Qt + vx cross-compilation environment using sqlite problem?

Use QSqlDatabase is can create a new database file, open is also no problem



But using QSqlquery to create table/query/insert lasterr prompt "disk I/O Unable to exexute statement",

If use the database file is not in the falsh file, but the direct use of memory, in the use of QSqlquery to create table/query/insert is no problem,


Is it the file system format to be the problem? But is the powerpc supports TFFS format! For the great god taught,
