[flashrom] Re: Trouble flashing Winbond chip

[Idwer Vollering]

This could be caused by electrical problems. Did you find and read
this page, https://flashrom.org/Common_problems ?
Also, the particular version of flashrom was omitted in its output. It
looks like you build the binary yourself, instead of installing
through a package manager. Please mention the version as well.
