[U-Boot-Users] Spansion flash not detected by CFI driver

[Shiju Mathew]

Hello,
I have a spansion flash (S71WS256ND0BFWEP) on my board (Freescale imx31
ADS).I use CFI driver with the below configuration. But I get the
following error(debug message). Could someone help me to resolve the
problem.

[U-Boot-Users] Spansion flash not detected by CFI driver

[Shiju]

Hello,
I have sent this mail in an other mail id. Looks like it hasn't reached
the mailing list. Hence forwarding again. 

I have a spansion flash (S71WS256ND0BFWEP) on my board (Freescale imx31
ADS).I use CFI driver with the below configuration. But I get the 
following error(debug message). I am not able to write to the flash
memory too. Currently I use an other bootloader on the board to flash
uboot. Could someone help me to resolve the problem.

Actually this is already the 3rd time you are sending this.

That's pretty much of a nuisance. Stop doing this.

Sorry for the repeated mails. I have subscribed to uboot mailing list
and somehow my previous two mails(from gmail) didn't came to my inbox.
So I thought it didn't go through. Only this mail came to my inbox.

This is not correct for your chip. You should have this set not less 
than the total number of ease units (blocks) on your chip.

For what I could find on the net this chip seems to have the following 
interesting geometry:

4 x 32kB
254 x 128kB
4 x 32kB

So, the total should be at least 4 + 254 + 4 = 262

Please fix this and provide the logs again...

Thanks Tolunay,
I could fix the flash detection after changing the total no: of sector
to 262. But the flash unprotect sector always times out.The first 4
sectors are protected when uboot comes up. I am not able to update uboot
from within uboot since unprotect sectors  always fails on these(all)
sector. Should I need to change any timeout values.The log is as below.

I have another update. THe protect/unprotect failure was happening only
when I was using h/w protect enable. I disabled h/w protect to see
whether everything else goes well. But timeout happens on write as well.
Below is the log message.

After  disabling the buffered writes, write timeout doesn't happen. ALso
protect/unprotect works well when h/w protect is enabled. Is there a
way to use buffered writes on this flash device.

Try disabling debug outputs in CFI driver. I've seen writes do fail when 
debug output is enabled.

I tested disabling the debug outputs. Still writes and protect/unprotect
fails if CFG_FLASH_USE_BUFFER_WRITE is defined.

Is this chip capable of buffer writes? It is a new chip. It is described 
as Stacked Multo-chip Cellular RAM flash. I do not know. You will have 
to debug a bit to find out why. If your debugging indicates something 
that should be addressed in the driver please submit a patch...
