Hello,
I am working on a datalogger project and i am using texas ek-TM4C1294XL with my own booterPack. I have lots of sensors connected to my board and i am using freertos to manage my logging.
I am using an sdcard connect on ssi0 port and all appears to be working fine. Then i left my system working stand alone with sensors for more than 7 days (1st test) and more than 3 days (2nd test) and after these days of well functioning i started to have many write errors on sdcard and files started to be filled with strange data in the middle of sensor data like it had noise on ssi databus. Beyond that it started to create lots of folders whose name were sensor strings(!!!) and folders size were dozens of Mbytes(!!!) and they could not be accessed because they were just fake like dozens of other files with no extension and no mean to exists there, which means that sdcard file system were totaly corrupted.
Well my question is if you know some problem similar to mine and if you know if this is a problem related with processor (XM4C1294NCPDT), hardware or firmware and how to explore that because at this time i am without any clever idea to solve that problem.
I hope you could help me.
Thank in advance.
Best regards,
Ricardo Alcácer
