TMDXEVM365 NAND Flash bad block

I have a question about DM365EVM. The following messages are given for a phenomenon irregularly.

Alignment trap: init (1) PC=0x40004000 Instr=0xe591e004
Address=0x00000007 FSR 0x001

block 346 is bad
block 386 is bad
block 526 is bad

nand_update_bbt: Out of memory
**>> Block 3256 retired
nand_update_bbt: Out of memory
**>> Block 3180 retired

A system does not start. It seems to occur when I continue using NAND Flash.
(bad block continues increasing.)
May it be written in at NAND Flash by a system or a driver? (edmak became the error when I made a route file lead only)

I use only JPEG decode.

I look forward to receiving your  reply.

Sincerely yours,
