uSD card detection error
Added by iseori kang 1 day ago
Hello,
After a certain point during the Temperature Cycling Test, a uSD card insertion error occurred.
The uSD card remained seated and recovered spontaneously after repeated occurrences.
This is the dmesg at that time.
Please check it related.

RE: uSD card detection error - Added by Michael Williamson 1 day ago
Hello,
Can you provide any additional data, e.g.:
1) what was the ambient or the die temperature was of the CPU at the failure point?
2) How many failures did you see? 1 or more? If more, at the same temperature?
3) What SD card was being used?
4) What SOM was being used (model number)?
5) What CPU operations were in progress (e.g., were you running an IO test on the SD card, an application, linux IDLE, etc)?
6) What kernel version you are using?
7) What SDK / Filesystem you are using?
Thanks!
