Hi
I added the following lines in fs/jffs2/debug.c
In __jffs2_dbg_acct_sanity_check_nolock
I use a intel 8MByte NOR flash P33.
int i_dbg;
JFFS2_ERROR("c->nr_blocks = 0x%#08x\n", c->nr_blocks);
for (i_dbg = 0; i_dbg <= c->nr_blocks; i_dbg++)
{
*jeb_dedgb = c->blocks[i_dbg];
JFFS2_ERROR("c->blocks[%d] = 0x%#08x\n",i_dbg,
jeb_dedgb->offset);
}
Strange values in blocks 0 - 4. ( U-boot has reserved the first 4
sectors )
The root filsystem is located from 0x20000 to 0x640000
I added some board specific code below.
