Serial flash AT45DBxx1D is obsolete.
I have substituted it with the new AT45Dbxx1E model but I have problem using it
as boot flash.
Fails when programming the IDBLOCK.
Does anyone found a solution?
PS: I'm using it on a Rabbit 6000 board (RCM67xx).
TIA

I've just received this email:
use AT45db321E-shf which is 32 bit and available ok. pls answer me if this is helpful
for you or not

I've already tested the AT45db321E-shf.
It doesn't work.
When trying to configure the IDBLOCK on RCM6700 I get and error just after "Erasing flash..." disappears (I'm using DynamicC v.10.72).
Have you another solution?

I assume you are using Dynamic C, did you edit flash.ini to include the new
part?

The model I'm using (AT45DB321E) is already included in flash.ini, but it
is erroneously detected as a AT49F002T [1F08].
The AT45DBxx1E has a 2 bytes status register.
The AT45DBxx1D has a 1 byte status register.
I've modified the source code in order to work correctly with 2 bytes status register devices, but I can't anyway load the IDBLOCK correctly.
Someone has something more to suggest?

looking at the flash.ini file, I think the AT45DB321 entry there is a typo as
the device characteristics are all wrong and the Manufacturer/device ID of 1F34
is not correct. I don't know why it is id'd as an AT49F002T as that
has device ID 1F08 and the AT45DBxx1E is 1F27. Have you added a correct entry
for the AT45DBxx1E with device ID !F27 to the file?
