Hello. Actually it was a wiring problem. I've tried with both /WP and /HOLD tied to GND, then with /WP tied to GND and /HOLD floating. This morning I saw, that /WP and /HOLD should be tied to VDD (this is noted for the Amontec JTAGkey/JTAGkey2/JTAGkey-Tiny programmer). After tying them to VDD everything worked fine.
Sorry for the inconvenience.

Hi, that looks like erasing worked only sometimes... well, most of the times, but not always. Have you connected all pins of the flash chip? Is it still connected to a board? In the latter case please see http://flashrom.org/ISP for possible culprits.
