Failed flashing t186ref with Jetpack 4.6

Hi, using SDK Manager to flash my AGX Xavier development kit with Jetpack 4.6 consistently fails between the 30% and 40% mark with the message “Failed flashing t186ref”.
I’ve attached the relevant log files if it helps to resolve the issue.
Thanks

hello alex147,

may I know what’s your environment setups?
for example, are you using a VM, or a laptop for flashing Xavier platform?

Hi JerryChang,

I’m running Linux natively on a laptop and have already flashed several such boards successfully with SDK manager… I’m wondering of this could be narrowed down to a specific hardware issue, perhaps of the eMMC connection…

hello alex147,

did you mean you have other Xavier platforms that are able to flash successfully?
could you please try putting the device enter forced-recovery mode, using the flash.sh to flash the target manually.
please enter the default installation path, i.e. ~/nvidia/nvidia_sdk/JetPack_4.6_Linux_JETSON_AGX_XAVIER_TARGETS/Linux_for_Tegra/
and… please detect the device with $ lsusb, after that, you should execute flash script as below for confirmation. $ sudo ./flash.sh jetson-agx-xavier-devkit mmcblk0p1

JerryChang, flash.sh failed with this message:

Error: Return value 8

hello alex147,

sorry, I’ll need more details, please collect the complete flashing logs for reference.
btw, did you mean you have other Xavier platforms that are able to flash successfully?

JerryChang,

sure, here’s the full set of logs.
yes, I successfully flashed another identical AGX Xavier dev kit with the same Jetpack version.
so, I think my host machine is set up correctly, just trying to narrow down if it’s a problem with this particular dev kit

hello alex147,

please have a try again to perform flash script manually,
for example,
$ sudo BOARDID=2888 FAB=400 BOARDSKU=0004 BOARDREV=M.0 ./flash.sh -r jetson-agx-xavier-devkit mmcblk0p1
