Problems flashing N25Q064A13ESE40E SPI chip

[Ruben Van de Put]

Hello,

I'm having some problems flashing a SPI chip with the BusPirate V3. Writing
the image is successful but verification is not successful.

First try with chip on breadboard and long leads (20-25cm):

Then I shortened the signal leads and soldered them directly on the
BusPirate:

Then I soldered all leads directly on the chip (with an adapter) instead of
using a breadboard:

I also tried lowering the SPI speed to 1 MHz:

Current set-up

Chip datasheet: http://www.farnell.com/datasheets/1674442.pdf
Flash connected in this way: http://flashrom.org/Bus_Pirate

Is there anything else I can try or should I try replacing the flash chip?

Kind regards,
