marsic,

Can you share the complete logs including the steps followed? 

Dear sir:

marsic

Lin,

1. I don't understand what is the DDST-UI app doing. Can you explain?

2. When you run the application without mounting the JFFS2, I think it is running fine, according to your original post. Can you confirm this?

3. If this is required, can you just try to mount the JFFS2 volume to some other directory other than /mnt/data and see whether the same behavior occurs?

Dear sir:

1. That is my ap.
     inital V4L2 -> Get Image from V4L2 -> Do previewer resizer -> post image to frame buffer

2. Yes, it's fine.

3. I mount /data or /mnt/jffs2, it same.

marsic

Marsic,

Is you application doing any read/write to the data partition? Can you tell me which all paths its trying to access? 

Dear sir:

if you mean jffs2 partition, I try

/data
/mnt/data
/mnt/jffs2

the condition is same. And application does not access those paths.

marsic 

Marsic,

Can you try the following commands before and after mounting and share the logs?

1. df (disk free)

2. fdisk -l

Dear sir:

# df

Marsic,

Lin Marsic said:

/dev/mtdblock6 1024 384 640 38% /mnt/jffs2

After running the app can you check the free space in the system? Can you share the df logs after running the app?

Dear sir:

1. has mount jffs2 & run AP

Marsic,

Can you try this quickly. Can you enable a print inside the kernel function nand_do_read_ops(),  nand_do_write_ops() in the kernel file drivers/mtd/nand/nand_base.c? Also print the from and to of the functions and share the logs.

Also meanwhile can you mount jffs, try application, unmount jffs, try your application again and see?

marsic

Marsic,

From the logs there are few things to be tried or thought about.

1. We are seeing read transfers only and there is no write to NAND(assuming that you've enabled prints for write also.

2. The key finding is that it is not just happening with your application. I happens during unmount or basically any other command. 

3. You are printing the size of the transfer instead of the from and to arguments, which is for the NAND flash offset being read. Can you correct the printk and send the logs again? 

Dear sir:

1. AP only read rootfs(cramfs) ,so only see read log
    And AP do not access jffs2,
2. the log is follow

Marsic,

This is becoming a very interesting problem. Is it possible to share one of your board? I'll debug and send it back, if this is okay with you.

Dear sir:

If I send my board to you. Where I send???
