[ECOS] Flash problem with Intel P30

[ECOS] Flash problem with Intel P30

[Abraham Celik]

Hi Guys,
 
I am using an intel 28f256p30B flash on my ixp425 board. I get the following
upon boot up:

_________________________________________________________
 
+**Warning** FLASH configuration checksum error or invalid key

And now it stays like that. 

The question i have is how do i set up the flash system locking/unlocking
mechanism for the P30 series. How do I change the flash size to suite the
256P30?
 
I notice when it boots up it says ""FLASH: 0x50000000 - 0x50020000, 4 blocks
of 0x00008000 bytes each"". How do I increase the number of blocks
available?

I can upload things to RAM, but cant create/move them to flash due to the
=a2 or =a92 errors. I imagine that I could try and unlock sectors manually,
but it seems that the flash size is reporting incorrect.

Any ideas?
 

Regards, 

Abraham

My guess is that your flash device is being wrongly identified, or the
configuration parameters are wrong. You need to take a close look at
the hardware specific part of the flash driver in
packages/devs/flash/arm/ixp425 and the generic intel strata flash
driver in packages/dev/flash/intel/strata.

Hi Andrew,

I agree that I have something not set up correctly.

Its not the correct flash for the IXDPG425, however the changes that were
recommended for the switch to the P30 do not work as hoped.

I was actually hoping that someone had already gone through this major pain,
and could shed some light on how they fixed it, or better still, if someone
could point me in the right direction of how to fix it.

I know that its not configured correctly, but where do I start to learn how
to fix it?

Abraham

You need to look at the code in the driver. Put in some debug prints,
find out what happens in the flash_hwr_init() function. Basically, do
some debugging.

I suggest you use a ram version of redboot, not a rom version.
