We have a problem with several Jetson Tx2i.
We use the Jetsons on our custom carrier board. This Board work properly with other Jetsons and worked with faulty ones for quite some time until the recently turned bad.
We were conducting temperature cycling on several Jetsons on our board and once every few weeks we took it out of the oven to see that the Jetsons work well. In previous times (when we took them out of the oven) it worked well and in our recent try (after a total of about 400 cycles) 2 of the Jetsons have turned bad.
The cycles were from -40°C to 125°C and the boards (and the Jetsons consequently) were unbiased.
When a faulty Jetson wakes up and it sends the following logs in UART:
“MTS error(2) : dram alias check failure
Cpu waypoint 0.5 failed
ERROR: High Layer Module = 0x32, Lowest Layer Module = 0x32, Aux info = 0x1, Reason = 0x6”
We have seen this topic came up in the forums a few times but the cases were different and there was no clear answer.
Also when we tried to burn the tegra flash it failed when it tried to “send blob”. It returned with error – “Return value 1”.
So, our questions are:
- What is the storage temperature of the Jetson?
- Could the problem be related with EMMC? Perhaps could we get some technical manual of the emmc component?
- Do you have any idea what the problem could be and if so, how can we fix it?
- Do you need any additional information?
