Hi All
We have designed our own H/W based on DM8168.
In this board we are facing some NAND related issues. that is
the bad blocks keep on getting increases and finaly system reports
the running out of disk space error while trying to write something on Disk.
Board Information
=================
TI8168-GP rev 2.1
ARM clk: 987MHz
DDR clk: 675MHz
I2C: ready
DRAM: 2 GiB
NAND: HW ECC BCH8 Selected

mtd.erasesize = 131072 (128K)
mtd.writesize = 2048 (2K)
mtd.oobsize = 64
regions = 0
For other mtd's the size (mtd.size) will vary
Keep on we are getting the following error message and disk got filled.
Read of newly-erased block at 0x04360000 failed: -74. Putting on bad_list
Read of newly-erased block at 0x04360000 failed: -74. Putting on bad_list
JFFS2: marking eraseblock at 04360000 as bad
we have run the following nand test which are given in Kernel(/drivers/mtd/tests).
mtd_nandecctest.ko
mtd_oobtest.ko
mtd_pagetest.ko
mtd_readtest.ko
mtd_speedtest.ko
mtd_stresstest.ko
mtd_subpagetest.ko
mtd_torturetest.ko
FYI: we have run the same test in TI EVM - Rev-E board also.
and we got the same errors what we got in my board.
we have attached the nand test results
1. nand_test_results.txt --> custom board results
2. DM8168_EVM_nand_test.txt --> TI EVM board results
Please Help us to fix this issue.
Thanks a lot
