[U-Boot-Users] Flash erasing problem

[U-Boot-Users] Flash erasing problem

[Takács Áron]

Hi,

first of all I wish you all a happy new year!

I am using a PXA270 based board with u-boot 1.1.2. I'm trying to write an ext2 
filesystem image to flash (I want to mount it read only). First I erase the 
sectors, and I get no error messages. But when I try to copy the image into 
the flash, I get the error message:
Copy to Flash... not erased at 00480000 (ffff0000).
Could anyone please help me in solving this problem? Thanky you very much!

Thanks, same to you.

Please don;t use  old  code.  Update  to  top  of  tree  in  the  git
repository, or 1.1.4 at least.

Which flash driver are you using? Can you erase / program  the  flash
using a JTAG debugger?

Thank you very much for your answer!

I am using a precompiled u-boot image from the board's vendor (Toradex AG.). 
Where can I check the type of the selected flash driver?
I have downloaded the u-boot image to the board via jtag (jflash utility), so 
it is working.
I have some interesting thing in the u-boot output:
Bank # 1: INTEL 28F128J3A
  Size: 32 MB in 128 Sectors

On the board I have two flash chips (2x16MB) of the type 28F128J3C150. 
Is it OK? I think I had to see two bank of 16MB each.

Then you should probably ask the vendor's support folks.

In the source code. You received  the  source  code  or  at  least  a
written offer for it with your board, didn't you?

OK.

I guess it's OK. I don't know your hardware, but most  probably  both
chips  are operated as 2 x 16 bit in parallel to form a single 32 bit
wide bank.

Unfortunately they never bothered to submit their code  back  to  the
public  source  tree. All I know is that Detlef Vollmann once (August
2005) mentioned that there is some port, but  he  never  submitted  a
patch either.

I have the sources, and I'm looking for it, but I haven't find it yet. Any 
hints?

Check if they are using the CFI flash driver (which they probably are
not doing) - is there a CFG_FLASH_CFI_DRIVER in  their  board  config
file  (include/configs/<boardname>) ? If not then they probably use a
custom driver, checke board/<boardname>/flash.c

Where exactly? And what do they provide? A clean patch?

Putting some snapshot somewhere  on  the  web  is  not  the  same  as
submitting any code back to the original project.

You are right, CFG_FLASH_CFI_DRIVER is not in include/configs/boardname.h, and 
there is a flash.c file in board/boardname. Should I try it with the CFI 
flash driver?

It's probably less effort trying to fix their flash driver.

Well, as expected: this is a complete source  tree  of  u-boot-1.1.2,
dated  from  June  2005,  so  it was already half a year old and thus
outdated when they released it.

Bugger them to submit a  proper  patch  here  on  the  list,  against
*current* code.

Sorry, but I don't have time to waste on  other  companies  obsoleted
and unmaintained ports.

Try cp.b command or use 0x207af4 / 4 = 0x81ebd as size in cp command.

I remember seeing similar issue on u-boot pre-1.0 release that I worked on.
I don't recollect the exact driver issue, I think it has some thing to do
with timeout value in erase command.
In my case the u-boot returned the command prompt well before the erase
process is complete.
Try waiting for sufficient time (depending on number of sectors) after
issuing erase command.
Again, it was longtime ago I don't remember the details.

No, this has nothing do with any problems in the code. It was a plain
user error, specifying a bad length with the copy command (4 times of
the intended amount).
