[U-Boot-Users] Problem with Strata 28F256K3 Erasing on PXA

[U-Boot-Users] Problem with Strata 28F256K3 Erasing on PXA

[Craig A. Vanderborgh]

Hello again, everyone:

I am having trouble with the u-boot flash code on my target system.  I 
am using the new 28F256K3 Intel chips on this target, instead of the 
28F128J3A chips (which were on my development system).

U-Boot works with the 128J3A's but not with the 256K3's.  I have tweaked 
the flash code so that it's correctly detecting the chips.  And the 
u-boot runs out of these 256K3's when I program it into flash using 
JTAG.  What does not work with the 256K3's is ERASING flash.  And damned 
if I can figure out why.  The u-boot code that is supposed to erase the 
flash just FLIES through in no time at all, without reporting any 
errors.  But then when I try to write the flash-writing-code says "Error 
- flash not erased".

What do you think might be going on?  How might I proceed to debug 
this?  Does anyone out there have some test code that can erase the 
Intel Strata 28F256K3's?

Please advise - I am very lost and frustrated at the moment...

Thanks in advance,
craig vanderborgh

Craig,

I use the K3 Strata flash on our PXA board and I have no problems using 
the CFI driver built into u-boot.  There was no need to write a custom 
driver.
