I cannot remember or reproduce exactly since it was 2 weeks ago and I detached chip from raspberry pi

and also chip is not stock, it is detached from commercial router product (router rom)

As far as I remember

While writing,  flashrom fall into infinite loop in some memory region 

and I manually abort with ctrl+c.

So I tried writing using force option, it works well

I attached force_write_log file to this email
