Dear TI Engineers,
One of my customer encountered below issue about AM3352,
1) Use TF for memory, 2 partition--Boot and rootfs, Boot for Uboot and kernel, FAT format; rootfs is Ext4 format , files are generated by Yocto tool; several 3rd software such as mysql, redis, openstack, MessageQueue, webserver is in the filesystem
2) TF card is handled by MMC0 controller of AM3352, 48MHZ
3) When products with above configuration have spent 2~3 months ion site. Many of them have file system damage information. Most apps is located in /OPT Directory. After test, we found there are some W/R operation from apps and 3rd middleware, and Ext4 file system in TF card got damage.
So my questions are:
1) Is it suitable to choose TF card for this environment? Any better idea?
2) is it possible to avoid if we use lower frequency such as 24MHZ or even lower?
3) Any other suggest for solve this problem ?
Thanks a lot . Look forward for your feedback.
