Linux version 4.9.11, gcc version 4.9.4
Toshiba NAND 128MiB 3.3V 8-bit, SLC,erase size:128KiB, page size :2048, OOB size:64
nand: ecc-size:512, ecc-strength: 8
some boards have been working for a few days and the application program is unable to write data to FASH, because the ubifs switched to ready only mode.
We searched online and found that TI's AM3352 had similar malfunctions before, which were ultimately resolved through TI's updated SDK.
Please help analyze the cause of the problem together, thank you
