S25FL128S - erase fails

[Jim Houston]

Hi

I'm playing with a Spansion S25FL128SAGMF1000 and running flashrom on a 
raspberrypi.
I started with a new chip and was successful writing and reading back a 
random
image.  It fails when I try to erase the part.

Probing this part gives several possible chip names and I picked 
"S25FL128S......0".
I'm assuming that the 0 vs. 1 suffix is selecting 64k vs. 256k sector size.

I may put some effort into chasing the erase problem.  Is there anyone 
currently working on this?

I added power supply bypass capacitors closer to the flash chip and the 
erase works.
My mistake.

The "S25FL128S......0" works for read/write/erase.

Thanks.

Cool, thanks for the update!

If for some reason you decide to try the S25FS chips, bear in mind that you
may need to disable the hybrid sector architecture in order for erase
commands to work as expected.

Hello Jim,

thanks for your report!
I have marked the flash chip as fully tested and will commit that later
together with other small changes.
