I have a BeagleBone Angstom image that basically polls MODBUS/TCP data on the network from a PLC using a Python script. This image has been run in both the BBB and BBW and we are seeing a periodic crash after a few days of operation if the flash card is branded by Sandisk. If the exact same image is run on a flash card from Transcend we do not see crashes. The kernel is 3.8.13.
The journal includes some lines like shown below about the time of the crash. I would like some help/recommendations about what this means.
Also based on your experience are Transcend cards better? They claim to have ECC features and I cannot find any such claim on the Sandisk cards.
Is ECC a good thing for these flash cards?
