Hi TIs:
We have two borads with J6ECO(DRA72x) module
They have kernel crash problem when chamber temperature is lower than -25 degrees Celsius
After back to room temperature, the problem has disappeared.
Before kernel crash, we do memory test and result is fail.(See the log below)
Is there better way to distinguish the problem is releated to module or DDR ram?
Thanks!
Kenny
