Tool/software: Linux
Recently, we discovered a serious problem in using AM3352 system of TI. After AM3352 read and write for NAND FLASH chip for a period of time, it will find that the file system is read-only. After restarting, there are probably dozens of seconds of permissions, and then read only after dozens of seconds. When you look up, you see a bit wrong. This should be ffffffff to ffff7fff. The model of the FLASH chip is MT29F4G08ABADAWP.
Please provide technical support. Thank you !
