttyUSB2 interface.

Both Fans mounted the xavier dev kit shell were running if boot the xavier B successfully, how to justifiy which fan related with Xavier A?

Please refer to the log of xavier A flashing, for the minicom, we did nothing for configuration, just as default.

Thanks you for the quick feedback and help.

james.gao · June 6, 2022, 2:57pm

Yes we know that, but not sure every time was following it as not only one engineer working on it before. so we would like to know the hardware is broken or not.

james.gao · June 6, 2022, 3:06pm

For SW9.0 relash with ubuntu 16, log as below.

Could you double check if the file exists with execution permissions?

VickNV · June 7, 2022, 6:03pm

Hi @james.gao
Based on the Aurix voltage report Tegra A SOC voltage is down. Was this system in a car or a truck? What happened prior to the faulty behavior? When was this system purchased? Thanks.

SivaRamaKrishnaNV · June 15, 2022, 5:26pm

Dear @james.gao ,
Could you provide any update?

james.gao · June 28, 2022, 4:24am

Sorry was busy recently. the system was in a testing car, it was working well, the issue is the last few months during it working well, Xavier A was able to mount the external USB SSD disks, while Xavier B couldn’t. no other issue.

Engineer team moved the xavier back to office, and updated some code and encoding on xavier, still working well, but after that, we reboot the system then found that xavier A couldn’t boot any more, untill now.

Now acctually whole system mostly couldn’t boot at all, we purchased it at 2019.

If the system was purchased in 2019, the warranty expired a long time ago.
I would suggest you offline contact your nvidia representative on this.

Thanks we did it, still awaiting for the response.

BTW, recently we can connect with ttyUSB3 now, but at windows of PC end it’s COM14 always, and we can reflash the aurix firmware successfully always, but never can boot it up or poweron it (both xavier A and xavier B). so can you propose the latest version of aurix firmware and we may need to get the package if possible.
