Subject: Copy files to jffs2 partition have problem
Date: Thu, 5 Feb 2004 01:15:52 +0800 [thread overview]
Message-ID: <00e301c3eb42$8dfbbc80$030910ac@linuxer> (raw)
Hi all,
I have used uClinux on my Samsung ARM7 board,
My flash (MX 29LV320TTC- 4MB) have
+ configurations:
static const struct awtel_info awtel_flash_board_desc[PHYSMAP_NUMBER] =
{ // DATA Flash configuration
"MX FLASH", // name
0xE0000000, // window_addr
0x400000, // window_size
2, // buswidth 16 bits mode
5, // num_partitions
},
+5 partitons:
{
name: "Whole partition",
size: 0x400000,
offset: 0x000000,
},
{
name: "Bios partition",
size: 0x010000,
offset: 0x000000,
},
{
name: "Kernel partition",
size: 0x1e0000,
offset: 0x010000,
},
{
name: "Data partition", // jffs2 fs on this
partition
size: 0x1e0000,
offset: 0x200000,
},
{
name: "Configuration partition",
size: 0x010000,
offset: 0x3e0000,
},
In amd_flash.c:
static const struct amd_flash_info table[] = {
....
//This my flash setup
mfr_id: MANUFACTURER_MX,
dev_id: MX29LV320T,
name: "MXIC MX29LV320T",
size: 0x00400000,
numeraseregions: 3,
regions: {
{ offset: 0x000000, erasesize: 0x10000, numblocks: 48 },
{ offset: 0x300000, erasesize: 0x10000, numblocks: 15 },
{ offset: 0x3f0000, erasesize: 0x02000, numblocks: 8 },
}
....
}
BUT I always go problem when copy files:

------------------------------
Please help me if someone overcomes these problem or give me some hints.
+ Why i got errors when i copy files to jffs2 partition even my free space
enough for Garbage collection ( 5*64k = 320k < 664.0k)?
+ "MX FLASH: write to 0x3a59c0 failed. datum = 14000010, verify = 10
Write of 71 bytes at 0x001a597c failed. returned 0, retlen 68"
=>Why it write 71 bytes?
+ Did I set up something wrong with my flash?
Thanks a lot.
