TX2i now fails to flash (or boot) Dead emmc?

We recently had a TX2i that was not booting properly (no information being posted to the system console). We hooked up to it and attempted to flash it, which fails, it looks like maybe the emmc is toast.

Any suggestions?

hello SrJsignal,

couple of suggestion for your testing,

  1. may I have more details, could you please share your commands that you’re used for flashing.
  2. since you’re still able to enter forced-recovery, are you able to flash last-known-good image to the target.
3

  1. ./flash.sh jetson-tx2i mmcblk0p1

  2. This is a known-good image.

The system stopped responding (booting) one day this week. Nothing was coming out on the console, so as a last ditch effort we attempted to flash a known good image. I have the exact image up and running on a different tx2i.

Hi, are you using custom carrier board? If so, which version design did you follow, B04 or C02? Please check OEM DG for detail design difference between them.

5

This occurs on either our custom board or the devkit board. Also, I need to reiterate, this system was working fine for months, another TX2i is currently working on this exact carrier board, with the same firmware / OS load.

The power supply sequencing / discharge is not an exact match for either B04 or C02, I do not see anything else in the design guides showing much difference. Our design is controlled by a microcontroller, and in general does not use the power button functionality. The pin is held high.

My goal is really to just understand what failed so we can do a failure analysis and risk analysis for using this product in our designs. If the eMMC is a weak point, that is not a good thing at all. If on the other hand this is an “infant mortality” issue, then we need to make sure our pre-ship testing runs the eMMC long enough to show early failures.

6

If your other TX2i can work on same carrier board, then the previous TX2i module might already be broken. You might need RMA, there might be a report on this to show the root cause.
