I am using Dediprog programmer and currently using 8192 kB SPI Winbond "W25Q64.W" chip. Currently my time to erase chip is in excess of 10 mins. On the programmer i can see it is working in 4 KB chunks at about 4 chunks per second. So very roughly 16 KB/s.
Is this right? Is there any way to erase a chip faster.
Any insight on this matter would be greatly appreciated.
Regards,
Anthony Enos

For now I can only confirm, that it is normal that flashrom works at the smallest possible chunks for erasing. I can not comment on the speeds you are seeing based on facts but I *think* it should be way faster. Which flashrom version are you using?
