With your settings, the chip select high time is 30ns and does not respect the EPCQ256 datasheet (50 ns min).

I think it is only a question of chip select high time. I increased the time between two commands sent to the IP in order to increase the CS high time, and it works for all commands (sector erase, chip erase...).
